I agree 100% with your comments, Torque roll is great as are slow fly inverted spins, blender, waterfall. Elevator has bad wing rock, and the Harrier needs loads of right rudder...a scary amount. Likewise I have better Knife edge and Harrier planes. Its a great plane to fly, but I expect like most people I am in search for the perfect model. Actually I don't think it exists, so in the meantime I guess we just make the best of each model.
I also have my CofG at 6.25" and am running a Saito 100. Still a great plane
