OK, I'm out just hovering my Raven and when I give full collective the tail moves to the right. I land, figure my Gyro is going so that I can increase the gain and take off again. Get about 20 feet up or so and the Heli starts Spinning, NO TAIL ROTOR Control at all. I go in hard enough to break the head, landing gear etc. Figure that the Gyro conked out. But, I find out that when I rotate the main gear, no rotation on the tail gear. I don't have it apart yet but "something" screwed up in the tail which caused the tail rotor to stop all together.

Sorry to hear about the crash.

It seems the heli was talking to you... probably one of the set screws on the tail system got loose.

Next time hit hold to soften the crash or even auto down. The heli would have stopped spinning...

It's easy to find an excuse to do wrong. Hard is not to find an excuse to do right.

BC Don...
ever thought of taking up golf? It's got to be cheaper than all the crashes you've had lately!!! Man I feel fortunate! Sorry about crashing again though...

Later...

PZ, don't have enough time for golf but you are correct, it would be cheaper. In any case, I figure I'll keep at it. Got my TRex together and had an initial flight today - no crash with it but I do need to change the pinion gear to get the motor heat down.

Yup, hitting the hold may have helped a bit but shouldn't cost too much to fix. Didn't appear to be too much damage overall. I'll be checking more later.

Bc Don,

You need a vacation here in Vancouver. We will sure get you going...

Hey Don,

Sounds like the set screw pinion on the tail may have backed out. I have seen that before. Causes you to stop driving the torque tube and the tail rotor pretty much packs it in ;-).

Let us know when you go out again, we can meet and take a once over to see if something is missed.

Trevor.

JackHeli, lets see, cold & sun here or warm & wet there during the winter. Naw, think I'll at least have the sun even if it is cold.

Trevor, thanks for you assistance. Once I've got stuff together again I'll PM you and see if we can set up a time. Days are getting a bit shorter now though.

Yup, just dialing in the TRex now. Should be all ready in a few more flights.
