Chinese ST have 4 digit No stamped on mounting lug edge . ( Wheter it says made in Italy on NOT . usually CHINA inside backplate .Itl Components Ass in China have the stamed lug ) My preferance is Italian , tho Ive one Chinese . Shaveing the bar over the bypass ( And Maybe the ' G ' , )
makes screwdriver access far better .
A Top flite wood 12 x 5 will work good , and BETTER cut to 11 5/8 in. as youll get ' The Break ' good with that . If you cant find any 10 x 6 3 Bl Tornado's .
Should have 3/4 turn full 4 stroke to clean two stroke , Warm Up , needle in to full 2 , back out maybe 1/4 , to the brrrp brrrp bit , Itll be near correct .
Tend to run muffler pressure .
the ten ton Silent Mudffler works well . No power loss . Will haul a ten ton plane , load gets ' the break ' working A1+ in my opinion .
a 4 or a 6 inch pitch , is not a good idea , in my experiance . Tho theyll waffle along quitely on a 12 x 6 , itll take a bit to get ' the break '.
First Few gallons 23 % oil . 18 % 50/50 after , unless your in boiling weather . Dosnt really need nitro . tho 5 % is plenty .May run better without it .
