Hey guys, first weekend with the Kontronik setup, awesome gear.

My speed controller chirps during flight, can't figure out why, but doesn't seem to affect anything, any ideas?

What do you mean? The sound in electrical sounding? The ESC does not make noise....it can't....not speaker of any kind on board. The ESC tones are heard through the motor but if it is turning, how do you hear a chirp? Are you sure it is not a bad one way or something???

What are you doing when it is chirping? Full collective, pitch pumps, Or just random chirping? Maybe try a reset? Are you on mode 11 or mode 4?

It just chirps ... chirp, chirp, chirp ... definitely electronic sounding ... very consistently, I assumed it was normal ... The Logo 600SE is so quiet it doesn't mask anything, if it was any other heli you probably wouldn't even hear it.

Try reprogramming the esc and see if it goes away. If it doesnt then I would move the motor away the main gear so the pinion does not touch the main gear and try to run the motor and listen for the chirping then. If it doesnt chirp then most likely its something else. If it chirps then something is going on with motor and esc..

Thanks - so you think it may just be gear noise or RF generated by the setup causing the Jive to chirp?

The Jive cannot by itself, nothing in there that can cause sound, so it must be the motor or something in the drivetrain.

Hmm... ok, I'll troubleshoot further, I guess it could be something else, it just sounded so electronic I assumed it was the Jive... Maybe gear or belt...

Thanks, guys!

Edit: The Jive generates the setup tones, it sounds like that, but just one "beep" about every second or so.

It's not the Jive that beeps, it's the motor, so creating those tones when the motor is spinning is as far as I know impossible.

Ahh! Didn't consider that, new to electrics, assumed the speed controller generated the setup tones.

Ok, a bit confused, how does the motor generate the tones? I thought the three leads were the ends of the wire wrap? I've never had one of these apart, so just curious ...

Quoted from another forum;
you simple energize the same pair of coils (so the motor locks in one position) with a pwm frequency that is in the audio bandwidth (say 1kHz...). the duty cycle will control volume.
to generate a tone you will need to switch PWM frequencies (like a telephone dual tone).

For starters as you say new to electrics, could it just be the sound that particular motor makes? What motor and setup are we even talking about here?

I know for example my Pyro 700-52 on my TDR makes abit of a high pitch whine here and there when you load it up, different noise but its normal persay.

...Once upon a time there were Nitros, flybars and frequency pins...

It's a Pyro 700-45 on a new Logo 600SE, and the best way I can describe the sound is an electronic "chirp" every second or so.

Maybe steering this off topic but don't bearings have grease in them? Won't oil just thin out the grease and shorten their life?
