Mamba Max 5700 in my T2

[GeeReg]

Just thought I would start off the new subforum. This thing on 3s is amazing. I went from 8 cells to 3s and it's not even close. You can lift the front end at any speed up to almost top speed just by squeezing the trigger. It's very dangerous if you're not careful.

Anyway, I have no idea how to gear something like this other than trial and error. Right now I'm running 84/17 with the T2's 2.6 tranny and Speed Hawgs and I GPS'd it at 52. Everything gets hot after a few minutes but I'm not sure if that's just the voltage.

Every now and then it will cut out though and I'm not sure what that is. For example, I'll take off and ease into full throttle, and it will cut out for a second then kick back in. The only thing I've heard is this, which doesn't apply because it's about 4s:

BEC on 4s:
The BEC is a linear regulator, meaning it's taking the battery pack voltage and knocking it down to 5v for the radio system. This "knocking down" of the voltage has a price: the higher the voltage, the more heat the linear regulator chip has to vent off in order to get it down to 5v. Now the chip itself is in no danger - it's designed to thermally shut down (provide no voltage to the radio), cool off (takes about a 20th of a second) and come right back on if things are out of whack. Or even continually cycle in "shut down and come back on" mode if things are REALLY bad with no damage. The issue is obvious - each shutdown is turning off power to the Rx and servo (bad thing) and can look like anything from just a glitch, to totally erratic radio behavior, so the car may be undrivable immediately, or may become so at any time if you haven't disabled that circuit when using 4s. (Again - not covered under warranty and beyond spec at this time!)
