Well here is the Red Bull DC-6 doing a loop....at 4:10
Remember the 707 barrel roll?

Re: Remember the 707 barrel roll?
Even after watching it there, quite hard to believe that a DC-6 flew a loop.

Re: Remember the 707 barrel roll?
I'm not convinced it was a loop. The shift in perspective of the camera can be deceptive, and it would be very difficult to do a loop without exceeding the limit load factor for the DC-6, which is 2.5 flaps up, and 2.0 flaps down. Transport category airplanes have lower load limits than lightplanes. Normal Category lightplanes have a limit of 3.8 positive and less than that negative.
It would be extremely difficult do do a loop in any airplane without exceeding 2G's in the pull up and the recovery to level flight, the usual result would be to run out of airspeed before you get over the top.

Yeah, looks like a "Helicopter loop" where it looks like a loop but isnt.
But thats ok. The effort was made, and its still impressive.
Now about this 707 loop?

You can learn all the math in the 'Verse, but you take a boat in the air that you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps her in the air when she oughta fall down, tells you she's hurtin' 'fore she keens. Makes her a home.
Re: Remember the 707 barrel roll?
Watching a second time I see what you mean John. I too thought the wings would come off at the bottom of the loop. Also seems like pretty low altitude to start a loop in a plane like that.
Thanks,

Re: Remember the 707 barrel roll?
That's an aileron roll, and you can do that with one G positive all the way through. It's easy on the structure so long as you are at or below the speed for full aileron deflection. The key is to start the maneuver with a pull up pitch attitude that is equal to the down angle you will have on the exit, and not so steep that you get too slow on the top, and not so shallow that you can't maintain one G while inverted without a steep exit that may result in an overspeed. If you have seen the video of Bob Hoover doing a roll in the Shrike Commander with a water glass on the top of the instrument panel, that's a well executed aileron roll. There are numerous ways to screw the maneuver up so practice with your cheap airplanes first.

Didn't he used to do that with the engines shut down?jeaton01 wrote: If you have seen the video of Bob Hoover doing a roll in the Shrike Commander with a water glass on the top of the instrument panel, that's a well executed aileron roll...

Re: Remember the 707 barrel roll?
I don't think the water glass video was done with an engine shut down, but I think I remember him doing one with one engine shut down at the beginning of the roll, and with that one running and the opposite side shut down at the conclusion. Busy hands! I can't find a video of that but here's one of a full flight with a 16 point roll and both engines shut down. What a guy.

The mention of Bob Hoover reminded me of this old kit…
