rebuilding crt.5 need suggestions
 

I recently stole my Mamba max esc from my crt.5 to use in an e-maxx build, then I decided to sell the mamba max motor too. I was running it with a 7700kv on 2s because I had one left over from another car. Yes, it did get pretty hot (170's) So now I am going to rebuild with a new more appropriate brushless system. My main goal is to get this thing to an absolute maximum top speed. I have an e-maxx and hyper 7 for off road bashing etc, so I just want to see how fast I can get this to go. I was probably hitting 50mph with the 7700kv and 2s. I would like 70+. I was thinking maybe a velineon or xcelorin system maybe. But I am open to suggestions for any combo that is not super high priced. Here is what the car looked like with the mamba:

I will be using the Jaco 1/10 truck foams, because the stock rear buggy wheels just ballooned up way to much at top speed.

Hmmm, 70mph. I am going to go out on a limb and say that you will need some power to do this. Finnster had his crt.5 going pretty fast, check his threads as I can't remember the name of it...

I will say that you will need a high quality motor to get that kind of speed and decent temps. I would say that a neu 1506 on 4s lipo spinning around 50k rpm would do it. You would need a 3500 kv motor to do that. The velineon motor will not be powerful enough to do 70mph. Not sure about the losi system, but I do not think it will either. Maybe a 4500kv neu on good 3s lipo batteries would do it, but that may be pushing it. A mm would be a good esc for this, but you would want to disable the internal bec and run a ccbec to keep temps down, plus this is mandatory if you want to run more than 3s in the mm (and good to do over 2s lipo IMO.)

Yea try this out I have a Neu 1515/1d/s a Quark competition 80b an 3s 11.1v 6000 lipo battery and lets just say it has never overheated the ESC motor or battery.Its overkill yea but I just couldnt resist.This little truck has the extended ofna chassis and a custom made 4mm grafite top diff plate.Its a rocket now I can imagine if I geared it up it would have a impresive top speed.This truck is my all time favorite rc car its just a real blast to drive.:diablo:

Would a 7L be a good choice? Does anyone know what the Xcelorin's are most similar to?
