RE: HI-TEC channels different than FUTABA rx ?
The receivers would be the same even though the nomenclature may be different. You can use Futaba Transmitters with Hitec receivers. Just ignore the nomenclature of the Hitec and use the nomenclature that applies to the Futaba Tx.
If you use Futaba RX with a Hitec Tx, then ignore the Futaba RX nomenclature and use the nomenclature for the Hitec Tx.
