I know the aftermarket Mfg. love this truck they seem to be on it like a traxxas. I have not seen this many chassis since the T MAXX.
Losi has so many options for the truck I sure do miss the days of the Team losi XXX BK or MF series where you did not want anything for the truck.
I have a truck out of the first batch and have the original rear bumper and chassis. I wish that the motor mount would give a little more gearing options. Stock mount goes from 11t to 20t. The RTR motor seems to need a little more gear to be competitive on a big track. The Elite motor has the opposite problem and goes from a 14t to either 25 or 26 tooth. I ran a Castle 1512 2650 on 2 cells and it hauled with a 25.
Have you noticed the MIP chassis flipped the front and rear center driveshafts to give a better angle to the front driveshaft like the King HeadZ.
