OK I am about to put my head through a :arggg:. I went and purchased the Spectrum DX7 radio kit with the 3 servos. Well i went through and installed them and am now having a heck of a time of getting them to move all in the right direction.

I have watched the CCPM 1 and 2 videos but for the life I me I can't get it to work on this bird. Now my buddy just purchased the EXI kit and same radio unit and we where able to set that up in the space of 5 minutes (with the video help of course).

I am trying to get this all to work with the Belt CP frame as I just purchased a cnc head unit for the Belt from cnchelicopter so that was $80+ dollars that I don't just want to throw away if I can help it. :roll:

Eventually I will get the EXI frame kit and have a mainstream frame to work with but for now I would settle for any assistance anyone can give me to get the servos all moving in the right direction so I can get this bird up on the air.

Thank you all in advance for your help it is greatly appreciated! :noteworthy

Don't worry too much about getting them to move in the right direction, just get them all to move in the same direction. Once this is done, if they are moving in the wrong direction, just alter your swash mix pit setting from +ve to -ve or vice versa to achieve the correct direction of travel.

Tell us what is happening now and we can probably help you out.
I had the same set up on my belt until I sold it and have set up both of the
Trex's without to many issues, I am sure it can be done we just need a little more info
What do the servos do when you
1. push the throttle up( motor disconnected of course)
2. Give left cyclic
3. Give right cyclic.
4. Give up cyclic.
5. gve down cyclic.

Once you get them all moving in the same direction as sutty said you can then adjust in the swash mix.
Tell us what it is doing.

thank you guys for the info. I believe I got it all worked out. I took your advice and got them all moving the same direction and from there it was pretty easy. I was just focusing on reversing either pit. or ali. but what did the trick was reversing in the swash mix the elev.

I think the problem really was I was trying to set this up on only 3hrs of sleep. :shock:

Once again thank you all for your help! :noteworthy
