Jordan, I almost forgot...welcome to the forums!:yes::mdr:

Thanks, looking forward to finding good info and building a durable fast car.
What do you think about the MMM CM2650 combo, I know it's overkill and that fine but I was looking at a NEU 1512 1Y or 2D and after you buy the ESC the combo would be cheaper.

The 1512 is way over kill in a crt.5 IMO...although some members run it. I am running a 50 series Medusa on 2& 3s and it goes pretty well.. A mm esc w/ a 3s 3300 Medussa will push the truck to 43 mph. The Medusa motors are v/good motors and half the price of the Neu's

I thought about that but if it does turn out to be too much overkill I'll put it in another conversion but would it fit? and do you think 5S or 6S (1P) A123 would be enough?

I believe it would fit...like I said someone here is running a 1512 in a crt.5. Gearing will be limited though...Mounting the batt and esc will be tricky, but, it could be done. Your set up probably wouldn't fit in a stock chassis...Mike's chassis is 40mm longer. And his new one, when it's avail., is a tad longer than that.

Well I was planning on building one based on the ext chassis, if i can't get a hold of an older one ill just get the new one.
Thanks for the input, Jordan
