200A, 14S lipos ESC to come!!!

[snellemin]

sweet deal man. The mamba does great with low kv motors, but I have the same issue like you when I use my 7800kV LRP.

I'm also going to have some Brushless ESC for 1/18, 1/16 and 1/14 scale. This little guy has the following Specs:

Specifications:

40 Amps maximum continuous current rating (at 25℃ ambient temperature with proper air flow)
Input: 5~18 cell Nixx or 2~7S A123 or 2~6S Lixx
2 Amps BEC (maximum input with BEC limited to 9 cell Nixx or 3S A123 or 3S Lixx)
Dimensions: 40 X 24 X 14 mm
Weight: 23g (including leads)

Features:

Proportional forward, brake and reverse
Proportional control of starting torque by throttle trigger – the starting
torque can be tremendous high or incredibly low
Extremely smooth startup and low speed operations
Programmable throttle curve, acceleration rate, motor timing, low
battery cutoff voltage, reverse power limit and drag brake strength
Easy and fast stick programming with ‘skip’ and ‘read back’ features
5 programmable operation modes (please refer to the table below)
180,000 RPM theoretical speed limit for 2 pole motor
Lost signal protection
