OK. I am back from Mentone. I had a great time flying Lucky Lady. She performed flawlessly. I was concerned for Terry I. as he had 2 deadstick landing in two different Sparrowhawks. Just one and I would have peed my pants. Two and I would have done much worse in the undies.He seemed unaffected as he got right in and continued to fly the whole time.Then again, he may have needed a change of undies. I didn't ask.
I put about 5 hours in my machine and had a great time with the other RAF owners. The dominant aircraft flying was the RAF. Most had stabs or a stabalator. The next most popular flying machine was the Sparrowhawk. These two designs used up the $2.85 per gallon gas.We would fly to an airport about 10 miles away for breakfast every morning.We landed on a grass field across from the restaurant that had the biggest breakfast I ever saw for the $.Everyone was so helpful out there. Pat McNear was in the air constantly, but not to busy to help take rotors off and on. One fellow from Maryland(I apologise for forgetting your name) came to the rescure with his new crane system that hooked right into the hitch of his truck. Thank you for the help and please e-mail me your address.it was great to see Stan Foster. He flew in from Illionois, about 120 miles away from Mentone. I was most disapointed in a CFI that promised to give me a check ride to file my 8710 to get it in before August 31. I saw him Friday and he said he would be around Sat to go with me on a checkride. I never saw him on Saturaday and Andy and I were leaving by Sat noon. I hauled my gyro out to Mentone to participate but the main reason was to get the checkride in my own machine.To put it another way. It sucks!
On to the original topic. I have put 2 more hours in on the modified RAF. Here are the results of a few tests I have performed now that I have it trimmed. The power is breathtaking with the new fuel injected cammed up EJ-22. I am now doing full power takeoffs. I need a lot of right rudder and left stick to handle the torque. I have it trimmed for 70 mph and the climb rate is awsome. I pull it back to 60 mph and it is scarry. It climbs like a homesick angel. I did one full power climb and I pulled power to see the result. No pitchup and it settled into a 70 MPH glide.No stick input.Add power and it climbs at 70. Cut power and it descends at 70.Nice!In 5-10 with no gusts it is somewhat boring. It just goes where you tell it to with the stick and then forget it. No more stick inputs to stay the course. Sit back and enjoy the ride.
When Landing , it does not seem to flair as easily as the un modified RAF.Not sure why. Any thoughts on that? I have not made a 0 forward speed full stop.( I have tried) It wants to float through what would produce a 0 feet forward landing in the old RAF with the LM stab.It wants to land like an airplane and have a small ground roll is the best way I can explain it.It is truely a joy to fly. I would like someone with RAF gyro experience to test fly it and give me their opinion. Even though I don't want to be biased on my comments and I don't think I am, It would be good to have another RAF pilot opinion.If it is what I perceive it to be, this could be the poorman's fix for the RAF or another way of saying it,this could be the answer for someone who is a low time gyro pilot who wants to fly a potentially more stable 2 place enclosed machine, but feels the RAF might be a handfull for a low time pilot.Once another pilot flies this and verifys my results to be accurate, I will make availabe to the RAF community the list of materials and a detailed account of how to make the conversion in a weekend.I hope this project puts to rest the RAF issues and if it saves a low time pilots life, then My efforts will have been worth it.Udi, thanks for your comments.

Great Mentone report! Thanks!

Sorry to hear about missing the check ride.

I thought Rochester was closed. Did you land on the taxi way?

Tim: Everyone was using 11 or 29 taxi way at Rochester.

Larry, You should of had Pat McNear fly your RAF, while you and he was there at the sametime and place. After all he sure could of gave you some insight, course only his but still I would of asked him if it was me.

Sorry about the Check Ride, that CFI needs to understand how Important that was to you.

Great write up on Mentone thanks for taking the time to enlighten us.

Glad to see your machine is working out for you. Congrats on your mod. :D

Would also be interested in some close up pics of the mod...and in your offer of the mod details.

If you were close by, I'd be happy to fly it and give you my evaluation. ;)


Cheers :)

Rotornut. I had Lucky Lady out to mentone, not the new modified RAF. I have to fly off 40 hours on it befor it gets to travel. I hope to have it at ROC where I hope to have someone lined up with lots of RAF experience to fly it and evaluate the changes.

Larry - I knew you would like your modified RAF, as you had lots of experience with your old CLT Air Command. I would like to see someone coming out with a kit for doing the mods you did. Your mods are not as extensive as the AAI kit, but I think your gyro now is very safe and these mods are much easier to do and cheaper than the AAI kit.

Larry: Udi is saying the same thing I told you at Mentone. You need to market that as a kit. From what I saw of it...it looked very stylish....and the hours involved that you had were not that much. Of course any lowering of the thrustline is another plus.

I agree with Stan, market the kit as turning the RAF into a 'Boyer' or whatever! That way the RAF designation gets replaced with another name than doesn't carry baggage.

If you can get the independent verification of performance that you want then I would say that you have made as big a difference, if not more, in the RAF2000 as Ken Brock did in the Bensen. And he marketed his machine as a 'Brock' with different model numbers.

I will be flying tomorrow morning as my secretary gave me the morn off. I'll take some detailed pictures for the gang. I had not given much thought to the commercial end of this. Only want to help the RAF be the best it can be.(sounds like a canned slogan from somewhere don't it?)Anyway I would like to hear from anyone who would consider a mod change if it really turns out to be a major improvement like I perceive it to be. You can E-MAIL me at LARDEBBOYER@aol.com.

Wednesday evening it was under 5 with a gust occasionally to 10. I wanted to leave the airport and go out over some fields to do some tests.i climbed to 1500 ft. ihad it trimed for 70 and it stayed there. I abruply pulled throttle to see what a full power climb and loss of power would do to the attitude changes.. it just dropped the nose and descended at 70 mph. I added throttle to 4600 rpm and wanted to see what would happen. The gyro leveled out and started a cruise at 75. i slowed the engine to 4200 and left go of the stick. Steady as a rock. I pulled the stick back and the left go. The gyro pitched up and the leveled out to the 70 mph cruise. I pushed forward and left go of the stick. It returned to straight and normal 70 mph flight.Iput it into a turn with the stick. it stayed in the turn. I thought, this is like flying an airplane. i am now apsolutely convinced that the keel modification and a good stab will give the RAF owner a safer and better flying stable platform.
As reported earlier, the stab being further back by 10 inches and the closer CLT does not allow the aircraft to flair as quickly as the unstabbed or conventional stab setup. I can't seem to nail a o forward stop landing yet.Wind will help.
The aircraft flies hands off in straifgt and level flight. I have a slight trim problem. Ineed to redo my adjustable trim tensions. It has a tendacy to favor stick pressure to the left and I have the yaw wheel to the stops. I will work on that. I raised both springs on the chain trim, and that was the wrong thing to do.On take off I needed hard right stick and hard forward stik at the same time to keep it on the right course. I am guessing I need more legnth on the chain. Any comments?

....to the much improved Raf flight regime that we have been experiencing for a few years now. Your report is music to my ears. :D Ain't it great???? ;)

Now you can appreciate what all my excitement was about a few years ago!!!!!!!!!!!

Paul, good to hear from you!. Any thoughts on running out of trim? Should I lengthin the chain?I need more trim to the left.Am I to tight on the spring and chain now?

Photos PLEASE!!!! You're makin' me want a RAF again. I had resolved myself to the ranks of future Sparrowhawk owner till hearing of your mod. (Not that that is a bad thing, just more expensive.)
