I fly all my fuselages with the most common standard setups. You dont have to use any special or bigger battery packs or any special motors to fly my bodies. The fuselages are light weight and the fly really well on most standard 450 size helis and power systems.

As far as the A109 I do have one. I just put my Belt CP inside of one. I dont do retracts on many of my models, I myself try to keep it simple basically to show a person can still have a nice looking scale heli without investing alot of time and money. The landing gear on my 109 is fixed but the nose wheel does caster to allow for ground taxing .
