Great to hear Brian. This means its really close to all the other Oxai models we have flown. It should be about 1/16" of up trim.

The question is how are the up and down lines. Its pulling I bet a touch in both. Slowly shift your CG aft just a little until the upline is dead on. When this happens you will be at the best CG point. Now look at downlines and it will likely pull very slight. A small throttle to down elevator will take care of this. If you want it to be a little more aft CG then you can shift it back a bit more and the pull on the downline will go away also. I feel the models track better more forward CG than Aft. So I compromise with the mix in the downline. You should be about zero for knife edge mixing and CG really doesn't play a role in this model unless its really far out of whack. I flew one really tail heavy and it started pitching belly but that was when it was hands off inverted. Not very easy to fly a model this way. Some will choose this setup but I think its tough on the pilot. The suggested CG is like 175mm aft of the LE at the fuse side for the one piece wing model. My Pinnacles are at 180mm and 182mm aft of the LE at the fuse side. This was eliminate the slight pull on the uplines...Both have near no mix for elevator and zero for aileron with rudder input. In my two models one model has a 2% up mix with like left rudder and nothing on right and the other model is zero elevator on both sides. This is knife edge looping rudder input gets the 2% mix.

Next thing is as you shift the CG back the up trim needed will be reduced. Once its dead nuts straight up and slight pull down, then dial the stab a little negative and fly it. You will be taking some of that up trim out...But get the upline right first....

It might take a full turn on the adjuster. Remember this adjuster is on the bottom of the rear tube. SOOOO clockwise on the screw will lower the rear tube or give positive in the stab and CCW will raise the rear tube and reduce the incidence on the tail.

All of the Oxai models I have seen fly or flown myself have been in the same state. This is all the trim that I have found needed. One had a little wing tip weight added....but the others this is about it for adjustment. I usually dial the wings a little more positive on the Pinnacle as this reduces the up trim also and raises the tail in flight. On the one piece wing model you don't have this option but dialing the stab will do the same thing. All the angles are relative...So negative in the stab is the same as positive in the wing.

Obviously you got the differential close from our conversation on the phone. I hope the throws were not too far off. As I said my setup is a little hotter than what you might need for Intermediate but its a baseline. I know my throws will yield good snaps, and spins without switching flight modes.

Let me know if there is anymore I can do to help. These things really fly well.
