Grrrr. I was down for a week, waiting for a belt. Went out to test this morning, and the tail was responding backwards and was way out of trim. It was just spinning on the driveway.

Would twisting the new belt in the opposite direction from the old one cause this?

Oh, and since we all like to hear of the stupid things we do...

The tail was behaving backwards, so I figure, why not reverse the rudder channel on the Tx? So I go into the reversing menu, with the heli still powered up, and in haste reversed the THROTTLE channel! She spooled all the way up, thottle hold didn't work, then I realized my mistake and put the channel back the way it was. Fortunately it didn't leave the ground, but it did break the little plastic control arm for the tail slider. OK, I say, I have a spare tail slider, but when I looked at it I realize it doesn't include the small plastic control arm So much for flying this weekend.

Oh, back to the question, does it matter which way the belt is twisted? I'm too angry at myself to figure it out

It sure does...........

This is what I do...........

1.) Make sure the tail blades are rotating in the correct direction. With the head of the heli spinning clockwise as you look at it from the top, the forward most tail blade (leading edge) should be turning up into the main rotor.

2.) Set the heli on a table in front of you with the nose to your left. Look at the tail blades........when you input left rudder, the blades should pitch so the "tail" of the heli will go away from you..........if not reverse the rudder channel in the radio.

Once you have set both of those you need to set the direction of the gyro.

3.) When you take ahold of the tail of the heli (still sitting in front of you as above) and move it quickly toward yourself, the tail blade pitch holder should move away from you, the blades trying to move the tail away from you. If this needs to be reversed it will be done on the gyro, NOT the radio.

If you do all 3 correctly then you can safetly lift the bird off the ground with the tail going in the correct direction.

BTW...............there are excellent videos explaining all of this on the "other" forum......

If this doesn't make sense, ask me and I will try and clarify things

I need help identifying the correct part to order. The part that broke is at the end of the rudder pushrod, at the tail. The plastic containing the ball split in half.

Does the image above look like the right part for the 450SE? It is at this link http://www.grandrc.com/inc/sdetail/30750

I also found this one, but it does not have an image: http://www.grandrc.com/inc/sdetail/43525

I already have a spare rotor control (the metal part), and just need the little black control arm that has the ball on one end, and the screw on the other.

Thanks.

Thanks Lenny. I'm sure that will help other people as well.

I have watched those videos, very helpful. All I did here was slap in a new belt, and didn't realize I might twist it the other way.

Always learning, but it is frustrating all the same.

On my next heli, I am ordering a second for spares. That way I will have one of everything.
