?'s on setup

[MetalMan]

The Mamba Max ESC can comfortably handle 4s Lipo (14.8v), and some have had luck with 5s Lipo. 6s Lipo would be too much.

The 8XL on 4s Lipo would be fine. If you wanted to run 6s, the 9XL or 10XL would be a better choice.

For 30-40mins., 8000mah is a minimum IMO.

For a cheap/decent radio system, I use a MX3-S. I got mine brand new for $96 since it was on sale and my employee discount was thrown on top of that. You can get regular (non-synthesized) MX3 radios for about $105.
