I have a Blade 450 3D. I fly with a Futaba 10c Transmitter I had everything setup, everything working correctly, gyro sense, heading hold, and the right amount of throttle and pitch curves. The heli was flying great.

Recently I was going to lift off in somewhat of a gravel area ground, and once my heli spooled up and the tail rotor engaged for heading hold/gyro...a rock shot up into the tail rotor, causing the tail rotor blades to break and the tail slider. Also my main rotor blades were chipped from previous flights.

So I have replace the tail blades, and the slider, and also replaced new - balanced main blades. ---- My issue that I'm having now is:

1. When bringing my heli to Idle, the tail starts spinning around with no control input, as if the gyro is not engaged.

2. I seem to have no lift at full throttle.


I have not changed any of my settings in the transmitter before or after the repair.

Can anyone please help me resolve my issue, whether they know, maybe my gryo is broken or a servo?

Thank you

You've probably found the problem by now. If not, check the belt and gog gears driving the belt. Likely stripped the plastic cog gears. If so change to the metal tail drive cogs.

Hi cptkirk,

Thanks for the advice! I'll remeber that in the future. I did fix the problem. It was a simple error on my part. It ended up being the tail slider. I replaced this piece, however I installed it reversed , causing the tail to spin out of control.

Thanks again!,

Another mistake ive made with the b450 is the tail blade grip links to the tail slider can easily get reversed during a rebuild.

Make sure the control ball coming off the link is facing towads the front of the heli when near the top
