Not on Lipo, using some old Batt 4000's untill my Corally 42's turn up. I'm geared at 20 84 with a Losi 6.5t i think all the Losi's are sintered. It felt very soft if you know what i mean, but i had been practicing earlier in the day with my Corally on roader with a 3.5t so its all relative.......
The Motor was pretty cool compared to my TC after a run, just worried about runtime at Worksop but after the 6 laps of practice and a 7 minute final without dumping i could be worried for nothing.
