I have completed the install to a comp-arf flash. I have used two 2100mah lipo's, a powerbox sensor,Rx is a JR10DS witha graupner whip aerial, mounted like many people have halfway down the fuz, and I use a JR PCM9 as a TX. I am getting 40yds range with the fully charged lipo's but 48yds range with a single 4.8v NIMH that I half tried it with. I also notice that the range drops off to only 25yds if the lipo's get partly discharged. Is this acceptable and why is the NIMH producing a better range. I would add the ranges are the same for engine off or on but if I take the RX out of the model ( with whip aeria)l and test it with a single servo and the NIMH battery then the range is 80yds.
