PAW "Classic .80" SBR model diesel engine

[NOTE: RPM figures are incorrect. Tachometer was set for a 3-blade propeller]

Shown in this video is a PAW 80 Classic from the late 1990's. It is of 0,8 c.c. (.049 c.i.) displacement. The "Classic" version PAW's are no longer made.

It is different to the standard PAW 80 in that it has cross flow porting with a single exhaust port, in this case oriented to the starboard side. As delivered the exhaust port faced to the rear.

It is pulling a Master Airscrew 8 x 4 propeller. The engine is timed and ported for high torque, low RPM application in vintage type F/F and R/C aircraft. After adjustment it throttles very well on the supplied PAW R/C carburettor.

Fuel composition: Equal parts Di-ethyl Ether, Castor Oil and Kerosene plus 1.5% Amsoil Diesel Cetane Boost.

Propeller: Master Airscrew 8 x 4.
