Oshkosh Adventure 2010

I said in the last post that there was no way I could make Oshkosh this year because neither I nor the plane were quite ready. I made arrangements to fly along in a friend's RV8, but he had to cancel out the Thursday before the show due to business commitments.

I decided to guts it up and try to make it. I took Friday off to work on the plane. I figured I had 3 days left to fix, test and fly to get ready.

I decided to blog the trip to try to give some sense to what it was like. Here goes....



I fixed the winglets, sorted the autopilot and throttle issues with the help of my great A&P Dennis Glick (Thanks Dennis!)

By Sunday, I had made several cross country flights, including that trip to Ocean City. Everything was working well and I had gotten comfortable in the plane.

I decided to launch Monday at dawn. I packed and fueled the plane. Then I learned that Oshkosh was flooded out and closed. I went to work Monday and continuously monitored the web site for conditions at Oshkosh.

Finally, it announced in the afternoon that it would be open to new arrivals starting Tuesday morning. I decided to leave at dawn Tuesday. That left me flight planning in the home office for the new weather forecast as depicted above, then trying to sleep.

_______________________________________________________________





Now this is an early start. The moon is still out, but the sun will be rising by the time I finish my preflight and taxi to the runway. I want to be wheels up at dawn.

_________________________________________________________________





The day grows brighter as I fly away from the rising sun. I look back to see the sun silhouetted behind my right winglet. Below me, fog flows like a river through the mountain passes. Gorgeous.

_______________________________________________________________




Humming along at 8,500 feet at 190 knots. The autopilot is working well and I'm a happy camper. Oshkosh here I come.

________________________________________________________________




Time for a quick fuel stop in Goshen, Indiana. Nice folks.

Now, on to Oshkosh. Less than an hour to go!

______________________________________________________________





I made it! Parked at row 358 right next to the flight line. What a prime spot. I can sit next to my pilot side door in the shade and watch the airshow. Countless friends and curious pilots stop by to talk. It was really nice.

_______________________________________________________________




As usual, I'm joined by my old flying buddy Scott, with his wife Glema and son, Alex. Scott landed his Lancair IV within 30 minutes of my arrival and we were parked only 50 yards apart.

_______________________________________________________________





Lunch at the chicken tent, then the obligatory group Eagle One pose with Andy and Brett.

_______________________________________________________________




It was great having the plane at airshow center. No more lugging the literature and chair - just pop them into the plane.

On the bus over from the dorm, an Aussie pilot noticed my Velocity logo and asked if the green plane on the flight line was mine. He said he'd sat near it during the previous day's show and had chuckled about how people criticized what they thought was a hideous final paint scheme.

As fellow builders told me when I was trying to decide whether to fly to OSH in primer, "Builders will get it, and for those who don't get it, who cares?" Still, I look forward to final paint.

_______________________________________________________________





Brett and Andy check out the cockpit. It's a lot of fun to finally show your plane to all of your airplane nut buddies.

________________________________________________________________


Elizabeth camps out under the wing with Hemanshu while we poke around in the cockpit.

_______________________________________________________________





For many in the Velocity contingent, the day started with food and gourmet coffee with the Millins. That was some fine pound cake guys. Thanks for contributing to my forward CG issues.

_______________________________________________________________




The Velocity cookout was well attended and was a lot of fun.

________________________________________________________________


I made several treks to the Millin camp site, home of the Velocity dinner. Here Teresa shows off the Andy Millin Eagle One bobble head doll that is sweeping the nation. She obviously loves this gag.

_______________________________________________________________





The ground was too soft for the fuel trucks so you had to go to hard surface staging areas to meet the fuel truck. No problem. I asked the guy on the scooter and before you knew it, 6 volunteers had appeared to quickly push the plane 50 feet to the hard surface and back. Nice Oshkosh flavor with the Trimotor taxiing past. in the top picture, you can see Dave Bertram had the same idea.

______________________________________________________________




Velocity people are a great community, always sharing ideas, innovations, help and tips. Here two friends improve my rudder handling by shortening the return springs. Thanks guys- I owe you one.

