More 21.5 testing went on over the weekend in USGT and F1.
Bottom end is amazing!!
In USGT we ran 25* endbell timing with a 52-96 with 1.9 drive train.
In F1 we ran 25* also, but at a 36-96 with Tamiya rubber tires.
For those of you who just ordered 17.5's, they are being built now and will be shipped out today!
