I have an issue, My mini vbar is acting weird and I hope I can get some help. I set it up with the typical mini vbar setup, I've set the tail up correct but when I spool up the helicopter spins around on the floor. So I thought I had the gyro backwards, connected it back to the computer and I switched the direction. Spooled up and the same thing happened, I set the gyro gain and couple of points higher thinking that was it and it just pirouette's on the floor. The tail servo is Align BL855H High Voltage Brushless Servo. I'm not sure if I'm doing something wrong or what but any help is appreciated.

Ok first thing I would do is go the the transmitter tab in the Vbar program and make sure my reversing in the grand is correct. Even if you think it is check anyway. Seen that wrong a lot. Then go to the sensor tab and make sure you have the right directions picked. Then check your throw direction on the servo and reverse if necessary to make the throw go the way it should. Check the correction buy moving the tail right and left. If you move it right the trailing edge should move out that way also. Whichever way you move it the trailing edge of the tail blades will move that way also. I think that is a tail belt Heli I would make sure the belt twist is right and the blades are on the right direction. Usually tho what happens is ppl will change the servo direction in the radio instead of the software and that messes everything up. That is what I would look at first. Once your transmitter is set according to the Vbar software program don't change it

Either the tx is calibrated wrong, the wrong picture for the gyro is selected, or the tail is reversed in the tail setup tab. If all of those things are correct, then you have a bad servo or a linkage binding badly...

I checked everything,the servo goes in the right direction and it still spins around like crazy. I think the vbar is bad. I'll put a beastx on it to see.

How do you know the servo is going the right direction? Also did you check the calibration of the transmitter? Did you check to see if the gyro was correcting in the right direction?

His heli orientation setup wrong ? Tail direction wrong. Belt might turn wrong direction, tail blade in wrong position, tail stick wrong?. And when u hold the tail drag to the right hub should move to the left opposite direction. Same thing to stick rudder on your radio.
