if running a computer radio, make sure you dont have any unwanted mixes dialed in, such as rudder to aileron or aileron to elevator etc.

check thrust angel and mount


a guy at my field had a twist doing something along hte same line .. there was never a fix for it .. was just wone werid flying airplane

Does it happen to have any right thrust on the engine? That will do it. Right thrust is still a good thing overall. Shouldn't really climb, but if just banking won't drop as much. Now if it actually climbs, then I'd say you have right thrust and are tail heavy both.

That thing is a bit of a weird design, so it wont fly that clean and likely more sensitive to any improper adjustments or out of aligned surfaces.
Check the wing for warpage, sight down the tip toward the root, both sides, top and bottom,
Ailerons too, and tail surfaces.
make sure motor is not loosening on mounts.

He's right. If it tends to pull towards the canopy bad in knife edge then a partial roll might make it tend to go up a bit too.

another thing to check is aileron differential, some people have so much trim on their radios dialed in, because the linkages were not centered. This can give serious uneven deflection of ailerons.
Disconnect linkage and center the servos, then try to set the ailerons linkage so little sub trim on radio is needed to get neutral settings, Make sure servo is rotating same degrees in either direction.

Also check the rudder trim. My rudder was warped, so I thought it was right but wasn't. Mine done the same thing untill I trimmed out the rudder. The rudder is so effective on that plane that it will fly a little strange while out of trim. I also plan to try to warp mine back straight at some point by twisting it and heating the monokote, just haven't got around to trying it yet.

the real moral of the story is this just a funky flying airplane at best ... don't expect peferction out of it ..

but by all means run through the noraml set up senirarios just saying ... we had a whole club look over a twist 60 size and no one had a soultion that worked

I had some time on my hands, so I moved the elev and rudd servos to the front of the plane. There are already cut0outs there for servos. Then I was able to drop down to a 2650 mah battery which made it much lighter that the 5000 mah. This plane flies sooo much better now. Planning to convert it to a night flyer!
