Sanwa M11 2.4 Issue

[knighthawk]

Hi Chaps

Posting this for my friend

He's just bought a secondhand Sanwa M11 Transmitter and wants to run it on his 2.4GHz Sanwa TX & RX Module

The problem is that it powers up, binds OK, works for about 20 secs and then the RX shuts down for 1 sec then powers back up and works OK for another 20 secs and repeats the cycle.

The Transmitter Module is TX-222FS
The Receiver is a RX-442FS

Is the transmitter not compatible with the 2.4 or is the transmitter faulty

Any help would be much appreciated
