Brand new Moki 1.8 using FAI fuel (80% meth + 20% BeNol) spinning a Bolly 19x8 CF prop delivers a solid 8100rpm and peaked to 8400-8500 rpm on the bench after 2Lt break-in. Wow this engine delivers some thrust and it's so easy to start on a back flip provided that Moki plug has to be cranked up to about 4amps. On the bench it's a dream, we'll see how it goes in the plane (GSP/CMP Katana 72") this weekend.
