Help with a Lehner Brushless Supermaxx

Im very happy to announce that it works fine on 12 cells. I got a couple of wheelies out of it, which is pretty good considering the weight and soft suspension. It will certainly be better on 18. I love the car :) Vry fast acceleration in 1st lol. Could only use 2nd for like 1 or 2 seconds outside my house. London is busy city still at 1 am lol.

Thanks all very much for your help, now i need to get a charger for 18 cells...
