REALLY fast planes off water?


I love fast planes. I have fast electrics and fly turbines. I am wondering if there are any crazy fast planes for flying off water. I don’t really want to fly a turning off water though. Anything in the 130-150mph range?

You can look for plans for old Schneider Cup racing planes that were flown in the 1920s and 1930s....some of them were very fast for the times.

Years ago I envisioned a fast flying float plane with floats that retract tight to the fuse,, never built it but it was awesome in my mind

If you are looking for a really crazy challenge the Piaggio P.7 It never flew in full size, but models have flown. Its a hydroplane- seaplane, really wild design built for speed. Used a boat prop to get up out of the water before the air prop started to turn.

IMHO the design with the best speed potential is Laddie Mikulasko's "Arrow"—a delta, like the yellow one pictured above, but without floats. Instead it has a single float/hull (picture a retracted center float) and the engine in a pod attached to the fin/rudder. If I were going for straight-line speed, that would be my first choice ... I'd probably lower and lengthen the pod & use a fully piped .40 with a 7-1/2" prop. 6 inches pitch, 25,000 rpm, that's about 150 mph, right? Or close to it, anyway.

Arrgh, stop me before I start gluing!

Seriously, I was just saying that's what I would do. But there are plenty of good choices of electric power in that size range. Might have to use a glow-engine prop, though, depending on the rpm.

Yeah, seems like for electric he could pick up a pylon racer and add floats, heck a EFXtra would probably easily do 110, and modified probably 140+...

Hah! I love noise and smoke. My jets are for that. Mainly I don't want to fuel planes on my boat. Also, 25K RPM is way easier with electric.
