Transmitter/ESC/Motor issues

Questions & Help

Hi guys, just reposting this as separate as I haven’t found a solution to this weird problem yet:

Here’s a link to a couple of test videos: https://drive.google.com/file/d/1CB-_pG__UBO_RJ41EyNbDnK7AVm69zfy/view?usp=sharing

and showing the throttle: https://drive.google.com/file/d/1DRGNKPxEf_X9hHaqEyQooBkAwu56cTn3/view?usp=drive_link

I hope you can see in the second, but as I push the throttle up on my remote, the brushless motor kind of cuts out and then slows down back to the minimum speed.

When I go full throttle, all the way to the top, the same thing happens, and the same happens without the blade attached to the motor

Is this an ESC, motor or transmitter problem, and how do I go about fixing it? Unfortunately, I don’t have any replacement motors/ESCs to test against. If this is an ESC / motor problem, then please bear in mind these components are about 2-3 years old, and were just sitting in a cupboard.

Cheers guys,
Ollie

P.S how the heck do I sign up for Infosec? I can’t find a link for a google form anywhere lol

I’m thinking battery to be fair. Whenever I’ve had that throttle loss on a spinner it’s normally been because I’ve been flying too close to the sun with regards to discharge rates and current draw. It’s an abnormally large load for the motor.

Have you got a bigger pack that you could test that theory on?

Otherwise it’s going to be the ESC trying to save itself from a current draw or spike. If it’s a bheli or similar programmable one you should be able to link it up to a laptop and turn off the boring safety features that stop it from having too much fun.

Do you have a smoothing cap on the ESC? Could be a little spike that is causing a mini brown out which then needs the throttle reset before it goes.

Likely a battery issue. Had this a couple of times with previous large horizontals & switching to a higher C rating has helped significantly with the brownout problems previously had.
