On my 1000 I decided to go with the 120AX instead of my 160FX. The 120 is no slouch and it is an easier fit. The added benefit is the ability to run 14 to 15" props which will allow me to build it with trike gear. For some reason I always preferred the look of trike gear on this design. That and I haven't had a plane with trike gear in more years than I care to remember.
