Lazer, Sorry to hear about your dog. The new girl looks good. I had a Sig 1/6 scale Cub. It had some nasty stalling/snapping tendencies and needed a lot of down trim to fly level when I first built it. Turns out I had built in too much positive incidence into the cabin where the wing mounts. I made some 1/8" shim plates and put them under the trailing edge of the wing. It trimmed out normal and tamed it's stall quite a bit. It still would drop a wing if stalled in a turn but that's normal cubiness. Try too shim the back of wing up a bit. It will require a more nose up flare before it stalls. I too would recommend a 12-4 prop even a 11-6 will help it slow down better to land than the 10-7 three blade. Looks like you are having fun with the old Flair Cub.
