    Wow! My 450 was flying good until I tried to tweak out the gyro a bit.
    I was flying and landed to set the radio so I could adjust the gyro settings. The FM was set to Norm and the throttle was set low and I'm still rotating. As I was setting it the heli just shut down. I was wonder why she shut down. I did not shut down the throttle.

    Now as I spool up to full throttle at center stick FM1 I begin to hear a whizzing sound from the tail rotor. After center stick she looses rotor speed and the tail begins to spin out of control.

    Did I some how mess up the governor setting?

    It's early for me so may be over looking something here, but I'm not understanding fully what the heli is doing. You say you hear a whizzing sound then after center stick it loses rotor speed and the tail spins out of control? Sounds like blade reversal to me. But if all you did was make a change to the Tx, reverse those changes.

    Yeah all I did was land, lower the throttle, but I was still rotating slowly. Then as I was setting the gyro the ESC shut down the throttle all by it's self. I thought; what the heck why did it shut down.
    After that, the problem began.
    The blades are rotating in the right direction.
    I also set the gyro back a few points where it was but no go...

    Might recalibrate the ESC and setup the gov store again.

    Ah ha! Exactly what I was thinking. I just wanted a second opinion.

    If it turns out to be the case; what do you think caused it? Besides me...……….

    Ok guys I found the problem!
    After resetting the throttle calibration and the Heli-Store-Gov, the problem was still there.
    I tried to take off and the tail rotor again seems to be slowing down again. A tail spin close behind. Now I figure I'm back to a mechanical problem. I see the tail rotor stopped and the mains spinning while I check her out.

    At first I though I may have a bad one way bearing when I checked it. Turns out, everything from there to the tail rotor drive shaft turned out to be ok except the 3mm set screw in the tail rotor hub!! Bingo!!! Boy do I feel like a heal! I thought I checked it! But nooooo, it slipped by; DOH!!

    I tired to send a short video but no go...

    Videos you have to upload to youtube then post the link here.

    I'm sure there isn't a single one of us that haven't had that happen. It's quite easy to overlook that little guy. Glad you found it.

    Those tail blades are on backwards. When looking at the tail like we were in the video, it should turn counter clockwise. This action picks the tail up rather than pulling the tail down. Flip the tail blades around, and change the belt and it will fly better than ever.

    lol, I assure you, 99% of people that have built a helicopter have put that tail on backwards. They all think it doesn't matter, and in most cases it doesn't. But if you start thinking about it, it makes perfect sense. First, the centrifugal force of turning CCW will pick up the tail rather than trying to drop it. And second, you want the tail rotor rotating opposite to the main rotor. So if you twist the tail up to the top of the boom, it should spin opposite the main blades when you spin them. This has very little effect on the helicopter, but is one easy way to test if you have it correctly installed.
