Well first of all there is no reason to go full pitch. Three or four degrees is fine. How does holding the boom give you any advantage for tracking?

I am hoping this is a joke and no one has actually tried this.

I'm afraid that's no joke..... it's in both the original and most recent revision of his manual..... I don't think he recommends to go to full pitch but even at 4-5 degrees of pitch, you're certainly in the "full throttle" range.......

Though I've not __personally__ seen a heli actually "explode" while being strapped down, I HAVE personally seen someone try this method resulting in very violent vibrations/oscillations....... had the throttle not immediately reduced to idle, I'm sure the heli would have come apart !!

Seeing that whole scenario FIRST HAND was enough to tell me that this procedure should not be attempted.......

I know that some will argue, "I've done this myself many times without any problems" and to those I would say, "congratulations"....... for getting away with it..... It will take you only one time to make you change your mind !

I would never recommend that procedure to anyone, period !

well this was common circa 1979 when hovering was an accomplishment. There were no simulators so you learned to hover by hovering your model. If you couldn't hover, you couldn't hold it in one place to see which blade to adjust.

So ONE way that was popular, was to hold the tail boom to keep the model in one place, lift it into a hover and look for an out of track blade.

It was incredibly dangerous then and it still is. Not recommended for anyone to do.

So you're saying people back in the late 70's lifted the heli up with the collective to eye level while holding the boom with their right hand for example so they can eye the blades for tracking?

No hands on the cyclic while doing this and just "muscle power" to hold it level with the tail boom grab that they had on it?

Some scarey chit for sure! Maybe that's how helis got their nicknames as...

"choppers!"

The pictures I've seen show the folks holding the heli by the vertical fin while doing that procedure.....I'm surprised no one has posted a pic.......

I'll see if I can find one...

Yes, of course I have witnessed this myself! I will guarantee that something is out of whack in the head or a frame member is cracked or broken when this happens. Obviously if this should occur you should stop immediately and start looking. You just proved your heli is not flight worthy. It will not happen if the heli is fit to fly. So for those of you who think it is dangerous then the odds are you have flown a heli that is not fit to fly and you didn't know it.

Some people have a death wish. It is hard for me to believe someone would think it makes sense to do.

My Posts This: Topic  Forum		Wow, the people I hung around with when I got started in 84' would never dream of doing something like that. I got scolded for hovering my GMP Competitor higher than 6" after my first week with training gear. Safely was key with those guys.

Unfortunately, some people will always be wreckless until an accident happens.

Take the following as an example of some pretty poor judgment. I just found this by accident on you tube.

I don`t know that kind of material, but even though it`s called
gasket paper, I hope it has the same thickness as the original
gasket, atleast be sure that you can turne the engien by hand,
in case it is paper thin material.
Don`t worry it`s only the first few gaskets that takes some
time, it get`s easyer

The material I've used feels better than the supplied gaskets and it’s rated for fuels and up to 250c, if these don’t work I'll just weld the carb on

Yes ofcause, it`s for a carb gasket, not a topendend/crankcase
gasket ( then it don`t make much sense when I say "atleast
be sure that you can turne the engien by hand" )

So far so good
Early days but the home made gaskets are holding up better than the stock gaskets, now I have to tune the needles again
