Well, I got 6 more flights in today and I am getting very happy. The little bit of downthrust I put in cured the vertical upline going to the canopy. And I played a little more with CG and control throws. I liked the CG a little further forward then the last series of flights. And I've been reducing the normal control throws. The big one was cutting the rudder throw way down. The rudder is very powerful on this model. Right now I am using 5 flight modes. A normal, a spins, a snaps, one for stall turns and then one for landing. The landing mode just turns off the throttle/elevator mix I have for downlines. And with the spin one I enter in the spin mode, then just as it breaks I go back to the normal mode. BTW, the spins are now very good. It also seemed to roll better with no differential. I had been using just 4% but zero seemed better.

Increasing the downthrust is something I have seen a lot with models that are designed for both glow and electric. If you think about it, a glow model has a lot of weight very low in the model. The engine cyclinder and the exhaust system. When I first starting flying my Partner back in 2004 it also pulled to the canopy slightly. But the way the Partner was done I could lower the motor batteries in the fuselage a lot, moving the vertical CG down and that solved the pull. With the Onas it needed just a bit more downthrust.

I sure do enjoy working these things out! Some times trimming can get a bit frustrating, but when it all starts coming together it is very satisfying.

To answer an earlier question, I have always felt that the LE of the wing needed to be very solid. No vertical wiggling at all. The way the Onas comes it has rear adjusters and a front pin. You are supposed to fly it some, get happy with the incidence and then install a donut in the fuse to engage the front pin. I put in front adjusters so that I could get the front of the wing solid and still be able to change the incidence. Certainly not needed for everyone, just something I like to have in the model.
