I moved this to Futaba support for lack of a better place. There doesn't seem to be a generic radio forum that has posts in it??? If there is, would you please move it there Bax? Thanks.

Anyway, in Europe all radios use positive shift, therefore as long as both the transmitter and receiver are on the same channels, they should work together.

As far as the servos plugging into the receiver, you need to be careful. Most modern receivers are pin-compatible with each other, and the servos will work just fine. Make sure that the center pin on the receiver's servo plugs are the positive pins. I've never heard of a Webra receiver, so I don't know how old it is or anything like that unfortunately.
