Well another miss hap in the flight of electrics...  This time it was my Phoenix 45 after replacing a NEW AXI 2826/10 New replacement from last flight mishap, after 2 laps in flight my ESC went up in smoke, landed and pulled plug it was toast.after checking AXI motor for any problems it look and check out ok, installed another ESC wit no problems Hummmm !well I guess I will try to have it repaired.  Might be an ICE on order nextime.....

I have had an ESC go up in smoke on a subsequent flight following a crash. I wonder if some of the FETs blew before the auto shutdown occurred at the time of the crash?? It was a cheap ESC so I just attributed it to having come to the end of its life or being overrated as to its capacity. Humm!!

Guys,

This brings up a good point for discussion. After a crash or even a prop hit (nose over) that causes the motor to stop what can we check to insure we don't lose the whole ship in the middle of a wingover on the next few flights? I have had a couple situations that have cause the motor to be stopped and always thought the high current protection would shut down the system before damage occurred. I have always used the factory setting on high current but is this enough or should be set it lower?

So far the system protection has worked for me but without a way of checking what could have been fried even slightly we are exposed to a serious weakness in the system.

Only other thing that might be worth looking into is a fuse link.

Dennis,

I am not sure if a fuse is really fast enough to keep the ESC from damaging itself---but I don't know for sure. At least in CL, if the fuse blows, you still have control (unlike in RC where you would lose receiver power too. I assume the fuse is on the battery. Of course you would need a 45-50A fuse, depending on the ESC you are using.

Rather than a fuse, I think simply running the system through a run cycle on the ground should turn up any stresses. Of course the main issue is whether you should leave the original prop on---which in my case tends to load it statically as much as I see in the heavy maneuvers during actual flying. Maybe just do a one minute run with the flying prop is enough to see if anything will "pop". If the system is weak, maybe that would do it.
