RE: OFFICAL RC18R THREAD
no .. i think its about umm transmitter and receiver ....
there is no need to upgrade unless you are having glitching problems, bad distance/range, or the old one broke ...
all JR and Specktrum stuff are good and have good rep...
if you are racing it would be worth it ... you do not need ALL THOSE memory functions...and stuff ...
IMO for your car its not worth the money ... since you arent racing or having problems with your stock one .
are you haveing problem with the stock radio ?
