View Full Version : The Most Amazing Thing I Have Ever Seen....

This has NOTHING to do with beginning electric flight, but I just had to share this with you guys.....

I live in LA, and there's this sanctioned AMA flying field in the San Fernando Valley near the Sepulveda Dam. So I decided to drop on by just to see what was going on.........It looked like a festival going on.......huge tents, huge semi tractor trailers.......something big was happening.

Anyway, I found out it was a Heli-Fly in, and all the factory people were there showing off all their product and flying expertise...........and apparently, they had a bunch of the top factory pilots there from all over.......

There was about 8 guys on the line and all were doing some amazing stunts with their gas helis, but..........there was this one guy who did things that I didn't think was physically possible in this universe. The heli that he was piloting seemed to defy the laws of physics. It was a big machine......had to be about 5 feet long.............so here he was, just doing all the incredible stuff that everyone else was doing.......flying inverted, loops, crazy spin-overs, etc etc.......but then......he brought it right in front of him about 3 feet off the deck, stood it on it nose.......hovered there for a bit, and then...............in the nose down position, he accelerated from a dead stop to what seemed like 100mph in the blink of an eye, and then came to a dead stop all within about 10 feet.....and then he did it backwards and then forwards again.................I don't know if I'm explaining this or if you guys have ever seen something like this, but I was dumbfounded.............Like I said, it seemed to defy the laws of physics...........to accelerate that fast from a standstill, and then come to a dead stop within a matter of feet. And the weird part is that it didn't slow down to a stop. It just........stopped......like it hit an invisible wall. He did this back and forth within a 10 to 15 foot range. It didn't look real. It looked animated.............Simply amazing !!!

Cal - about a month ago, by chance I showed up at a local club field here in Belgium. Turns out that one of the members is the Beglian national heli champion and was there that day testing some new heli's that companys that sponsor him give him. He did the same things you described. I was in shock and had the same thoughts you did - what happened to the laws of physics. It was amazing and impressive.

Good stuff but belongs in Heli 3D which is what you witnessed. :)

Sounds cool... Are non AMA spectors allowed? I live pretty close by and would like to check it out sometime.

Can someone out there PLEASE show us some video of this stuff? I would love to see it!

Yeah, lets see the vid of how to make a travel worthy blue canopy

BTW nice flying this last weekend

Thank You. To bad it had to get broken Sunday, but its all flying again. Got it fixed today and tested it before I leave for NJ on OC Bobs funfly.

Yeah, Alan, it was blue..............great show.......!!!

I orginally posted this over in the Electrics Forum and it got moved. That's why I never responded.......Never saw it.............

Anyway, take care.........Great flyin'..................

Cal,

Are you talking about Tic Tocs? Where the heli ascends very fast flips over inverted, stops and goes back to where it was before it ascended and then does it repeatedly

No Tom..........Although impressive, EVERYONE was doing those.........

What Alan was doing, NO ONE else was doing...........He did Tic Tocs too, but then, like I said, he would bring it down right in front of him, maybe a few feet from the ground, stand it on it's nose, and go from left to right and then right to left while the nose was still pointing down is such rapid succession and within such a short distance of say 6 to 10 feet, that it looked animated rather than something that was actually happening.

Hope you don't mind the thread bump, but does anyone know where I can see the Las Vegas Fun Fly of Alan Szabo, Jr. 2004 video - beside www.muchosucko.com? (They have the nerve to put their crap all over it.)

The LA vids are great. Promethian effort, Alan!

http://www.muchosucko.com/video-alan-helimaster.html - this is the exact link. sorry for linking muchosucko, it's tasteless as they say...

What kind of headspeed do you need to do stuff like that?

So no one has any idea what the head speed should be?

The funfly video can be found here: http://www.augustoheli.com/videostuff/videoarchive/AlanSzabo/default.asp

EDIT: Alan Szabo Jr. uses 1780, AFAIK.

He doesn't run 2000 on his R90. You can see it in most vids, the blades standing almost still with a fast shutter time. These vids are shot at 30fps, so that makes for a straight 1800.

I think it needs to between 2550-3000 but i am not sure

Um...this sounds like very bad logic.

If the blades are standing still when shot at 30 fps, then that means the headspeed is a multiple of 15.

So if the head is spinning at 15 rpm, then the camera would catch it twice per revolution so it would appear to be standing still.

If the head is spinning at 30 rpm, then the camera would catch it once per revolution so it's standing still.

If the head is spinning at 45 rpm, then the camera would catch it every 1.5 revolutions so it would appear to be standing still.

etc.

If you think hard about this, you'll realize that the Nyquist Sampling Theorem applies to this case.

I think the logic is pretty good. You're right about a multiple of 15, but a multiple of 15 revs per second, not revs per minute. Multiply 15 by 60 and you get 900 rpm. So the head could be going 900 rpm, 1800 rpm, 2700 rpm, etc. 1800 seems the most plausible, but maybe it is spinning at a crazy fast 2700 rpm, although that would yeild a tip speed around 700 feet per second, or 480 mph.

I'm not aware of any helis other than micros that spin at those kinds of head speeds. Most 3D guys seem to run in the 1800-2000 rpm range.
