Help!
Ticking !!!

Has anyone experienced this. I was flying my slowstick with BL motor 2410-12. Had a decent flight for 15 mins and landed well. Wanted to go for a second flight but the motor would not start. It only gave ticking sound (not beep but tick) one per second. I disconnected the battery and ESC and tried everything. But the ticking would not go away.

There is no damage to motor and the coils are ok. The ESC also seems ok. Earlier when I connected the ESC to LiPo, it would give me a single beep saying all okay ... go fly. But that beeo has also gone ?????

Help... I hardly get peaceful days to fly...

When it first started ticking, I would have suspected a bad connection to one of the motor wires or an obstruction in the motor preventing proper rotation. It is very easy for a motor to ingest a bit of magnetic grit that lodges in the small gap between the stator and rotor (happened to me). If the motor can't turn properly, it is possible for damaging currents to flow. That might account for the absence of an arming tone in the ESC later.

Agreed. It's probably a bad connection. Check your connectors between the ESC and motor. They should be very snug.

Bad bearing, magnets striking the stator... from my experience those are the prime suspects when it comes to a "ticking" noise. If fixing the connection doesn't work, pull the motor apart and inspect the stator heads for scrape marks. Even a small bit of shine indicates a problem, which is often fixed by cleaning the magnets with tape and blowing out the stator with compressed air. Also spin the bearings while it's apart. Listen carefully; a "gritty/grinding" sound indicates a bad bearing.

Thanks guys but I have changed the ESC and it works fine now. the same ESC is causing ticking in other motor too so I guess ESC has konked off but then there are no indications of burn, heating, physical damage nothing... strange

Check the servo plug on the ESC, I bet the signal wire came off the ESC.

Finally... proof positive a free energy device exists!

Either that or Parambir is not telling the truth.

There is no reason why I should be lying... or maybe you think because I seem to have done my homework before posting the thread...

Mankind has been searching for free-energy/perpetual-motion for centuries.

If you can really get the motor to continue ticking (or any sound at all) w/o power then get in touch. We will be trillionaires before end of year.
