mx sport receivers look to be it. i think they around $50 which is comparable to futaba fhss receievers. not bad at all.
could be worse, my "Value" Receiver is 92744 at $89-$99 lol. next one from that, 92451R at $120, and my RX471 "i have only two" at $139 lol...... ...
just mount the rx in such a way its easy to change i guess. i did it in my 12th to touring car and back in same nights racing.
