I have a plane that I fly on fm. The tx is a 4 channel airtronics VG400. The rx was an airtronics 92777 and it says dual conversion narrow band fm72mhz.
Can I use a different brand rx? What do I have to know to make sure a different rx willwork with the tx? By the way its all blue plug Z connectors.

Thanks for any help in advance</p>
