There are a few single seat gyros that have used the bigger Rotax 912 engine. I have only seen two and heard of another.
Roy Davis’s single seat hot rod is a very small compact machine with a 912 that he does his amazing demo’s on. It’s rate and angle of climb quite amazing, but then Roy is an extremely experienced and capable pilot.
Over here in the UK I have seen Steve Hart’s 912 Merlin. I gather that the static thrust test on that was around 390lbs, and apparently, that was not the only one around.
Nicolas has put a 912 into a single seat Genesis but not much information on how that worked out, though I have no doubt is was done correctly and was safe to fly.
Why would one want to do that. In Roy’s case I would venture the increased performance that would give him, but there could possibly be other reasons though is is debatable whether these would be completely valid.
Operating from high altitude locations, or flying in areas where climbing over high terrain might be a regular thing. Also being a 4 stroke the decreased fuel consumption over the fairly thirsty two strokes could give greater range for single seat touring.
The problem being the trade off of the extra weight of the 912 and all it associated hardware against the useful load of pilot and fuel on the 582, the extra cost of the engine, and, the potential hazards the extra power might present to the pilot.
Not many have done, some have expressed an interest in doing it, was wondering if some of our more technically savvy Forum members might offer us some insights on the matter.
