Hello,
Hello,
Personally, it's going to be difficult and must be at a 27 MHz frequency. Personally, I would replace the whole thing with a Heng Long or Taigen system at 2.4 GHz. Attached is a complete receiver, transmitter, and speaker set for a good price. There will certainly be some wiring to redo, but no more than with the old board. It's up to you.
