CRT.5 Conversion (n00b warning)

[GO-RIDE.com]

If you keep your e-crt.5 really light a Mamba Max or even Sidewinder with a Mamba 4600 will run well. I have 2 e-crt.5s and one is really light and runs a Sidewinder and 4600 and it runs pretty darn well with a 12T or 13T pinion. If you go this route stay with the stock shocks, wheels and chassis, and look for a 2S 4000mah lipo soft pack as a future purchase.
