I have a low wing aircraft that had a poor roll-rate.
I re-engined it with an OS FS-91 IIP which was a bit lighter than the original Laser 91. The CG moved aft a little. The roll-response was much improved.
So, it may be that your CG position is well forward. This causes a higher angle of attack (because the tail is producing down-thrust) and modifies the airflow over the ailerons, making them less effective.

Thanks for all the advice I think some of the problem is the ailerons move more down than up. Everything else seems fine, CG included. I did convert it to a taildragger but that shouldn't really matter.
Here is a pic if anyone sees something out of the ordinary.

Thanks

The only thing I see that's out of the ordinary is you still have your Christmas tree up...

Other than that, all looks normal to me.

When the manual says "1/4 inch throw", well, I add a little more to that then use expo on my transmitter.

CGr.

ha ha ha or should i say HO HO HO! the pic was taken about a wek before Christmas.

I built it with all the throw I can get
