Great ESC. Used in TT X50e. Programming card a must and for £5. A little bulky compared to other amkes making mounting a litle more difficult. Seperate progeamming lead a good idea. Running 6S and 1100kV>YEP 20A SBEC>UltraGuard.

I have had many cheap Hobbyking items and I've never had a problem. This has been the first problematic electronic thing I've had from Hobbyking in the thousands of pounds I have spent here. This ESC was pretty cheap for what it does so I went for it (bear in mind that a YGE is completely and utterly overpriced, even if they used military grade components then you could not make it cost that much). It worked 100pcnt perfectly for the first two flights in my helicopter (a Hirobo Cobra). Then on the second flight the motor started cogging on spool up... So I put it on the bench and made a voltage booster for the throttle signal. This made it work better but it had lost all of the settings. Re-programming it made no difference. I kept trying and eventually it totally died, it won't even power up now. I took it apart to have a look (I am an electronics engineer by trade) and nothing seemed amiss however the main MCU (ATMEGA168) had totally died. It's very unusual for an Atmel chip to die like this so clearly they are using QC rejected items. Very unimpressed. Now that I've opened it I cannot get my money back either...

Bulletproof ESC, will put this in my Dechatlon 2450mm, with 6374-200Kv motor. Same as YEP 120A HV, but cheaper :)

Upgraded my trex 600 to a 750mx motor so needed an upgraded esc, so purchased this. 3 flights today and very thing running great. I would recommend as it is alot cheaper than the castle equivalent.
