3rd flight on GP spacewalker I finally assembled, no fun in windy conditions ! I need advice what to about wing incidence issue when using saito 120, I have the ballooning problem others have experienced. I added 2 deg. downthrust on engine, still just does not feel right.

Plane setup is saito 120, throttle servo in engine compartment, upgraded to 440 linkage, pull pull rudder, balanced out about 4 inches , a little nose heavy. I wonder if I should use a smaller engine or change wing incidence? next question is if I change incedence should I move dowel location and have to deal with gap at front of wing or remove material out of saddle and move rear of wing up?

The 120 probably is an overkill but others have had to add so much weight up front and I sure hate to do that, and I had other plans for my saito 100. I know this can be a good flying plane but the way it is I'm sure not impressed with it. I'm much more impressed with my supersportster 60 and my Fontana 90. Any advice from others with more experience sure will be appreciated!
