HBCP2 - Tail motor

[Maradona]

Hello guys !!!!

I´ve got a HBCP2 and I been having problems with the tail engine.
I´m already changed two (always original parts).
The problem is that it causes overheat of the RX.

Yesterday I changed the new one and when I connect the battery it starts working crazy (Obviously, my throttle is at cero and the idle is ok).

Do you think that this problem cames from the RX ?

Do you know any test to do ?


Thank you all.

I would try to reset the 4in1. Some people suggest to move the proportional from one extreme to another and then set it in the middle. After that, switch on the 4in1 while having the TX switched off. Then switch on the TX and wait for the green light to become solid.

Thank you for your suggestions.

I´ve tried it, but nothing. Apart from that I disconnected the two engines and switched on the 4 in 1, but nothing. Its important to say that all of other things (servos, main engine) works well. Something is happening inside the 4 in 1.

Thanks.

I would open up the 4in1 to see if any of the mosfets have burned out.

Finally, I had to change the 4 in 1. It was in short circuit.


Thanks you all.
