Does anyone have any webspace so i could host the 300kb film?
I don't fly the spit14 often but when trying to perform a loop i got stuck at the top i floated down inverted from about 6k til 2k until i finally recovered trying everything i could think of(it didn't hit me to try use flaps til nearly too late). Is this normal behaviour for an a/c? i've never done this before that's all. Then i promptly Ho'd the nearest a/c and died.:D

thrila, I'm not sure if you use combat trims or manual trims, but the phenomenon you experienced effects all planes in AH - the deadly inverted flat spin.. :D !
When you go vertical up to too low a speed, then there's always a chance the reversal process gets screwed, and the plane starts to pivot on its yaw axis more than its pict axis.
The results are catastrohpic - the plane begins to fall down and lose altitude on backside. Some planes have a better chance to recover from this(like the Spitfires and 109s), but others(like the Ta152 or the P-51D) are very very hard to recover from it. Most often they auger straight down.
Now, I came to realize that the use of manual trim(especially elevator pitch in the neutral center position) lowers the chance of falling into a flat spin. Since combat trim does not react to the status of the plane, but rather is just a preset figure of trim values according to the plane's speed, when your plane goes vertical into extremely low speeds the elevator automatically trims almost full up. I think that results in a state equivalent of pulling the stick too hard at too low speeds - thus, during the vertical, with the elevator trim way up, the plane cannot reverse nose down in a natural manner and it falls into a spin.
However, when on manual trim, with the elevator trim centered, in most cases you can just ease on the stick and the plane flips over with ease.
To the Spit14, it might be especially dangerous in the verticals due to its massive torque.

Yeah that sounds like it. it really didn't feel like a spin tho, it more or less fell straight down like a rock. on film in the 35-40secs i fell i barely span 180 degrees by the time i recovered, at the time it happened it felt like i wasn't even spinning at all.:eek: Yes i had combat trim on too so from what u said that didn't help.
I was really peeved! the sortie before i died from 1.1k from a spit...1 ping and BOOM! then this sortie i shot myself in the foot by falling to the deck like a stone with 3 cons about!:D

Might have to do with the way stalls and spins develop in AH. In most cases a flat spin is a very rare thing, and most of the times the plane just falls down like a helicopter, not spinning, but with some tilting and rocking it just... goes.. down, straight down. ;)
However, in IL-2 I've seen a lot of the deadliest of the flat spins - the plane literally stops almost all movement forward, and it spins on its yaw axis, touch down to the ground almost like a UFO!

Lookee at my signature. The picture hangar supports zip files as well.

Thrila, try the same without Combat Trim. I know for sure that when I tried CT in the Typhoon it would often put me into a flat spin. I always use manual trim now.
