Once you get an acceptable range check with a PPM/FM receiver and with the engine running, now you can go back to the PCM and recheck the range.
It's worth the $60 (Hitec Supreme 8 channel FM) to keep one of these around just for checking out you plane, even if you never fly with it.

very informative tom & thankx, just so happens this is the way i built my 1st gasser, but it was due to lack of funds... started with DA50 & ppm/FM with 645's then went to 5945's with pcm receiver of course.
in a case such as this can one use the 5945's & 5955 on a fm receiver? just to get a good inital range check before installing the pcm rec.
