1) Disable and remove the gyro completely, so you can evaluate the aircraft itself with the absolute minimum standing between your finger inputs and the control surfaces.

2) Disable any slowing you might have on flaps

3) Triple-check that your expo is appropriate for the model and your flying preferences.

4) Triple-check the linkages

5) Triple-check that the throws are symmetrical. Consider applying a very gentle static load (a.k.a. 1lb beanbag) onto the ailerons to see if one of them skips or stutters.

Mach9's approach is correct --start methodically ruling out each element in the equation.

That the model fights itself to stay level sounds like a gain setting being too high. Too high of an aileron gain will typically exhibit itself in an oscillating, over-correcting back-and-forth movement. However, that this behavior seems to be happening in only one bank direction seems to imply an issue with the servo disadvantaged in that position to correct the model to level flight.

The Avanti is one of our most widely distributed and consistently popular flyers, so something is awry.

Hello, Anyone ever see an Avanti that has an un-commanded roll issue after initiating a right turn? Mine is new, and after right turn is initiated, then stopped, it will continue a descending right turn into terrain unless corrected, with the stick centered. It flys normally to the left. Flies great otherwise. All surfaces are neutral, flaps and gear up. With the gyro on it goes crazy trying to correct for level flight.

Thanks

+1, Avanti is crazy stable, never had an issue, no correction or gyro here.

I also cannot understand what is causing the strange flight characteristics, but would be money that the gyro is the cause and is not actually turning off. Either that or check that you do not have something unintended in a mix.

The Avanti S is definitely the smoothest and easiest EDF to fly. I do have the AR 636 3 axis gyro in but honestly, it really doesn't need it. If it banks left correctly, but not right, I think it can only be a gyro error giving the problems, otherwise it would do it in both directions. Put a standard receiver in and give it a shot. Alpha gives the best advice on how to determine what the issue is.

Talk about getting bored locked up in the house not being able to fly.

I don't mind avoiding people, cause basically I don't really like people, except of course if they share some of my passions which includes everyone here on the Squawk. So starting to run out of little fixes and modifications to my fleet, only left with finishing out the cockpit mods and repainting of the F-18 to the Canadian (which should get me through April). I finally got around to changing my canopy on my Red Avanti from a shaded canopy to a clear one. I know most like the shaded, but I did spend some time when I first got it building out the cockpit with pilots and instruments from Iflytally. After I put the shaded canopy on, you couldn't really see any of the work on the inside, so 3 months ago I ordered a clear canopy in the event I had absolutely nothing else to do. Well, it happened.

So here's my cockpit with the old shaded glass, and the new clear glass. Not sure which I like best, but at least I can see the work done on the inside (not that anyone at the field would ever notice-but I do).

This is the old, shaded canopy:

This is the new clear canopy:

Thanks for all the help with this issue!

I have the Eagle A3 Super 3 V2 Programmable 6-Axis Airplane Gyro

https://www.motionrc.com/collections...-airplane-gyro

I haven't touched it since the flights on Sunday. I also flew the e-flite Viper 6 times the same day, and love it. I thought about removing the gyro, and will when time allows, but I am an EDF Flyer in training, and this is not the airplane for me at the moment. I have no scale like flap deployment speed programmed in, or any mixes for that matter, as this airplane is not sorted by any means at the moment, so no fine tuning has taken place. It has been primarily flown by a guy who has 40 years, mainly flies EDFs, and very well I have to say. He told me to sell it, LOL.

I know it has an issue, and if I didn't deal with airplane/helicopter issues all day, 40 hours a week, I would jump on it!! But, I am in no big hurry to work on it when I get home from working on the real thing all day. I am somewhat interested in whats causing it, but not losing sleep, and I know it has to be a great airplane, its all I hear about. Plus several guys at my club have them, and love them. I like the idea of a small weight on the control surfaces, should provide decent feed back as to whats going on with a load across each surface.

Again, thanks to all the troubleshooters out there. Hard to troubleshoot without seeing the problem first hand. Been there MANY times.

I did a single place version using the clear canopy also. It weighs 4.4 ounces, no GIB. Made a glare shield from thin plastic sheet, and thin tubing for the padding on the edge. Also removed allot of foam, and allot of the Pilot internally with my die grinder equipped with a rotary file.

Very sorry. I posted on the wrong page. My bad. If I could delete I would.

OK, finished up getting the Avanti ready to fly, minus the gyro system. Weather here in Sacramento per the Saturday forecast looks really good. I will post the flight results. I made no other changes, One change at a time is the best approach to effective troubleshooting.
