Sweet!

Sounds like you had fun. My son and I both have Maxx's but they're not race ready for our track, yet.

Unfortunately for our mains we need to run 30 minutes so getting just the right setup is important. It's either fast pit stops or large capacity batteries.

The EXT upgrade still looks good w/ the stock body. What kind of rear drive shaft you using? I've considered the EXT as an upgrade option just for better placement of the 18120. I think I've got it the way I like it w/ the stock g-maxx chassis.
