The only torque tubes I've had any experience with were align (and various knock offs )
Just joking with ya, but the Synergy gears are extremely robust I have had countless crashes and tail strikes with no consequence.

Nothing is perfect though

when operating around people then the priority is safety management & not trying to save the failed 3D trick,
always must be ready for the correct response when flying heli r/c or f/s, if not able to then should not do smack around spectators,
autorotation is the right choice [power torque off]

Here's a solution for tail failures that may or may not exist.
Flybarless with bail out and headless mode.

Bailout can level a Heli even if it's pirouetting.
So if the flybarless had a bank or channel reserved for tail failure that incorporate a headless mode (it's a feature on some drones that allows you to control tilt and travel related to the external environment and not the aircraft orientation), you could flip that switch it would level the Heli and then interpret cyclic commands "stirring" them for you to allow you to navigate the Heli to a safe location for landing.

Drones calibrate the headless mode via satellite or radio signal. This would be useful with the Heli but not necessary.

It would only need to "lock" the headless input. So after the failure and you have a level pirouetting Heli you give it a small elevator command and you will know the headless orientation. Allowing you to bring the Heli to a safe place to land.

Most flybarless could do this with a software update.

how about cutting the power when heli hits anything

If I'm not mistaken, isn't that exactly what this pilot did?

not right away when ground contact but after trying to correct (save face) the failed maneuver

Forgive me because I was not In attendance, but the whole incident from tail touch to crash took exactly how long?

If you could react faster that he did maybe you need to give classes...

Couple seconds tops.
I think he reacted in a reasonable amount of time.

I have my opinions on the reaction itself,
But I'll keep them off of here because I am not this caliber of pilot. And my only experience with this sort of failure is in simulation.

My purpose for this thread,
Was to find a safety solution,
Not to tear down the pilot.

And? I believe that's what the pilot did... Do you have OTHER information?

I think revmix is saying that the pilots delay in reaction indicated concern for the model over safety.

Nets seem to be the most popular solution.

A center stage net at the least.

"I think revmix is saying that the pilots delay in reaction indicated concern for the model over safety."

Or it could simply have been a split second brain fart on the part of the pilot.

I have mixed feeling on this whole issue. I was at an event 2 years ago where a well know top pilot smashed 4 or 5 machines right at show center over a period of a couple hours. Each time he crashed we were listening to parts/ shrapnel hit the small shelter we were in. His flying was great when he was not crashing, but it does make you wonder at what point is crashing just flying beyond your ability.

delay in reaction
exactly the case; the guy had reflex to lean to the left but not flipping TH at the moment heli hit the ground, safe operation (instant power off) issue near the crowd,
at any maneuver going wrong the operator must have TH muscle memory, practice crash that is
rather a small mishap at ground level than a big one above spectators

I think the guy on the left was the pilot, not the guy who freaked.

then even worse, imminent danger to the spotter because the lack of TH at impact by the operator

Name one top pilot that even uses the bail out feature! Why not just program the damn thing to fly itself? A switch for TH, a switch for Bailout and a switch for tail failures! It's like learning which switch to hit for which emergency! If you don't like the risks then stop going to the shows!

Thanks

I thought the pilot did a hell of a job stopping that helicopter...I was within 10 feet and nearly straight behind the guy who basically caught the helicopter in his lap. From what I could see the head speed of the blades were drastically reduced from the pilots quick reaction hitting throttle hold. The reason he did not engage quicker was most likely because he did not realize the tail was damaged immediately. It was not evident to me or anyone around me that the tail was damaged until it went out of control. Anyone using harsh words towards this pilot should think long and hard about that. Also, anyone thinking that this pilot is not devastated by these events is wrong. It was evident then and I'm sure now that he is more than remorseful and concerned about what happened.

Can we do more about safety, absolutely. I'm sure there will be more review of the incident and thoughtful responses and appropriate actions taken.

if the 3D operator can't realize that the heli hitting the ground & possible damage within a few feet in front of him then not in control operating properly & letting the heli fly away 30-40 feet
