Volga Hydrofoils Messageboard

My Project has finally come to an end
Boat is in the water and fast needs only to be fine tuned
The complete project has been added in PDF.
I now have figures on max speed but before fine tuning:
55 km/h 30 knots and fuel consumption < 13 l p/h
At 40 km/h and 3500 rpm < 7l p/h
My range is now 1480 km at top speed and >3000 km at 40 km/h

Maybe something is wrong with the propeller, gear ratio or wings. With the engine ZMZ- 511 speed of 3500 rpm is about 55-60 km / h . In 4000 rpm about 70 km / h

hay, if you have the single propeller 280, forum member Mark Boom has a spare prop.
He have installed the twin prop.
His prop is in my barn,near Amsterdam.
Can be good for adjusting the pitch.
Of maybe is is already beter.. markboom@dds.nl

keep them flying!
