I'm just wondering how big a battery pack I'll need and where to put it to balance out with the 110FZ. I do have the right Tru-Turn spinner with the light backplate, so that will help some. Central is also sending one of those special pitch APC wide blade 3D props designed specifically for the 110. UPS says all the stuff including the 4/40 CF pushrod stock should be here tomorrow, sort of a two day early birthday present !
