Bear with me
« on: May 26, 2011, 04:03:02 PM »
I watched a few clips of Tumbling Bear's shows and it's some really impressive stuff  |:)\
but he narrates from the cockpit, and I just want to know at what point do aerobatic pilots get over saying "WEEEEEEEEEEEEEEEEEEEEEEE"

He explained to me how he gets that airplane to tumble but I wasn't able to follow 100%.
My favorite part is when he goes straight up and then tumbles on top while disappearing in the smoke. All you see is a little yellow tumble around in the smoke until the plane "falls" out at the bottom.
Very cool!

Lomcovák.... or Talířek, maybe, as it seems done from vertical... First shown in 1964 by Ladislav Bezák in Zlin 226 Trener, it is apparently some kind of negative snap roll, or so I have been told, ending either in reverse spin or tailslide.

I've heard that Lomcovak tanslates to "Headache"  :)

I've seen the description of how to do it.  as I recall:

1.  pull up to 45 degrees.
2.  let speed bleed off to near stall, slipping with right rudder, left aileron.
3.  near stall, apply full right rudder, right aileron, up elevator to enter a snap roll.
4.  at 180 degrees roll, fully invertered reverse the elevator to full down, apply full throttle.  The aircraft should swap ends so it's going up, backwards at full power.  :O
5.  Hang on tight till things stabilize to an inverted flatt spin.
6.  Recover from inverted flat spin into vertical dive.

Never tried it from the cockpit, and could never get the timing right with an R/C plane.  ;)

I dunno . . . .

Any manuever where you "stabilize" into an "inverted" flat spin seems to be something I would probably try to avoid for my whole aviation career......

Almost sounds similar to when I learned to hover a helicopter....

I found a couple of short clips on YouTube too, looks nifty. Also sounded like the female presenter in one of the videos herself was a pilot. Is is also true that some of the se civilian propeller planes can pull as many g's as a supersonic fighter-jet? At least ones without thrust-vectoring.

I think the female presenter is his wife. And yes, she is a pilot as well. She owns a super-sweet Turbo-Commander.
As for the G's, I think 6 or so is not unheard of. I can ask the bear though....

+6/-3 is what our aircraft's rated for (aerobatics from '30s), but I've seen modern VLA's with rating of up to +9/-6, so also fully aerobatic...

Wow, as much as I would want to hitch a ride on an aerobatics plane one day, I think I would puke within 10 minutes max. I don't know why my brother doesn't get sea/car/airsick but I do. Quite unfair! Recently I heard that seasickness is associated with allergies or histamine intolerance etc... Anyone know more about this?  ???

I get sick when I'm a passenger in a vehicle that's controlled in a maner I find unsafe, especially if I don't know/trust the operator of the vehicle.
