CDE/HDE Differences
 

hey guys

just a quick question, whats the difference between the trex 450XL HDE and CDE kits?

ive looked and cant find anything explaining it. im looking at one for my next heli.

HDE uses separate servos for pitch, roll and collective.
CDE uses all 3 servos for all 3 functions (CCPM)

Yeah, CDE works like a traditional helicopter's swash plate. It uses 3 servos spaced 120 degrees apart to manipulate the swash plate (collective up/down, for/aft pitch, and left/right pitch). HDE is what the shogun/dragonfly35 use. One servo for collective (through the mast), another for for/aft pitch, and another for left/right. CDE is much better but you have to make sure you xmitter supports 120 mixing.
