Not happy Ive got the 7700 kv mamba motor and it doesnt seem reli fast only a tad faster than my 19 t Rocky There's something up with that! I just got 50mph today out of my MM7700. What batteries are you using? are you sure they are OK? Quote Link to comment Share on other sites More sharing options...

RobG Posted November 24, 2007 Share Posted November 24, 2007 (edited) All I can say is you should easily be able to tell the difference between a 19T and a MM7700 - they aren't even in the same league!! The MambaMax is also very amp thirsty so good batteries make a difference - but to be honest even on average batteries there should still be a big difference. Sorry I can't be of more help .

RobG Posted November 24, 2007 Share Posted November 24, 2007 no , youve been alot of help thanks So i need better batteires ? what do you run ? Well I pushed the boat out and got myself a 2S2P Lipo 8000 pack from MaxAmps. It was expensive (over £100 inc. delivery and tax charges) but worth it. For about 2 months I was running it on a IB 4200 stick pack which served its purpose. A MM7700 should still be impressive even on NMhi cells - so I can't garuntee getting a Lipo will solve your problem. Unless you think that your cells could be knackered? There are other people on this forum with more experience than me that might be able to offer you better advice. Rob Quote Link to comment Share on other sites More sharing options...
