Trex 450 se v2 Tail spinning.

tbear125 · 03-21-2012, 07:32 PM

Tried getting my 450 se up in the air today, but can't seem to keep it from spinning to the left. I did notice that it looks like the main shaft has a slight wobble. Was wondering if any one has any ideas as to what could be the problem?

Sounds like you need to reverse the gyro. Not in the Tx but in the gyro.

What gyro is it?

1) rudder channel reversed?
2) gain too low?
3) tail blade backward?

I'm running a gy 401 with a futaba 9650 on the tail.

This is really easy to figure out if it's gyro correction direction or rudder stick direction

To check gyro correction
Power on Tx, Power on heli. With the tail facing you move the tail to the right. The leading edge of the tail blades should point left. If they do not, reverse the gyro

Rudder stick direction:
Power on Tx, Power on Heli. Move the rudder stick to the right (this is known as flying those nose for this reason) The nose should move right, tail left. so when you push the rudder stick on the Tx to the right, the tail should go left. So the leading edge of the tail blades should point left.

Easy.

If you have any problems PM me and I'll try to help.

Also make sure your tail blades are spinning the right direction. Most often it's counter clockwise when looking at the side the tail blades are on. Main blades spin clockwise, tail blades CCW. The tail blades should move up into the down wash of the main rotors.

Darn it, I fixed it. I apologize. I was at work and kinda busy when I did that. Thank you for catching it. I feel so dumb.
