No russ, this is the new one that i bought solely for the rb5.
I emailed Novak with the problem..... Heres there response, it may help others as well.
Hello Sir,
I see this problem all the time and it comes from two basic situations. The Most Common By FAR, is that the Battery Voltage is “dipping” to lower then what the RX works with. So the RX cuts in and out in and out when you mash the gas. Very very common with spectrum radios, and entry level FM stuff. But I’ve seen it with the High End RX/TX setups as well.
The fix is to lower gearing, or add a “receiver capacitor”. We sell one with a plug on it called the “glitch buster”, Spektrum sells one they call the “Receiver Filter Capacitor”. They both do the same thing, give the RX power when the voltage dips for that brief moment.
Next is that your Smart Stop has not been ‘programmed’. It has a button and needs to have the one touch setup done as well.
I will try messing with the smart stop first, and post the results,
Col.
