hello,
here is my problem i have just bought a X-400 pre built, when i turn the controller on every thing on the heli is leveled but when i push the stick up on the controller that controls the back and forth movement of the helicopter the helicopter does not go back into its normal position, which is almost perfectly horizontal, but when i push the stick back then it goes back into its normal position. its not the servo because when i let go of the stick the servo goes back to its normal position but not the main blades, could it be something with the building of the head.
sorry for the bad explanation.

It is a well documented problem with the x-400. The elevator arm is sloppy and needs a drop of ca glue (recommended by ark) to make a solid connection. if you hold the elevator arm and move the swash with your other hand for and aft you should be able to locate the sloppy connection. You will need to remove the screw that holds the two pieces together to see the problem. A better fix is to buy the 120 degree CCPM kit as that removes the elevator arm altogether.

ok i will try that today, because i tryed to lift the heli but it but a very crazy lift off, and is that 120 degree ccpm the best thing to do, where can i get it. also does the CCpm need any other upgrades needed.
thanks for your time

yes, it's 120 degree, and itll fix the sloppy elevator problem.

eccpm requires 3 HIGH QUALITY + MATCHED servos. if you dont have this, it wont work right. your TX must also be capable of supporting a 120 degree swash. you might be better off buying the metal lever and elevator system.

however it is the best upgrade for the x400 IMO

I have converted my X 400 to CCPM and used plain old H55's. It hovers hands off and flys better than my TRex CDE.

I flew it last night for the first time with my new Spectrum radio instead of my Eclipse 7 and no more glitch.

what upgrade is this CCPM or eCCPM [link]http://www.lichann.com.tw/rchtms/x400-ccpm.htm[/link]
