Dennis,

9C - very cool. Taking me some time to really exploit the features.

Muffler Tunnel - clears lots of 2 stroke mufflers, but maybe not Foster Beer cans LOL.

Controls - very neutral with little cross coupling. Knife edge is rather easy and does great both sides.

Pattern or 3D - the Freestyle is unusual in that it is capable of both. Landings do not require high speeds. Mine is just rock solid to land, and can be landed very slowly. It will do all pattern stuff, and most 3D. Pretty unusual to have a "hybrid" plane such as this to be capable of doing both nicely.

Pop-Ups into a Harrier - my plane would snap out of a popup into a harrier if programmed stock. But, if you add some reflex (up aileron) with up elevator, it actually mushes around nicely. My IMAC buddy helped me set up this plane. We added 60% up aileron with up elevator input to increase washout. I have it programmed into the up position of the 3 position switch on the right front face of the 9C.
