It looks like the crank pin overheated.... low oil or extremely lean free rev situation. I would stay away from nitrotane, Horizons venture in the White LIghtning fuel didnt work and I would guess the Losi fuel is very similar. I run all sidewinder in my Vspecs.... I rced the Futaba challenge last year, threw my car in the garage when I got back....didnt touch it for 4 months and raced the Phycho Blast in atlanta with zero issues... sidewinder and OS is a dead reliable combo IMO.
wassup Art? Almost time for some sunshine and nitro
