i have a futaba pbj transmiter and would like to know what would work best for a receiver. i club race mostly indoor offroad with my b44.

What model futaba??
Is it am or fm?

Sorry it is a Futaba 3PJ FM transmitter with a futaba FP-TL-FM modul

Ok, you have 3 choices then.
1) HFS-03MT receiver which is single conversion. It takes a Hitec single conversion crystal in it.
2) DCX (negative shift version) receiver. This is a dual conversion receiver and takes a Hitec dual conversion crystal in it.
3) Synth DX. This is a synthesized receiver (does not use crystals). For club raceing this is probably the best choice since you dont have to carry extra frequency crystals around for it.

thank you very much for your time and your sugguestions the synth dx looks good to me
