Hobbywing ESC

I bought 2 Hobbywing Skywalker 50A ESC. One works fine and the other burned up after a 30 second flight. Both drawing about 35 A. I figured oh well, thew it away, and bought 2 more. The first one works (so far). The second one has a dead short. When I first plugged it in there was a giant spark and then nothing. I checked and found my Gforce 2200 60C battery now reads 0 volts. I tried another battery by just barely touching the contacts and same thing. Giant spark but it didn't hurt the battery.
Has anyone had issues with these or was I unlucky and just got 2 out of 4 bad ones?

I'd take a look at the Hobby King YEP's

Should you decide on it, here's some buddy codes http://rcsearch.info/hobbyking/buddy/?strSearch=yep Don't forget the programing card-- it comes set-up in heli mode.


For those running higher cell counts, there Hv model has been a big hit with a lot of guys.

Try pulling the heat shrink off and see if you can spot the short. I've had a number of similar problems with another brand (Red Brick) where the alloy heat sink comes in contact with the motor wires. The solder connection from the motor wires short against the metal. Because of this I will take off the heat shrink before powering any ESC that comes held together by heat shrink. I will then glue the sink to the components with JBweld and leave the heat shrink off for better cooling.

Thanks for the idea. I will take a look.

Ok here's how it works.. If you have found an ESc on that link I posted, you need to be logged into Hobby King first . Then all you do is to click on the link on
http://rcsearch.info/hobbyking/buddy/?strSearch=yep and it shows you the reduced price.. Just make sure you know which warehouse its linked to. There's the EU, UK, US, AS if it doesn't list one of those, it's from China..

I save some cash last fall from this site.. Bought 2 --120HV's for about $80.00 ea at that time.

If you can find one from US warehouse, it doesn't take to long to get them.

I pulled the covering off and "looks" perfect. Using an ohm meter it is definitely shorted but can't tell where.

I have ordered and used 4 or 5 of the hobbywing esc's this year and all have worked fine - I have a few of the yep esc's and they have all worked good too. But they could have had a "bad" run. Maybe you could just send back the bad ones.

I have bought 3 HobbyWing Justock for my RC trucks and they work great!!! I must have gotten a couple bad ones for the jets. It happens with any manufacturer.
