A further-forward c.of g. might also help---but of course this can squeeze the balloon somewhere else.
I've got 2 fences on the stab, perhaps 4 would be better.

Yes lower angle of attack would help. Higher velocity and a larger radius.
pd 1:
Yes in a pull the descending blade which is on the right (looking forward) has a higher angle of attack than the one on the left so that causes a yaw to the left and that is what I am experiencing.

My Jeti transmitter provides a 13 point servo balancer on all servos, so my elevators are matched perfectly. The plane had a bowed aileron that I fixed as well as I could but I still carry a little right aileron trim. That could contribute.
Then again it could be the pilot. I think I'll take a Contra plane out and see what it does.
