Hi.

Im suddenly experiencing my mcpx to cut the connection at about 70% throttle.
Ive tried brand new batteries, but no luck.

Is there anyone out there that might know why this is happening ?

How old is the motor? Brushed or brushless?

Its about 2 years old, mcpx v2 standard brushed motor.

Do i need to replace the engine?

Check the battery wires on the 3-n-1 at the board and at the battery plug. There have been problems in the past with the wire fraying and only a few strands making the connection at the solder joint. Peel off the white silicone encapsulating the wires at the board and remove the shrink tubing at the plug to inspect. The cause may just be wear and tear from plugging and unplugging the battery, shoddy soldering by the factory or a combination of both..

I can see your original post, and the one you wrote about the age of the motor.
Did you write more??

Hi.

I wrote that the wiring is OK. I resoldered the wiring from the 3n1 to battery connector just to make sure that wasnt the problem.

Should I consider buying a new motor, or mainboard?

Maybe it's the throttle curve on the transmitter.
