Hi RV4ker The engine is a gray import 2l Toyota turbo diesel that cost me under 4K. Reduction is standard pulleys from Bearing man or any bearing company that has been re-machined to accommodate the center hub and bearings. A Gates or HTD 14mm x 55mm wide belt is used. This can handle approx. 130kw....

What do they want to know?

Approx. 75 Hp from the motor.
Reduction: 1.7:1 14mm pitch gates belt drive
Propeller 72 x 48 fixed pitch
Peak RPM 3200 after release
Climb rate 700 f/m at the coast.
50L use-able fuel will give you about 5 hrs of flight ( tank 60 l )

Wat nog?

Fuel consumption is 9l / hour confirmed over the last 60 hrs of flight.

It was a bit of trial and error but as can be seen on the pictures it fits nicely. As far as SACAA is concerned, they did not query anything as far as t...

Hi Guys Let us try this. Johan de Graaf asked met to comment on the Piets with 2C turbodiesels. It sounds a lot easier than it thinks. The reasons for the diesels are simple.