________________________________________________________________




Andy and Darrel check out the plane. Andy looks happy in a Velocity doesn't he?

_____________________________________________________________




Darrel and Norah Kufalk with their beautiful new paint job. Nice work and thanks for showing me all the cool innovations you added. Love the quick release seat mounts!

_______________________________________________________________





This is it, time to head home. I taxi down to the departure end of 36 and wait for my turn. The top picture is the view back 18 toward show center. The bottom picture is the controller on the temporary "tower". He calls "Green Cozy, position and hold on the left side of the runway next to the RV".

I pull out, get the clearance to go and I'm off! Accelerate, lift off, gear up, rock the wings to the show and depart to the right, then head 150 degrees to clear the airspace.

________________________________________________________________




As I skirted Chicago, the weather got kind of iffy. I ended up cruising through light rain at 8,500. Above is a shot of the Chicago skyline from the edge of the O'Hare airspace. Then I had to descend to get under weather around Toledo. After my stop in Goshen, Indiana for fuel, I had to climb over more weather.

________________________________________________________________




I got a chance to use the great performance of the Velocity to get over and around weather on the way home. Over Indiana and western Pennsylvania I climbed to 11,000 feet to get over the clouds. As forecast, it opened up again about 100 miles before home so that I could do a gradual let down and approach.

It was gorgeous flying above the clouds. One highlight was when I came upon a Cessna 182 on the same flight path. I literally passed him like he was standing still. Eat my dust, Spam can!

_____________________________________________________________




Here is a screen shot of the GRT. Yup, that's 208 knots over the ground!

________________________________________________________________




1:15 and safely back at the hangar at Chester County. All told it was about 750 nm in 4 hours with a fuel stop included.

How was it? It was a great trip. I got to finally take a long trip solo and explore the performance the Velocity has to offer. I got to catch up with old friends and make some new ones. It was satisfying to finally fly into the show in my second Velocity. It seems crazy that it was 10 years to the day since I'd done it with my first plane. A lot has changed since then.

The trip has given me a comfort level with the plane that I didn't have before. Really, after flying into Oshkosh, a typical trip sounds pretty straight forward. Two more months before she goes in for final paint, then no more Hulk, Green Hornet, Green Machine, etc.

I put a quick clip from the flight home below just to give a feel for tooling along in your Velocity at 250 mph.

More trips to come......

A Great First Day of Flying

It's been a real heat wave here, with temperatures over 100 degrees every day. I've been doing touchups and repairs in my metal sauna/hangar all week watching the few brave souls flying struggle to get off at our 2200 foot runway with density altitudes in the thousands.

I've decided to base the plane at KMQS, Chester County airport, which has over twice the runway and is only 12 minutes from my house. This was tough as I really love Smoketown and have been here for years. It's the kind of airport community that is tough to find these days- great people.

I don't know exactly how much runway I'll need to take off, especially in this heat and I'm nervous about getting out. Add to that the fact that this is going to be my first solo flight in a Velocity in 10 years.

Any way, I convinced my wife to drive me out to the airport at 7:00 yesterday morning while it was still relatively cool.

________________________________________________________________



Well, here goes. I taxi down to the end of the runway. Stand on the brakes, full power, 2700 rpm and......

______________________________________________________________




Wow! I'm off in 1/3 of the runway. This thing really accelerates.

____________________________________________________________




Back for a low pass at Smoketown, rock the wings to Nancy and Sean, then off to Chester County.

_____________________________________________________________




My Lancair buddy Scott flew his family down for the day for a visit and some fun flying together. We realized that we had never flown in each other's planes when we built our first Velocities.

Here I introduce him to Sean's "My Daddy's airplane is faster than your Daddy's airplane" shirt.
Next, it's off to the airport.

____________________________________________________________




Scott and I flew for a few hours and then at about 8:00, it's time for them to head home. I got a bunch of great tips and techniques from Scott. He got a queasy stomach. I'll only get better from here, Scott.

