hi all my tr250 esc that came with my combo kit in dec 2009 seems to have failed.last week i took off and it got to around 4ft had some kina fart then lost power.the esc chirps the motor on start up as normal.the motor slightly moves when the thr is moves up but thats it.tryed to rebind and its the same as above.has this 4 year old esc now died

Heli Yea! · 08-18-2014, 03:30 PM

Maybe so, but first redo the esc programming it may be throttle range is out of wack. first in your TX change all throttle curves back to linear then reprogram it. make sure timing seting is mid and brake is off.

Heli Yea! · 08-18-2014, 04:53 PM

Do you have the manual? if not I can post a guide just say the word.

dayshaddow · 08-19-2014, 09:38 AM

hello heli yea i still have the origion manual so will follow your advice.i think you may be onto something with thr range.there is no sighn of a burn up,the esc can pulse the motor so if it can do that then its gotta be still working

if it isnt im not to sad 4 years and i dread to think how far its actually flown

suppose in good testament its a good cheap heli,and takes lots of bashing

jperkosk · 08-19-2014, 01:42 PM

Good call, Chad. The ESC will not arm after the power-up if it sees anything over 0 signal from throttle, so the throttle range calibration is very likely to fix the problem.

sutty · 08-19-2014, 02:20 PM

Not saying it won't work, but I have my doubts. First, it was flying when it bombed out, so if the range was incorrect, he couldn't have armed it for the flight. Second, if it was calibrated before, why would it have changed. Third, it makes all the tones, and then tries to turn, after the correct tones, which means it is armed, or it would be completely dead.

My guess is that the connections to the motor are down to two, which makes them twitch, or turn very weakly, and the ones that remain is one of the ones for the motor beeps.

Could be the motor, or the ESC, or just the soldering or the wiring between the two on one of the three phases.

Would be very easy to check if you had a different motor, with a bit of botched temporary wiring, I suppose.

Cheers

Sutty

Heli Yea! · 08-19-2014, 02:42 PM

That makes sense. You can take the blades off and jiggle wires on the bench. When it cuts do you hear the ESC reset and start the beeping over? if so battery connection is loose to the ESC check it over.

sutty · 08-19-2014, 03:47 PM

It won't be on the DC battery side, as the esc is powering up. I'd put a bit of money on it being one of the three phases to the motor being down. Wiring from the ESC, or to the motor, the bullets inbetween, or even the motor coil itself.

Cheers

just started work on her a found a broken wire(blue) from the motor connector,quick soldiering and fingers crossed

wish me luck peeps

Why wasn't I surprised?

Sure rub it in Andy. I'll pay pal you a quarter to call someone who's willing to listen to your sucker bets.

sutty · 08-21-2014, 01:30 PM

Yeah, when I said a 'bit of money', about a quarter was all I had in mind.
