Axial yeti kit xl speed runs. Managed to achieve a top speed of 49mph. I know I can get more out of it. Just need more run time and a few suspension adjustments. It sure is a hand full on 6s. The front wheel goes up as soon as I go full throttle. It's unique suspension layout makes for interesting and sketchy speed runs. In the end my son and I enjoyed running the YETI XL on 6s. Time to take it to the dirt!
