Feigao 9l warrior 7018 e-maxx

How heavy is your truck? Is it stock or does it have a bunch of aluminum on it. What I'd be concerned about is the motor. The 9L in a truck might get too hot. Many have gone to the 7XL for that reason, but the 7XL pulls more current.

I'm running an 8L in my relatively light buggy and haven't had any problems with heat. I like it better than running the 7XL because I find that it has more zip.

Taking a guess, I'd say that if your truck weights more than 10lbs or so, I'd say go with the XL motor and get an esc that can handle it. The Mamba Max does well on anything up to 4S lipo, or the nimh equivalent in voltage and they are inexpensive.

Its standard at the moment with mmg995 steering servo (nice) though i have a steel idler gear to go in, ali rear bulks,chassis brace, skids to go in. Also proline wheels and steering saver setup on the way. And a ubec on the way.

At the moment i have a novak ss5800 with 12/66 which runs suprisingliy well, if the new combo cant work i will try the novak with 7 cells which should be enough power and very light but temps will be a worry again.

Problem is thats already 2 brushless setups ive bought and the resale value will be very low if i need to change again.
