Bob, I flew my Swallow with CG 165 mm back from LE at fuselage, and it handled very well at that point. I did try a bit further back, since some guys recommended back as far as 180 mm, but for me that gave too sensitive an elevator. There are a lot of guys that like a two-stroke 1.20 on this plane, but a piped 90 should offer ample power. The 25% CG recommendation is not to be taken seriously.

It's not the wrong plane, so don't sell it. Swallow flies beautifully. I crashed mine in a moment of distraction, but got another and looking forward to putting it up again.

I hope you're setting up low rates on elevator. I had trouble getting smooth landings at first, had to reduce elevator throws twice, add expo and move CG forward before it would behave well on landing. Elevator was at +/- 9˚ when I was finally happy with it.

I will not have computer access for a few weeks, so further questions will have to be answered by others. Good luck with your plane, it's definitely a keeper.
