well the bench worked for me it was safer then the guy t the hobby shop holding the bird in his hand.

i spooled up with the heli in my hand once and my thumb got burned by the motor i dang near let the helicopter go.

but when in you hand or on a bench you never use full throttle so i dont know what the big deal is if you know what you are doing people have been bench strapping birds for years.
this bench by art tech is very nice
and notice no one is using full throttle lol

and i have not yet seen a rc helicopter self destruct by reason of resonance since people that have never tried it are making a big deal out of it.

see the thing is when your using a small helicopter and nothing is bent its not a big deal and if the little bird gets the shakes you just spool it down and fix the problem.

the reason most people have tried to turn to bench type setup is because of fear of crashing and they feel safer because the helicopter is tied down so it cant jump on them if they did something wrong.

one night i dropped my transmitter on the ground and the helicopter spooled up what save my butt was the bird was on the bench tied down .

everyman for his own poison is all i can say either way you go with bench or with out nothing is safe what can go wrong will go wrong Murphy law

Watch at YouTube

but now that my setup and hovering skills are better i may not ever use the bench again the fear is gone i finally know what im doing

but still setting up and centering the tail on the lazy Susan in rate mode nothing can compare.

Ground Resonance
My opinion "Hard Landing" A-stars are temperamental, Could of knocked the Blades out of Track.. Also can happen when you try to start a A-star with Pitch Lock not Secured!! Not the case here of course. Hard Landing. There is a Spring loaded weight on the Mast and if the Springs Stick, This could also cause all Hell to Break Loose..

It seems that wether it be blades,no blades,full throttle or half throttle etc , people that tie down a heli are oblivious to the fact that a broken link or other small component is very likely to end up sticking out of their or a bystanders eye one day."

passengers disembark, and get half way down the steps, then the vibration came from outta nowhere?
Because the landing was top of a building, can a strong gust of wind start the oscillation like that?
If it ain't broke, go fly some more!

Why can the schweizer 300 suffer GR when it has shock absorbers on the undercarriage?I've seen photos of this heli destroyed due to GR after landing.

Because it only blocks the ones you have on your ignore list if you are the topic starter. Then the blocked can not post on your topic.

The shock absorbers can only reduce, but not totally eliminate ground resonance. The Schweizer 300 is prone to GR because of it fully articulated rotor head. Most Bell semi-rigid rotors are not prone to GR, by way of contrast.

there is little to no resonance when spooling up a helicopter strapped to a bench unless the blades are out of balance ,main shaft is bent etc.

so if there is no damage there is no danger unless you stick your face into the blades while it is on a bench and you have enough brains not to use full throttle and 13 degrees of pitch to a strapped heli lol.

I think this question needs a poll

* Strapping down a RC heli is completely safe and the best way to test setups.

* A good way to test setups but there is more risk of damaging the heli due to Ground Resonance effect.

* Are you crazy , you could put someones eye out doing that !

* You are a freaking moron and you will chop your head off when it desinergrates !

I would re-woord this option to sound something like this.....

A technique used in the dark ages of helicopter development that proved to be somewhat effective, but the risk of damaging the helicopter and injuring someone around the helicopter outweight the usefulness of the technique.

What is wrong with just asking someone with more experience than you to test fly the thing? Why are we even discussing this? How many of you continually have to use a similar technique to "test" your helis? When are you going to outgrow it?

I will admit it, I did use the technique back in the day for my first heli. Now it is just a test flight and be done with it. I'm confident in my building / flying skills.

aren't there alarms that tell the pilot that his rpm's are excessive when on the ground. or doesn't he have a tachometer with a redline on it?

in the movies it never happens

and that stand that W had in that video is so frackin stupid. traing gear is much more safer. you can't move heli around on a stand when trying to get experience.

this is me now .
bench testing is mainly used by beginners who are afraid.

but i have to admit i did put a small walkera on the lazy susan to check tail drift and tail hold before we hovered the heli and it was at low rpm and a walkera cant hurt anyone.

What happens is a caution light comes on that says, "RPM A Little High."
