Hi
I was flying my Wind 50e today with a Hacker A50-16s and while throttling up for an up-line the motor made a horrible noise like gears stripping.
I filled out the repair request from Aero-models and will send it in tomorrow, but was wondering if anyone had an idea of what happened.

Thanks
Randy

Magnet came loose maybe? What did it do on the ground? Are you running any ESC braking? I've heard of some issues like that if the braking is set too high.

I've heard of the magnet theory, possible.
On the ground the prop rotated back and forth only about 20 degrees.
I haven't taken it off the plane yet to see if I could see anything obvious, tomorrows project.
Oh, using 25% brake.

probably a magnet came loose

Woodie

Is that fixable by me, would that void any warantee if I take it apart ?
I'm assuming that if a magnet came loose at high rpm, there might be more damage.

I would send it back to Hacker. They have the right tools, glues, etc, to repair your motor. Or replace it if damaged too much.

Woodie

hi Doug,
just logged on for info on just the same problem. i have a Hacker A40-10S and an airboss-80, i have found that the amps are spiking very quickely and the speed controller is kicking out from too many amps, it makes a terriable noise when this happens. Once i hooked up the watt/amp meter it was easy to see and i thought dialing back the throttle travel to keep the amps under control was the way to go but that means dialing the travel back to 37%, i think this is strange but was told to go ahead and run it for now. So, four flights later i have nothing at all working i have two ESCs and changed over and i still get nothing. Ido see the bind light blink on the rec. when flipping the switch. i have emailed the hobbyshop and have not heard back from them

sorry here, desertrider49

No problem

desertrider49,
do you think you are having the same problem?

I don't think so, my motor had about 480 5 to 6 minute flights. I didn't see anything before I sent it in for repair. One thing I did notice, one of the connectors between the motor and controller seemed like the solder joint could have broken loose, I haven't looked at it closely yet. My noise only happened once and the motor stopped working.

oh , got to be a different problem then, the hobbyshop did want to know if i might have a "cold solder joint" somewhere so i reheated all five joints, it did not help me but that might help you with your trouble.

this setup is brand new. 4 or 5 short flights. motors been kickin out from the start.

if i understand it right, a bad solder joint will cause high resistance and that causing high enough amps enough to trip the breaker in the esc.

My guess would be timing problem.

Talked to repair this morning and the motor is fine, it's the soldier joint on one of the connectors. I plead ignorance since this is my first electric plane. haha

Randy,
it's your esc. Get a better one. I had an A40 and an 80amp airboss would not work.

I dont think anytthing is wrong with either component.
Sometimes you run into motor/esc combos that just dont like to work together.
Try another esc and I bet you wont have an issue.
And always check your solder connections

Thanks Guys,

But check the date on the posts, this forum is 8 months old and the problem has been solved (see my last post #16, bad connection).

I wish a thread could be deleted......

Ooooooppppppssss!!!!!!

sounds like the brake

Sorry for taking so long to get back. But I must tell that my problem was not the motor at all. It is the ESC. Because I had an 80amp ESC with a 40amp motor I never suspected the ESC couldn't run the motor and the reciever properly. The Hacker people sent me a CC 75 Ice and it's been running perfectly ever since.
