| Droid, you are a tool - and you are making a fool of yourself, IMHO:
>>Charles are you saying that i'm lying??
>>And for those that didn't get it
LOOSE AND SPINNING
>> Charles are you lacking something upstairs??
>> torque because it was LOOSE AND SLIPPING!!!
Is that plain and simple enough for you to comprehend???
Charles is a VERY experienced pilot and meticulous builder, and after reading everything, I think he's RIGHT! How is it possible for the tail rotor to generate enough force to have the set screws strip the splines on the couplers??? Think about it - it's virtually impossible! The fact that the spines were stripped indicates that you torqued down the set screws correctly. The only thing that makes sense is that the torque tube or TR blades got jammed or locked, and the engine or inertia of the main blades put enough force to do the damage you documented.
Assuming everything else checked out mechanically, what's left? radio /electronic/etc failure. I lost my TR control once when the TR servo plug worked it's way out. This may be a likely scenario for your crash, and if there was enough damage, difficult to reconstruct (why don't you check your gyro wiring if you haven't already tampered with it?).
From your original post:
Model passes at 30 ft bank to its right and on the exit (knife edge)violent tail movement.. tail control gone..damn must be the servo!
Violent tail movement doesn't sound like slippage, does it?! And you said yourself, must be the servo ...
But if you have blinders on, jump to conclusions, and yell and berate people who are trying to help, you won't learn from this crash and it may happen again.
I believe if you step back, chill out, and reconsider, you may change your mind. And then you will have an enormous helping of humble pie to eat. And owe Synergy, JK, TB, and Charles apologies.
BTW, Heliman, I don't believe it's a pure friction joint. A pure friction joint would have a smooth coupler without splines, and use something like a hose clamp around the TT rather than set screws. You may not have designed it this way, but four set screws into a TT into splines on a coupler seems like a very solid joint.
Lastly, Stu. - most of the issues you listed are manufacturing/supplier issues. Yes, QC could be better, but I believe it will improve. This is their first company/heli. Give them a litlle slack!
