OK, the Sail 12 x 6 turned 9,980 on the black 50,the problem was I could not find a LS needle setting with a good idle and good transition. I cured that problem with an nearly broken in Saito 62 that can idle at 1,650 and then turn at 10,150.

Fuel Wildcat 2/4 10% with 18% full synthetic

Plug======Glo-Devil 4c Special for Enya and Saito
The 62 has about 1.5 hours total time.
Idle 1,650, will be flown at 2,200
Max rpm============10,150
