FSX Aerobatics: Question, can this be done?

Hi!

After training aerobatics in FSX and watched many videos in Youtube I found this but I can't do it with any aircraft (SU26, E300S, Z50L, CE1/2).

Is there some experts who can do it in sim, or is it impossible with FSX ?

I don't believe any of the default aircraft can do things like that. It is possible with certain payware planes, but requires that autorudder be off. If you don't have rudder pedals, you would have a very hard time getting it to do what you want.
 
The best try I have is with Extra 300S

BTW: I asked from real aerobatic pilot in youtube how this can be done, he answered like this. I hope this helps you to do it.

The simple answer: Yaw Left and Push. However, there is a lot of finesse to get it right.

The pitch stability of the airplane would normaly prevent it from tumbling like this. The secret is to get the airplane flying "sideways" so the oncoming air does not inhibit the forward tumble.

You start by yawing left to produce about 30 degrees of sideslip. Then you push forward which produces a gyroscopic reaction that yaws the airplane even more. Once yawed, the airplane can tumble freely.

Some of the WWII fighters that I Did FD's for were capable of this manuver even if the real ones might have screamed a little at the idea. The video's did not give a very concise idea of exactly what they were doing, one needs to be viewing outside the plane (from the ground) to ascertain that. My view is esentially a stalled condition, an agrivated spin maintained in a non verticle direction with insufficent stabilizing airflow to counteract the rotational inertia of the initiated manuver, whether forward tumbling or rotational about the longitudinal axis.

Start out with snap rolls and see where you get.

Good luck.... T
 
Yeah this is possible. I'm not an expert but more someone who just likes to push every control to it's limit to see what kind of spin the plane does next :mixedsmi:.

Unfortunately, FSX's simulation starts acting weird as soon as you go backwards (as in, after you did a 180 degrees front tumble) and starts pushing you up, while you should be going down. FSX doesn't like it when fixed wing aircraft go less than 0kts. You can see this too in the "Rudder Madness" movie which Dangerous Beans posted.
 
I watched Smoothies video again and I noticed that he didn't do it right (I think). Because I think maneuver is done only with rudder and then push of stick.
 
you have to pitch up snap it left and kick the rudder, you'll have to hold the stick i believe or you'll flat spin and not tumble... :icon_lol:
 
Alright guys,

I fly an extra 300l as often as I can out here in Texas, and while my recoveries aren't that good, I can at least start tumbling with ease.

The only aircraft capable of doing it cleanly in FSX is piglet's Zlin. The default extra is just a little to screwy. The IRIS eagle may be capable too, but I haven't tried it.

The easiest way to tumble in sim is to perform a vertical maneuver to a full stop, then start a 45 degree downline knife-edge. Once on the downline, start yawing the nose above the horizon until you're vertical again. You should still be more or less on a 45 degree downline still. Fight the yaw and pitch to keep the aircraft squared off. You can then add full pitch authority to start the tumble. Just as in real life, you're only likely to get one or two off before the aircraft starts to gyro-stabilize. It should resist then snap around once or twice. There'll be some flopping around after, but if you practice you can exit on the downline.

Disclaimer: Some here can start the "tigisfat doesn't know what he's talking about" stuff again if they want, but I'm just trying to help. Try it or don't try it, but the FAA says you can legally log my ground and flight instruction.:icon_lol:
 
Smoothie, you clearly show a proficiency for clean aerobatics, but I don't think that qualifies as a lomcevak.
 
Tig, aerobatics are the only things i fly in FSX, in Air cadets as a youngster i got told to "be gentle this ain't no extra 300" after trying to knife edge the Grob Tutor :icon_lol: now my hobby real world has shifted to flying, just suspended under a canopy (no not the glass or perspex kind) :icon_lol:

Pitching first and then yawing over will not produce a lomcevak, it'll produce a snap roll. Snap rolls, tailsnaps and other maneuvers are AOA funtional; the tumble is not.
