Strat I'm using a 7CHP with the stock Rx and it works flawlessly. I had to switch to PPM though. In PCM it didn't work at all.

Switching to PPM is easy. Here's what I found for the 6EXH.


To select modulation:
1. Access the Model Select function in the programming mode (by pressing the MODE and
SELECT keys simultaneously and holding them down for one second). Use the DATA
INPUT lever to select the model memory you wish to modulation select.

2. Push SELECT key twice after seeing on the screen the model memory where you want to
set modulation, then you will see “PULS” on the screen.

3. To select PCM modulation, push the DATA INPUT lever up. The “PCM” is displayed. To
select PPM modulation, push the DATA INPUT lever down. The “PPM” is displayed.

4. To get the transmitter to operate in the new mode, switch transmitter power off and then on.
The small indicator will indicate the mode, either PPM or PCM.