Here Sean checks out the Lancair IV cockpit.

________________________________________________________




We decide to follow them North a bit and get some air to air pictures. Here Scott taxis up to join me in the run up area prior to takeoff.

___________________________________________________________






Scott pulls up on the left for pictures, then heads North as we turn back for home.

____________________________________________________________







Great shots of our plane in flight. Thanks Glema!

____________________________________________________________




Sean manages to spot our house as we head back to the airport.

"Chester County Traffic, Velocity 929X is downwind for 29 Chester County"

_____________________________________________________________




The view on the taxi back from landing to the hangar. It's 8:30 and the best part of the day with that great golden light. You can't beat taxiing with both doors open and the breeze blowing through.

_____________________________________________________________




Here she is tucked back in her new hangar for the night. What a fun day of flying.

I'm still not sure about making Oshkosh. I shimmed the right rudder out to get rid of an incipient flutter, then tested the plane up to 210 knots indicated today. However, this fix caused an uneven rate of flow from the tanks which I have to fix. I still have to program and set up more GRT functions. I'll see how much I can get done and take it day by day.

In the meantime, I'm finally starting to get to enjoy my airplane. I might take a day trip to the beach next weekend. It's 2-3 traffic filled hours to drive there and 22 minutes to fly to the airport in Ocean City, only a quick walk from the beach.

N929X Returns Home

I have finally been able to fly my own plane at my own airport as I've been dreaming of doing for so long- and it was GREAT! Here is how it went.

Velocity Chief Pilot John Abraham called midweek last week to advise that the plane was working well and all the hours were flown off. I couldn't afford to take the time off from work to go down to Sebastian and fly back with him, so we decided he would fly it up to Pennsylvania Saturday morning, give me some dual and fly home Sunday after lunch.

The very idea of being able to fly up the entire coast from Florida to Pennsylvania before lunch takes some getting used to. (and I can't wait to get used to it)

I watched John's progress on FlightAware.com. As you will see from this screen shot, he averaged better than 190 knots despite winds and bad bumps. Impressive.

When the ETA got to 30 minutes, I drove over to the airport, walked out to the runway and started looking to the South into the haze, trying to spot the plane.

______________________________________________________________




.....then there it was. It looks different than the other traffic and you can tell the sound of a Velocity from other aircraft.

_______________________________________________________________




It looks good. I direct John over to transient parking and run over to say hello.

___________________________________________________________




I'm thrilled that my plane is back, but it's really hot, John's had a long flight and it's lunch time, so we tie her down and head back to the house for lunch. I keep looking back as we walk away- I finally have a working airplane! It looks cool and drew curious pilots within minutes.

____________________________________________________________


Back to the airport to get some dual before dinner. I really enjoyed this. The plane pushes me back in the seat on the first takeoff, we rotate and seem to climb like a fighter plane. This is what I've been dreaming of and is a real contrast to the months practicing here in an Arrow. We fly around just getting comfortable with the handling and avionics then shoot some landings. I manage not to terrify John and actually do pretty well. Time to button her up for the night, then a little more work tomorrow.

_____________________________________________________________




Saturday night and it's finally time to take a deep breath and relax. I can fly, do simple navigation with the GRT's and make a respectable landing holding off the nose gear and everything.

_____________________________________________________________



Sunday morning and off to the airport early. I need to land a lot shorter if I'm going to put it into my 2,200 foot home field.

John uses Google Earth to measure the distance between two taxiway turn offs which are 1,800 feet apart. I need to land after the first and come to a complete stop before the second. We've only got 2 hours to get this down and get over to Smoketown, then get him to the airport in Philadelphia.

I made it a few times and missed it a few times. I need more practice and we are out of time. We decide to swap seats and see if John can do it.

Of course, John was able to put her down and stop in less than half the runway, probably about 1,100 feet. I can't do that at this point.

Here she is safely back in my hangar at Smoketown at last. The blue tape all over the plane marks the little fixes I need to do before flying again, such as reinforcing the NACA inlets, fairing in the rudder/wing junction and getting rid of the popsicle stick spacers, etc. Then, I'll fly it over to Chester County and spend a few days practicing short landings before bringing it back solo.

