RE: hitec rx and fut tx compatable?
Hitec does not use high or low band like Futaba receivers do.
If it is marked Futaba (for negative shift) it will work with your transmitter.
Newer Hitec receivers are shift selectable with a jumper and the new Supreme are auto shift both will work with any major brand transmitter
Use a hitec crystal.
I use mostly Hitec receivers with my Futaba radio simply because they are lower cost and work just as good as Futaba.
