Just got this used m11 and it's a headache! First the Rx was blown and now my range is supper low. When the sc truck gets 2-3 car lengths away it stops and I get no steering or throttle. As I walk closer the MMM re-sets then the sc works till it gets a few feet away. Havent owned a m11 so I'm not sure of the ranges with low or high batter volts. The first set of AA batteries said 9.1 and it was beeping to let me know that's too low. Then I put my back up batteries semi new and it said 10.5. The first set gave me no distance and the second gave me a tad further. No sure if the MMM is going out because of the re setting or if I have a faulty radio or Rx. Don't want to invest into a m11 lipo until im sure it's ok. Using a dsss module and Rx now and i have a spektrum module on the way. Hope that fixes the issue but if not what else should I try? Not gonna try it on my nitro because last thing I need right now is a run away buggy. Any suggestions? Thanks