I'm currently in a situation with the paint shop about trying to get the paint work done. I'm trying not to get put off too far due to missing my slot due to the damage and trip to Sebastian for repairs. It could get painted as soon as next week or as far away as January. You can guess which I'm pushing for. If they can't or won't take me in, I'll look for another shop, but I'd prefer not to as this one does really nice work.

Oshkosh looks hopeless at this point. I just don't have enough time to get comfortable enough for an 800 mile solo trip yet. I'll probably just go commercial. I'm going to shoot for the big canard fly in at Rough River as her unveiling, hopefully in final paint.

Here is a quick video of John's initial landing at Chester County.



More to come next week. Either paint or flying - we'll see.

Final Fly Off Fix Adventures

It's been a while since I posted. I made the switch to an Apple and am still figuring things out. In the meantime, a lot has happened.

The fly off was going on in an expedited fashion down at the factory following the repair to the nose following my unfortunate incident in April. No matter what, you have to expect some glitches and gremlins during the fly off. That's the whole point of the restricted flight test regime. Mine included a number of expected issues and some real puzzlers. I offer the descriptions of the problems and the fixes for the benefit of those who have the fly off period yet to come.

The first issue was a flutter in the rudders at higher speeds. This is easily fixed by shimming them out as set forth below.

Next, there were some rattles and squeaks which were tracked down and corrected. Don't ignore ANY unusual noises or control feel. For example, a clicking noise in one right aileron hinge turned out to be a loose nut on the bolt attaching the aileron torque tube to the bell crank. I tightened it and the noise stopped. If ignored, it would have worn the hole and created slop, or worse.

There were leaks and seeps in the hydraulic system. My A&P at home told me you can't really claim to understand your hydraulic system until you are soaked in red fluid and know what it tastes like. (Then again, he may mean me in particular).

2 weeks ago, John had flown off 20 hours and I went down to Sebastian on Wednesday night with the intention of flying off the last 20 hours on Thursday through Saturday, then flying home with John on Sunday. I ended up having a much more frustrating and much more exciting stay than anticipated.

The plane had been puzzling everyone because the faster it went the more up trim was required, until finally it ran out of available trim. This is the opposite of what is expected. You should have to add more and more nose down trim the faster you go. I don't like atypical problems or mysterious flying characteristics. We decided to see if a stronger trim force would work, on the theory that either the trim spring was weak or not getting enough travel. We added a stronger spring and a 1/2 inch spacer.

This is when the exciting part came along. First, the stronger spring and spacer didn't help at all. I could take it up to 190 knots indicated, but had to pull back pretty hard not to nose down. I then did a sloppy pattern and ended up too high on final. Just as I noticed this, my Aerocomposite prop stuck in cruise pitch. Now I was really high. Add power to go around, again with the prop stuck at cruise, and get a very anemic 100 fpm at full power. Then, during the go around, the down and locked lights flicker on and off. Is the gear down? Better cycle it, only when the gear is cycled, the pump won't stop and the breaker pops. Great.

Nervous landing, then the obvious decision that it can't fly again until all these issues are corrected. I am disappointed, but Duane's comment brings me around, "Don't hate it, fix it!"

He's absolutely right. I am in the best place in the world to deal with crazy issues like this. Honestly, this could have taken me months to fix at my little airport back home. Instead, I got them all sorted out in 2 days at the builders assistance center. I've laid out the problems and fixes below in the hope they help someone out.

____________________________________________________________

The gear light turned out to be a simple adjustment of the nose gear up microswitch arm.

The pitch issue turned out to be the real poser. Scott came up with the answer. There should be a substantial step down from the top of the trailing edge of the canard to the top of the leading edge of the elevator. Mine was flush, with a hair fine gap. It has been years since I built it, and I honestly can't recall if this was a mistake or me trying to finesse a perceived advantage by creating the fine gap.

