Default Trimming Question

Hello all,

So now that I have my wing flying , I need to fine trim it since it is doing really sloppy rolls and loops.
There is a teqhnique something like ....pull a slow loop and see which wing drops?? Any help here is welcomed.

If its acting funny in rolls and loops, first thing I would do is check the control throws. Make sure the elevons go up the same amount and down the same amount with "elevator" input, and make sure they go the same amount with "aileron" input. If the problem is there, you should see it and either be able to mechanically sort it out, or if you have a computer radio, you can change the ATV for each control movement.

If the problem isnt in the throws, it could be a cg issue. Try moving the cg. I would go back in 1/8th inch increments until it gets a little "too sensative" then move it forward the the last spot it flew "right".

Any thing else after those two are done could be a warp or some other structural issue.

I may not be 100% text book correct on "my method" but it should work out for you. Just takes some time and testing is all.

Hope this helps.. let us know.

Ok. Just testing you Laine to see if you made it back from that last flight ok. Yes, I had 5 % aileron differential dialed in to the computer. I will remove it and test again in a bit here. Will let you know what I find.
