Barry,

Wait until you get this thing into a fast KE spin. It winds up really tight.

A hint about coming out of a any type of spin on a Cap. Give it a quick blip of opposite rudder. It will feel unusual at first but rotation stops almost instantly (about 1/4 turn). You can then power out inverted one you get the timing right so that you can stop the rotation right where you want it

Did you try an inverted harrier. I did my first one on this plane the other night and have seen whaturi do them on his. Inverted is super stable.

I think one of the best things about landing this thing on grass is watching the mains touch down and absorb the little bumps while keeping it planted on the ground, looks so cool
