RE: Do all gas engine planes require 4 channels?
Jeepster got it right! you can save lots of cash by finding a club and instructor. A good instructor can teach you things about tuning your engine, preflights, what to look for on your plane etc. Talk to some club members BEFORE you by your equipment, it may make things easier and save lots of heart ache. And there is lots of knoledge on this site to help as well.[sm=biggrin.gif]
