OFNA GT-V2e out of box review on 4s 2x Track 5600mah 60c lipos. 28mph was as fast as I could get it. It might have 30mph in it but it was hard to control on my street mainly due to the tires I think. I'll be switching to Mamba Monster and 2200kv or 2650kv on 6s with a 25t pinion for the next run, with a Savox 1258 servo. Stay Tuned! Subscribe! All Thumbs up please!
