r/c on 35 and 40mhz in eu

not really.

In the UK...

All the digital (PCM) recievers only work with the same make transmitter, most the the analog PPM recievers are interchangable (but check thouroughty before take off!!) but to be honest if your looking to save a bit of money are you willing to risk yout model in the air?

PPM is digital too. Just different. A minor nit, but your older transmitters probably do say `digital proportional' on them. (Of course, to be fair, PCM is `more digital'.)

The real concern when mixing diffrent brands of transmitters and receivers is that the shifts won't match. But as far as a I know, this is only a concern in the US, and that outside of the US (or on the ham bands) all the shifts match, so PPM equipment is generally interchangable.

But I'm in the US, so I don't have much experience with stuff outside the US ...

Depending on how much `a bit' is, and how cheap his plane is, he may very well be willing to risk it. For a small foamie slope flyer, it's generally OK to have stuff that you're not completely sure works. For a giant scale turbine powered jet, no.

Ok Thanks, for start with rc aicraft I looking for all possibility which one work with other brands of electronic equipment. This is my first step with plane. I made plane looking coro spadet lc 40 but make with epoxy.

Thanks Realdo

Yup. If its PPM.

AM won't work with FM and PCM NBFM is distinct to each manufacturer.

No it isn't. Its multiplexed PWM.
