Interesting 109F feature (Helicopter).

[je5ter]

I need someone to repeat my test on this and it could be as desired. I call this the Helicopter feature. OK it doesn't hove but it is very interesting maneuver you can pull. This requires some tricky skills and I recommend you use rudder pedals.

Take off in the 109F4 or F2 I found this easier in the F4. Climb to say 1500 to 2000 metres and throttle back while keeping the nose on the horizon. So gently keep pulling the stick back. When you start to stall and a wing drops DON'T USE AILERON TO CORRECT. Use the rudder to gain the secondary roll affect. Keep the stick back and use the rudder to keep the aircraft level. Be real gentle and feel the plane as the airspeed drops to some where I guess to less than 100Kph. Now if you are gentle just before you touch the ground drop the gear and bump you are down. I tried this in 1.32 and I think you could do it but the model is much more twitchy.

I tried this in a Spitfire and it has very different stall charactaristics. First when it stalls the nose drops no matter what and if a wing drops the rudder has so little authority it makes no difference. However in a spit you can keep it in a sort of glide/stall combo using aileron all the way down.

I think you do the same with the G6 but the E models and the FW 190 just drops a wing and spins.

Give it a go some one.

Not me. I crash like a stone.

Hmm me thinks I need to video this.....

[DOC]

not going to be part of this dev. cycle

[je5ter]

I realise that DOC but at least you can investigate and decide if you need to take any action in a later release.

Here is the video alas my commentary is drowned out by the engine! Some would say that is a good thing.

DOC if you want a copy of the video I could put it somewhere you can download it and then I will remove it from you tube if you want.

That can't be right lol

You can hover the 109 now like people used to do with the P38s.

[Ogg]

There was no hover or rotation? Helicopter?

What you are seeing is forward movement allowing continued lift over the wings. The 109 "slats" give an increase in lift

From Flying the Messerschmitt Bf-109E - by Rob Erdos, Vintage Wings of Canada may 1998

"Roll control response became sluggish once the ailerons drooped and it exhibited considerably more adverse yaw. Again a mild buffet preceded a gentle pitch break, this time at 88 km/hr. 88 km/hr!? That’s 47 knots indicated airspeed. Now I was definitely skeptical. There was simply no way that this modest wing area was holding this mass of aeroplane aloft at 47 knots."

This is what you are experiencing no doubt.

The 109 was able to do this before, just like the P38...

That's nothing I can hover the 109 at zero airspeed. Always have been able to do this. In fact in this video the 109 is still gliding forward with slats out thus more lift. Looks like it's working the way it should now at low speeds.

Didn't realise you could do it before.

Well I am impressed with an airplane with such a small wing area, no flaps only slats gliding with pretty much fulll elevator and no engine with nose on the horizon. It is tricky in roll but I wouldn't expect it to behave like that.

But as I said to DOC this needs proper investigation and then a decision made. I am not saying its wrong or right just strange and needs investigation and comparision with the flight model.

I wouldn't expect a P38 to hover either, but it does. Nothing out of the ordinary for this flight model.
