I pretty much figured out the different TREX 450 models, but can't get "CDE". Stupid I know, but someone please fill me in???:confused:

are you asking what it stands for or what the differance is? its kinda like the trex 600 its not direct servo to swash. the servo goes through a bellcrank before its hits the swash. and i dont know what it stands for.

CDE is CCPM but is it with the plastic frame. HDE is with the linkages and arms.

Yes, CDE is CCPM, not direct servo to swash linkage.

HDE/CDE were sort of 'pre SE'. CDE is CCPM, but not direct links to the swash like the SE. CDE has lots of links like HDE, but CDE doesn't define servo 1 as aileron for example, the three simply work together in a mix to operate the swash. In HDE, a single servo is responsible for each induvidual channel.

Getting ready to buy the 450 SE V2 and keep seeing the CDE model on various websites, pretty sure what I want is the 450 SE V2. Have had a King 2 for several months and ready to upgrade. Good reports on the 450 SE V2.:)
