Hi LEBEAU70,

Welcome to this forum, the problem you could be having is motor reversal this happens when an electric motor is what we call flashed and the poles are reversed.

I could be very wrong with this but there is in my understanding no other explanation.

If somebody else can help then please do.

You could try returning it. Or, if you have money, you can trying reversing the wires on the mother board to the motor. Or you can try redoing the wiring in the remote.

Or, if it's flying ok other than the throttle being reversed, maybe just get used to flying it that way for awhile, and it may mysteriously switch back to normal, all on it's own! Smile Good Luck!

Simpler, I'd think would be flipping the tail rotor, but I could be wrong...

 

If I am, there's one screw in the black plastic peice holding the main motors and gears to turn the main rotors that holds the tailboom. You can remove or reverse the dorsal fin thing and cut ahole w. a file or something for the stabilizing bar holder, and it's good.

 

Basically, watch the videos on putting the speed rotor on, and do it up to replacing the rotor.

I don't know if this helps but I replaced the tail rotor blade and had this same problem forward and backwards got reversed! I switch back to the other rotor blade and it corrected it self!

Turned out the pitch on the new rotor blade was slightly different but that shouldn't of switched the controls lol

swapping out tail props is the culprit there. The pitch of the props has no bearing, however the DIRECTION of the pitch has everything to do with your issue. In a close inspection of both props, you will notice that they have opposite angles of attack. There are several way of correcting this-- one is flipping the tail motor and another is switching the wires to the motor. Personally I am not fond of flipping the motor over as that makes the heli more prone to tail rotor strikes on takeoff and landing.

It's a tradeoff. Flipping makes it hit more, but reduces turbulance, I think gives it a little boost, and makes it look stupid while making it more likely to flip and hit on moving landing/takeoff.
