As Mahmood is joining in our forum for information we should give him an explanation for Nick's remarks.It's pretty obvious that all other aircraft have a horizontal stabiliser, particularly helicopters, which have it on a very long arm. It should be understood that its stabilising effect is directly proportional to area, but proportional to the arm squared.RAF have actually brought out an optional stabiliser, a wing mounted on top of the cabin, it is linked to the rotor rather than the airframe, I understand their reluctance to accept the usual airframe stabiliser has its origin in a legal dispute in which they were involved.Location of the stab in the prop blast also makes it more effective, but there are very stable machines with the stab outside the blast - usually on a very long arm.There is some very good stuff on this topic elsewhere on this site.John EvansThink logically and do things well, think laterally and do things better.

Mahmood, The fact is that the RAF 2000 will not pass the new LSA gyroplane stability standards without an effective horizontal stabilizer. When the standard is enforced in Australia, a RAF will not be able to be "sold on", until it complies - including your instructors. An RAF can give the illusion of being stable in the hands of a good pilot, but have you ever noticed that you have to give constant attention to the joystick?Beginner's quotation - "I hit a bad gust of wind just as I took off"Tim McClureBroken Hill

Interesting pictures Mahmood!If you go back to the home page and look under "Technical" for an article by Jean Foucade on "Stability" you should have some interesting things to discuss with Lazlo![:0]I will leave it to Tim to explain LSA.John EvansThink logically and do things well, think laterally and do things better.
