Much thanks Othelo.I have a 14.8V 4S 6000HV maxamps battery.I have been searching all the forums online for the last month searching for all the info about the conversions available and I like the idea of the motor mounted to the center diff not like the other versions out there that go with the motor in the same place as the original nitro engine.RCproductdesigns battery box fit perfectly and really appreciate everyones help.I purchased a Losi 8ight T, mambamax with a bec, rcmonster engine mount ,rc productdesign battery tray and top diff plate.I currently have a NEU 15151.5d/f in the truggy now and its balistic fast I MEAN FAST.I am so stoked I decided to persue this project its new and differant and alot less hastle than my nitro XT8 although I will probably convert that also.