What was happening is that the low pressure air on top of the canard was staying attached to the top of the elevator. The faster I went, the faster it pulled up on the elevator, forcing the nose down. The fix was to remove and reinstall the elevators at the proper height. This process involved me spending about 4 hours with an air saw, torch and vise grips carefully removing each hinge arm. Then, we added back some chord to the canard trailing edge and reinstalled the elevators.

Here's another "gotcha" you can avoid thanks to me again making the mistake first. I thoroughly sealed my carbon fiber elevators. John looked out at them at 12,000 feet and was shocked to see them ballooning. The lesson: make sure you put several holes in each end of each elevator to allow them to equalize pressure at altitude.



The first try at a pitch fix was a stiffer trim spring. They happened to be laying up a new batch at the time.
Here is what they look like when they are made. We cut and installed one about a third thicker than standard. It didn't solve the pitch problem as mentioned earlier, but I ended up liking the feel better anyway.

_________________________________________________________





These pictures are worth clicking on and studying. This repair is Scott Swing all the way.

When I got the fast build wings from the factory, the trailing edge of the rudder didn't match the trailing edge of the lower winglet at all. Well, no problem I thought, and I just filed down the wing where it met the rudder until it trailed in nicely. Wrong!

The lower winglet was installed wrong and I unloaded the rudder on the winglet by doing so. This caused the rudders to flutter above 150 knots. The fix was to add shims to the rudder. That worked fine- no flutter all the way up to 220 knots indicated. The problem then became the lower winglets again.

Scott simply slit the bottom and top of the trailing half of the winglet, heated and reglassed them. As you can see, they ended up just right with almost no new fill needed. I will add flox and one bid to the winglet side of the vertical gap between the winglet and rudder and replace the shim with flox and microbubbles and it will be ready for final paint.

___________________________________________________________



Here it is with the canard off and ready to repair. I was really tired. Scott Swing was kind enough to come back from home after I got all the hinge arms out and lay up a new trailing edge using I beams clamped to the canard as a guide. The next morning Scott reinstalled the hinge arms in the correct position. The whole fix took less than 24 hours- that would only happen at the factory!

I removed the prop for the propeller service to pick up. I also decided to fix that annoying dump valve seep. There was no puddle of fluid in the keel, but there was always a stripe of red hydraulic fluid from the screws in the belly for the nose gear cylinder all the way back to the cowl. I bought a new dump valve, then used a bottom tap to enable the right angle fittings to seat deeper in the valve body. I changed it out and it solved the problem.

Duane Swing and I walked the gold box for the gear retraction system over to Wayne Lanza. His shop is in the hangar right next to the Velocity Builder Assistance Center. He found that one of the relays inside was fried. He kindly replaced it at no cost and we remounted the gold box. Again, you can only get this kind of quick resolution at the factory.

At that point, I had solved all of the issues I could solve for the time being and I headed home to Pennsylvania.

The folks at Aerocomposites called several days later to update me. They had the blades and confirmed that they had been machined with the shanks substantially oversized. They had them machined to the correct size, returned to Palm Beach Propeller, reassembled and delivered back to Velocity at no cost to me. I have to say that, although I was initially angry that I had the problem, I was impressed with the way they stood behind their product. All of this was done in a week and a half at no cost to me.

I got the call I had been waiting for from John Abraham on last Saturday. All of the repairs worked! As he put it, "It feels like a whole different airplane". The canard revision solved the mystery pitch issue and the prop worked great. The cruise at both 5,000 and 9,000 feet was just over 200 knots TAS. Like I said, I'm happy with any number starting with a "2" for my cruise speed. It is still in rough primer and no bolt hole covers. I think I can get a few more knots, especially if I add one electronic ignition.

Now the best news. The plane is working great and the hours are flown off. John is going to fly it up here and give me some dual time this Saturday. Finally, my airplane is ready to play with!

The bad news, I'm still not sure I'll be experienced enough in only 3 weeks to fly into Oshkosh. I'm going to play it by ear and see how it goes.

More to come this airplane homecoming weekend.
