I joined BadAim's server today (Wednesday night) and while flying coop, discovered an infallible way to avoid the notorious P-39 spin problem...
The technique is quite simple - get well above your target, and dive towards him. Ignore the shuddering, and start praying. As you exceed VNE, bits will start to fall off. Ideally, you will then lose one elevator, and one aileron. As you approach your target, ensure your shot counts, as you are strictly TnB now. Having destroyed your target (I got a Ju 88, honest), head for home. Do not engage enemy fighters, as your roll rate is about as good as the average oil tanker's, while elevator response is if anything worse. You can put in any control input whatever, with no chance of spinning, or indeed carrying out any manouvre that a fully loaded refuse cart couldn't. I didn't actually get to land as the server died on us, but I think it would have been possible, if not very elegant. There is a slight flaw in this tactic, in that you may lose other control surfaces instead, or indeed break up in the air, but the unorthodoxy of the manouvre, should you get away with it, is well worth the risk, just for entertainment value.
Seriously though guys, I had a great time. Thanks to BadAim for running the server, and to you all for putting up with the antics of a noob without laughing too much, and look forward to next time.
Andy.
Edit --- 'TnB' above should clearly read 'ZnB' - I'm getting my TLA's all mixed up again
