Default Phoenix 80 FIRE

I've just finished putting (back) together a Hangar 9 Spitfire, with a new Hacker 50-12L, a Phoenix-80 ESC and an Uber BEC. Ran the servos before mounting the
motor and everythins seemed fine. Put the Hacher in, powerd up and a second or 2 after the OK beeps, the Phoenix burst into flames.
The Throttle stick was still in the zero position and nothing else was touched. I'm stuck wondering if the ESC (brand new) was simlply bad somehow, or if there
was a short of somekind in the motor.. The battery was warm (not hot) from the, maybe, 3 seconds it was connected.
Does anyone have any ideas what could cause this?

Most likely the battery was connected backwards. I've seen this several times.

Definetly not the battery (deans), as I mentioned everything was tested (hot), and worked, before the motor was connected. If the battery, or any connectors were reversed
there would have been an immediate short.
Anyone else have a clue?

For anyone interested, the problem was the Castle Creations Phoenix 80 ESC [:'(]
I put in a CC Phoenix 85HV with no other changes and all is good> Can't wait to get this bird back in the air!!

Out of curiosity, what was your cell count on the battery? I only mention it because you are now using the "HV" ESC, and the thought came to mind that perhaps the CC80 couldn't handle the voltage.

That was my thought too. The 80 will only handle up to a 4S pack.

The CC PHoenix 80 (without the BEC) is rated up to 25.2 Volts and a 6s Pack.

It was also the recommended setup for conversion of the Spit to electric. (horizon Hobby's recomendation. Note that mine was done before HH came up with the electric
conversion recomendation. I got the plane from NE Sailplanes - http://www.nesail.com/categories.php?subcatID=115

Ya, i have to agree. My friend at our local field has an LR-1 that he flies. It originally had a CC 60HV with 6cells and a 10x10 prop. Made it about 180 flat and level. He had an axi motor that he ran more than double the recommended power to and eventually smoked the esc. Now he runs 9cells on a 110 or 120hv. He resantly ran at the houston DOD flyin and hit 243mph. Moral it, if your gana run lots of battery, check the specs. You may have to cut the red wire Bye bye BEC....

Of course the BEC was disabled. Having said that, the fire was almost immediate (no servos operated & motor not engaged) This was
simply a defective ESC, and it's the second one (80) from CC -- End of story.

Drop in at the PCC field (just south of half moon bay) and see the spitfire in the air! http://www.flypcc.org

WAK,

Sounds like it was setup right. Too bad about your plane! I had a Castle 80 smoke on my bench. Sent it back for a new 85 HV. I haven't had any problems with the 85 HV esc's. Is it always windy out there I have been by there many times, but never flown. How's the fog in the summer?
