We only got 1 fight in at moto, due to a bent Ti shaft and no spare....and we were running on a 4 cel lipo pack. I nver got a chance to check amperage draw and actual drum speed

In anticipation of converting to a 15, I tached the drum with a 5 cel lipo pack and......40k rpm's and it keeps going higher....possibly over 500 fps tip speed!!!! and over 7k joules..not to mention that we have 3 pounds to add to the bot or drum....baaaaaaawaaaa....

this is going to be totally insane

Sting Em and It stings should be packing a heck of a punch at nat's....

btw: Stings little drum was only running at 33k at moto...and as the evnt wore on, it slowed down for unkown reasons.....never got a chance to do any motor or pulley change...it should reach close to 50k once fine tuned
