Asked Sundogz how far he was with his waterjet-outboard...
But that project is parked for other waterjet related projects.
So this is the only waterjet outboard in RC I know of.
Well done!
The concept is perfect, since bevel-gears always consume power due to the relatively high amount of friction.
Than again, true scale outboards from Yamaha and Mercury are 15% less efficient than the version with a propeller and bevel-gears.
Those use a centrifugal pump as well to avoid the bevel-gears.
The Russian development was a true axial waterjet-outboard with bevel-gears!
Wonder how that will work:
The inventor of waterjet propulsion, Hamilton from New Zealand started with centrifugal pumps, but abandoned those early for axial impeller pumps.
Ik heb het youtube kanaal inmiddels van de Duitse ontwerper gevonden, maar is er ook een website van?
Of een forum-thread ergens?
