is your slash class going to be a spec class ?
would like to now what the rules are for the class..the track i raced outdoors at had it pretty much stock, but allowed lipo, allowed oil changes , radio changes, and pretty much anything traxxas made as an upgrade. wheels and tires were stock only and now they will allow the new proline epic wheel and tire combo. they also went to a 21 turn trinity spec motor because it was rebuidable...speeds were jut a little better than stock motor..but runtime was a little better and the brushes lasted longer and of course are easily replaced.
