odd-sounding Varieze in FLL

[crash-proof]

I would let this be, but now my curiosity's got me. Anyone around FLL Executive know about the Varieze with a very hi-reving engine? I've seen this thing circling endlessly around the neighborhood, several times a week, and the sound is, to say the least, very unique! Sounds like a V-6, coupled to a 3 blade. Man that thing shoots into the air on TO like a bat outta he11

Maybe a Mazda rotary engine? I know a guy here who had one in his Vari EZ, until the engine melted a few bearings on him.

I've seen some pretty strange engines in experimentals, so maybe it's just a high revving engine. Most vari-eze's and long-eze's sounds kind of funny because, with a two bladed prop, both blade hit the turbulence off the wing at the same time. It causes a lot of noise and a lot of stress in the prop. It's the reason why you will never see a metal prop on a canard pusher.

Naw it was definately a hi-revvin motor, you could clearly distinguish the prop sound and the engine, which whined louder than the prop. Could have been a rotary alright, I think I've heard of those on variezes before.

Could have been the ducted-fan Varieze.

If you could hear that the engine and the prop were turning at different speeds, it was probably just an automotive engine driving the prop through a reduction gearbox.
