Hi everybody,
I've red on that forum a lot of very good suggestions for all the electronic parts. I've also used the ABC CRP Unit in 27 FM. This unit looked to be very practical because all in one, but it's true that it's not working propely. I know the reason as I've made several tests on it. This unit is produced by KOPROPO for ABC Hobby. I'm using a Multiplex Profi 707 Transmitter and when I've tried the CRP for the 1st time it was a nightmare. I also own a Futaba and with it the problems bacame minors (glitching...).
One of my friend own a KOPRO EX-1 and came with to me. With KO Transmitters, the CRP is really working fine as you can expect.
As it's cheaper tpo change the electronic than the transmmitter, I took the CRP Unit away!
