Yes, I know what you're talking about. The plane is remarkably consistent in how it noses down and rolls at the top with power.
I'm talking about something different though. Imagine the aircraft going vertical, hitting the top of the climb slightly past vertical, and being unpowered.
The aircraft noses over the top (falling with wings inverted with respect to the horizon). However, the aircraft has NO forward airspeed.
At this point, the aircraft has its wings more or less level with the horizon (though inverted attitude so the ground is "above" you). It is not going forward, it is falling straight DOWN, but with nose pointed at the horizon. The aircraft's nose also yaws in one direction with a predictable (though rather slow) frequency. You can get out of this by simply turning on throttle.
Have you ever found any application for something like this?
Yes yes yes......you have discovered it. This is how you control the turn at the top in very slow rolling scissors.
What you are doing is bunting the nose forward just before the plane has zero airspeed. You need enough speed to still have elevator authority. The plane comes to a stall upright and if done correctly will fall out of the sky into a canopy up flat spin....like spits do.
In a series of vertical rolling scissors...the kind that develop on the deck, you go up and try to roll over and come down with a shot. Typically the bandit is at the bottom of his dive and is trying to pull up for his rollover.
When this is happening you usually have very low airspeed on the top. EXACTLY the same thing is happening here as if you were practicing the way I said. THe difference is your doing it over and over on each scissor.
By getting your nose up to almost vertical and holding for the stall you can bunt the nose forward, roll left and push/jam the throttle on. This flips the plane over and down. You use rudder...sometimes opposite (right in this case) to help stabilize the maneuver.
If you pulled to vert to zero and let the tail slide you will go into a falling spin. Easy to get out of but you loose a lot of alt recovering and loose sight of the bandit and loose any position you had.
If you stall as you describe you can flip over to guns, shoot, nose back down for speed and up again, on the way back up you pull the throttle off, bunt the nose forward, slam throttle on and get guns again. Sometimes you are so slow doing this kind of scissor that you have all flaps out and wep on using every bit of lift and power you have. If you pulled the throttle off now you would just fall out like a rock and crash. So you do the same thing but count on the tork to roll the plane over...and it will...you also have to use full left rudder to speed the "tork roll" up. Sometimes you do have to "work" the throttle on/off different amounts to control the plane. If done correctly you can use just the engine and rudder to make each vertical reversal. The amount of tork you use and amount of rudder is dependant on where you want to go. Its a balance. If you manage to low wing stall and snap the plane doing this you can easily spin out of control. It is necessary to use the rudder and different amounts of power to control the plane. With practice you can do it so good you can make the planes nose point anywhere you want.
If you pull to vert and go over the 90 deg mark where the canopy is beginng to point toward the ground and then stall with the canopy 20 deg over the top you will go into a falling roll...you can convert this to a "falling leaf" if you control it.
THis is a kind of modified tail slide where the plane begins to slide on the tail slightly inverted but the plane rolls as it falls. Again you can use tork and rudder to do get your nose pointed where you want it. This is a no airspeed maneuver and you loose alot of alt but there are times when it is useful.
