Hello friends. I have a big problem. I thought I had burned the main engine. I purchased two new engines. I have changed but still not working. I've tried different batteries (I have 5) and does not work. Just move the queuing engine. The servos are working properly, makes all movements. What I can do? thank you!

Take off the PCB so you can see the bottom. Look for burned traces like this:

if I get the chance to try it I'll keep that in mind. It'll be a while until I can get more "stuff".

No work well the battery cables. I'll buy another PCB. I have seen that there are two types of PCB. The two well synchronized with the remote? thanks

Sorry, I do not understand "no work well the battery cables". What do you mean?

While the current fails. when I give the throttle, just move the rear engine, two seconds and stops working and the LED flashes the helicopter. The servos work and make all the moves.

I understand. That is the "old style" PCB you show from Banggood. I do not think it will work with your new controler. Someone else here would know more about new vs. old.

I had a problem with exactly the same symptoms, in fact it was the tail motor wich had a short circuit. (It happened during flight, ouchh).
And each time I pulled up throttle the PCB went in kind of "security mode" with flashing led.
Try to disconnect the tail motor connector from the PCB (the one with a white and a blue wire) and look what happens.
Maybe it could also be the main motor wich has a short-circuit ?
Try to disconnect the main motor connector to see.

Ah fun.... I was out today at -9C and couldn't get the tail to hold. I had to throw the stick hard to the right to maintain a straight heading. Managed to land safely. I just checked it out in the house and it seems ok. Either the tail motor is flaking out (I'm probably 25-30 flights in on this one) or the gyro said "nope, too cold".

Ironically I crashed my big quad for the first time today. Fortunately it was into a snow bank. It's drying out now but I think it's going to be just fine.

I don't risk big helis below freezing my cheap Gyro gives me the NFW below 30F don't know what the Align's would do but it's to risky. Most of my flying has been with V911 indoors or with my mini quads -17F last night here. My big quad is waiting on parts I crashed it in the cold KK2 board spazzed out and bent a motor shaft and did in 3 props and broke frame. But the good thing is the KK2 is still ticking. I see some guys have made little heaters to keep board warm, me I will wait for the thaw,

Feala.com shows pictures of both boards so you can see what you are getting before you buy they also show both transmitters.
