Aeronavics / Droidworx Help - Maytech ESC smoked on power-up / first throttle application

[Efliernz]

Hi guys.

I'm helping a noob out who has powered up his DW SL lite for the first time tonight... and the smoke escaped from an ESC when the motors first moved (6S pack) (without props). The ESC still runs... Photos below...

For those that have used this (DW supplied) setup and parts, has anyone else has problems with these ESC's (before he orders a replacement 3rd-party esc)?

Cheers

Pete

This things can happen with just about every ESC......most of the time it's something creating a short on the circuit board. Just go ahead and buy a new replacement.....brand of the ESC is less important than most people think:

Pete email Tom at DW and ask his advice. If DW have supplied them they should know about the issue. I am sure he will get a replacement from them. I would also have thought that IF DW supplied the ESC's its what they have found to be the best for there craft.

I'm having that hot esc issue now. Mine are Maytechs. I would have flown it Sunday morning if I had not felt that one esc was almost too hot to touch. I have a spare. (I always order extras of every thing) Tonight I disassembled the 450, took that arm off and left just the esc dangling from the power distribution board. Disconnected that esc from the Naza. Looks like an easy part to replace. Some unsoldering. We'll see what happens.

That esc ran so hot without a load that I think it's a no brainer to try replacing it first. My soldering joints look solid.

I think any brand can have the odd bad one. Droidwx swapped it immediately without a hassle
