ESC had worked flawlessly after build checks, and pre flight.

On the maiden of a new glider, the motor cut after 2 mn (second climb).

After some testing, found that a brand new ESC 50 A from HK had the thin wires that go to the receiver, with stray wires near the solder on the board, which depending on the position of the wire made a short. So before mounting a new ESC I will now check how these wires are soldered to the board.

Had the luck to be able to land the plane safely without damage.

Cheers.

Which brand is it?
Turnigy plush are usually pretty good but I would not install Hobby King branded ESC on anything I flew.
I had a lot of failures with them and I use a very cheap 40amp esc covered with pink heat shrink from ebay. Having said that I don`t know if they are still cheap as i haven`t bought any for a while.
The only problem is that they don`t have automatic cut out as they are simonK quad ESC`s.
Wot, no Depron?

Most of my esc's are HK ones and really other then a couple 35A ones no issues. The 35A ones would cut out for about 30 seconds (motor only) and then start working again. One is attached to my servo tester permantly now.

It was a H-King 50, I have flown my Phoenix 1600 last summer with one without any problem (many flights).

The defective one was really a botched job, all three wires have stray wires, I was very lucky because during my tests back at home, I noticed that throttle had an action on the servos, the first thing strange I noticed before the motor not starting, was that my glider didn't want to fly straight ( it is not my first glider, I did check that my controls were well centred before flight).

Everybody gets a bad one now and again.

I never had an issue with any of the HK ESC's I've used. Most are of the 60amp variety.

Also use SkyWalker and Turnigy Plush so far no problems with any of them.

EDIT:
With one exception. I don't trust anybodies soldering but my own. I always re-solder the bullet connectors if the ESC came with them by default.
And on the 8th day God said: "Go NAVY",.. and it was good! Pray like everything depends on God. Prepare like everything depends on you.
