Its was running fine for years but not yesterday after it halted and took it home for check up. I'm runing on duratrax vendetta 1/18 truggy. Have never gone over heat because the gear and speed are very much stock and warm.

At home i dismantle and tested each parts of the electronics to a substitue rc models of exact same spec and electronic component to narrow down the problem. Yes it was MAMBA 25 ESC was the problem. I tear open the protective layer of plastic shrink wrap cover so i can check the circuits for any fault and short circuit.

Test:
--------------
1. ESC + LIPO = functional, the light blinking, no overheat

2. ESC connect to USB for computer tuning = alive, i can still do some tuning in windows.

3. ESC + LIPO + MOTOR = functional, the light blinking, no overheat

4. ESC + LIPO + MOTOR + RX =IN 1 SPLIT SECOND IT HEATED LIKE BOILING KETTLE AND ALMOST BURNED MY HAND WHEN I TOUCH THE FET CHIP!:eek:

*Even when i had my M11 Tx on and off. Still remain the same.:eek:
My RX module SANWA M11 2.4Ghz run ok with my other spare sets of MAMBA 25 and Sidewinder ESC. It seems the esc have problem connecting to rx.
I wonder if anyone had similar problem like this?:confused:
Thanks.

Below are my spec:
---------------------------
-MAMBA 25 brushless esc
-Turnigy 2700kv 370 size brushless motor
-49T spur/ 14T pinion (excellent loose binding)
-Sanwa 2.4Ghz rx
-Rhino 25c 1800mah 2s lipo
-Hitec HS225MG servo.

I've not read about any known glitches with any 2.4ghz rcvrs.

I'd give Castle a call and see what they can tell you. You mighthave a prob with the esc. I run 6 Mamba 25s and none have probs like this.
