What kinds of planes need 5 cell packs, or; how will I know if I need a 5 cell pack without crashing first?
Well, it ain’t quite as bad as all that; folks have been flying with happy smiles for several decades on 4 cell packs; and certainly not everybody needs one. On the other hand, ‘standard size’ 120oz pack draining high torque servo’s haven’t been around for decades. Ever more apparent the past couple of years are aircraft and control systems that ‘ol Gramps and his Kaydett would hardly recognize. The demands of modern aircraft designs with massive control surfaces tied to ultra high speed, high torque servos forces a better, higher capacity, higher voltage pack to keep up with the higher loads without the risk of tripping over the minimum voltage the receiver needs to keep you flying. Pattern Planes, Giant Scale, Aerobatic, Heli’s, 3-D’ers and anybody else that wants faster control response and more servo output power should be using a 5 cell 6 volt Rx pack.
