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.

Mahmood, LSA stands for "Light Sport Aircraft". - An International standard set up to define acceptable marketing standards for light sport aircraft, including Gyroplanes. It is intended that gyroplanes built to comply with these standards would be accepted world wide without having to undergo individual certification in each different country. Among other things, the standards define stringent safety and stability standards, to which the RAF without an effective stabilizer will not comply. Many experienced pilots have learnt to effectively control the stability shortcomings of the RAF (and some other gyroplanes) but there have been many lives lost trying to gain that experience.Beginner's quotation - "I hit a bad gust of wind just as I took off"Tim McClureBroken Hill

Does anyone have any objective evidence as to the effectivenes (or otherwise) of the RAF stabiliser in comparison with the usual type?John EvansThink logically and do things well, think laterally and do things better.

I believe that Paul Bruty flew Laszlo's recently. Maybe he could comment on its effectiveness.When these stabilators first appeared, I contacted the RAF factory to determine if the device was fitted by the current owner of a RAF, that in the opinion of the factory it would still meet their requirements as far as hang tests and other specified limits are concerned. The initial answers were vague, and in the end I was told "For God's sake! It's only a trimming device".For what its worth.Regards,Waddles.

Hi Waddles, Laszlos Raf was in his shop getting an ej_25 fitted.I have flown a Raf with a stabilator (the beautifull one for sale in the gyro news) and all it does is act as an aerodynamic trim, also as the speed gets faster makes it more difficult to move the stick quickly. On the ground there is no trim spring pressure to push against to hold the stick forward. That is great. The Raf have used an incorrect torque tube offset and requires a lot of trim pressure when flown dual, so the lack of trim spring pressure on the ground is a benifit. I couild not find anything positive re stability with the stabilator. Every time a gust was encounted the machine would diverge in pitch if left hands free, and a PPO would ensue.The Raf stabiliator is an aerodynamic trim that makes it more difficult for the pilot to accidentally give too much pitch input at high speeds. Not even a good "bandaid" measure to the large thrust line to CoM. An effective h/stab is a far better "bandaid".Raf owners, conduct our Raf mods and have an almost perfectly stable gyroplane.Laszlo conducted my flight review in David Browns modified Raf that was signed of by Adrian. I trimmed it and took my hands off and we flew through rough and smooth air and the machine was stable. I took David after Laszlo had completed the paperwork. We conducted the stick free stability tests at 65 mph. The first round of tests showerd that the machibne slowed down more that the 10% allowed by the stabdards when full power was applied. I reduced the negative AofA of the stab approx 1/2 a degree and the following tests were perfect for thatr TOWeight. Trimmed at 65 s/l hands fee, apply full power and the speed would increase 2 mph and then the nose would rise and the speed would stabilise at 65. The same with reducing power to idle, the machine would slow a couple of mph and then the machibne would lowers its nose and settle into a glide at 65 mph.Flew as cross country instructor this morning in the Magni, the only gyro that I have flown that surpasses my Hybrid for stability.
