I am currently thinking of doing a F.o.c conversion and was wondering if this http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXCNA8&P=7 would fit. I have a .15 pro chassis, and was wondering if there was a different one for this and the 2.5. Also What are the benefits of a FOC?? And set backs?? Thanks again everyone, your help is VERY much appriciated. (I turn to RCNT for all my Bashin needs and you guys havnt steered me wrong yet, BIG PROPS!)
