Looking for some help

I am trying to upgrade my radio to a dx7 for my cp pro and having so trouble.

I can't get the heli to spool up and I am not sure what to do

Everything else works except the throttle and rudder

Any help would be appreciated.

Re: cp pro and dx7

It sounds like the three in one board is the issue. If I'm not mistaken E-Flite has published lots on the conversion to Spectrum radios in their instruction manuals. I did a gyro upgrade on a CP Pro for a friend and it worked well according to their instructions. Failing that, make sure the trim is all of the way down on the throttle channel to arm the three and one board. If you can add a heading hold gyro to the CP Pro it makes a huge differance. If the three in one worked before, go back in your setup to where it works and start again from there. Change one thing at a time and record what you did. If it does not work post the issues maybe someone has seen the issue before.
