The jst battery plugs overheat and the low voltage cuts in. Cools almost instatenous allowing rebind. This is a common problem with jst plugs

Two options, dismantle and solder the wires to the crimps, or cut off and fit a better plug

Hobbyking has a really nice tee plug, like a scaled down deans, perfect for these size heli's

How about posting a video of what it's doing. If the motor is turning, but the blades aren't, it won't take off.

Hi mdon

I had the same problem with the FX071c and it was the power switch was defective. In all my FX071c, I removed the power switch ..... I had two cut off like yours ....

See section #11 photos 41 and 41a for bypass this power switch.

And kiwi_craig solution is good too....T connector male female

When the red JST connector becomes hot, red becomes darker due to heat generated in this connector.

The JST connectors for power is not a perfect choice. The choice for the connector in FX067c is better....

Does It contrasts well with the V913 with brushless drive motor?
Although the tail walkera looks good and fine, after the sad experience with the 22E (2.4 gh) and another for hardware, software and prices, i don't trust more in this company;
This company will have 'certainly reached levels more' high, i wish it great success!! At the same time I continue with the use of motor h.bee to see the border line.
I can't compare the FX052 tail motor to a BL motor since I haven't tried one. The motors I am using haven't needed changing so no need to swap out.

I have swapped out the main drive motor for a BL one and highly recommend it.

ESky Honey Bee Super 370 motor

I know some people here have tried it and liked the results.

I have one I plan to try, and I am curious as to what pinion gear seemed to work best for others.

Anyone?

I found it no better than the stocker, they really need 3S voltage. try the same size to maybe plus one more tooth. Don't expect any miracles............

A likely better brushed motor is the Walkera "400" as fitted in the master CP and 400GPS

I melted a board with 3S - not doing that again.

I have 8T, 9T and 10T pinions - I think I'll go with a 10T.

I'm not after a speed demon - stock performance is fine for me on this bird. I want to keep my camera and other attachments for it, I don't want to cram a bunch of electronics under the canopy by going brushless, and I want better motor longevity with being able to repair the motor instead of replacing it when the brushes are done. So if the Esky motor compares roughly equal to stock, I'm in. I have this bird for easy relaxing flight. (Also, everything I've found on the Walkera motor shows it to be internally brushed - and so I'm not interested in it.)

When I want excitement, I have a Blade 300 CFX and a Nano CP X for real speed and serious agility.

Sounds like the main gear or motor pinion might have lost a few teeth?
