Only with seperate cells you can use 7 of them. 6 on the bottom of the chassis and 1 (or 2 or 3) on top. BTW: Use , browse your image using the button and copy/paste the bulletin board code (the one with IMG between square brackets). |

Best change that side by side will fit best. Using the 3 in series in 2 rows is too long to put another cell in front of it (even more if the cells are longer than the normal 2/3 size). If you use then side by side, you'll probably also use a rubber strap to keep the batterypack in place. In that case, 6 on the chassis and one on top wouldn't be a problem (or 5 and 2 on top). |

@Tyrefryer: Did you apply the servo mount mod? There's a lot of wear on your drive shaft (underneat the antenna, above the LRP logo of the battery). |

With this information, I'm going to go ahead and list 7 cell as not supported stock in the Unofficial FAQ. Having to dremel that piece while as your picture shows using such banana connectors versus wire (I used those myself when I still ran ni-mh) is a bit much for many users. Also should add I believe there is a danger of creating a short with the metal spur since those tolerances are so tight. One bad shift.... Jaymac, have you considered just running 6 cell for the time being and maybe purchasing a 2 cell lipo setup for your next one (power to weight ratio, you would end up near the same speed). Thanks to all for the input for Jaymac (which in turn also has helped me). |

@ Sleurhutje: after my first ride with the MT, I noticed the problems with the drive shaft - so I cut off some of the server mount - also used my dremel to flatten the screws of the central servo arm (to solve ) @ Mini_Me: you are right with the short-circuit: there is only 1,5mm space between the battery bar & the spur gear |
