Hi agexpert,

if you haven't already got one i would recommend a tach its a must,Hobbico makes a good one and its common at most hobby shops and allot of Patience when breaking them in.

The adjustments are very minimal much more toucher than a 2stk, run it on the fat side...typically what i do is tach it wide open and drop it back 2-300 rpms let it idle down as you would your 2 stk and slap the throttle there should be no hesitation and then fly it hi in case of stall on break in... good luck... Hope this helps

I run omega 15% 30/70 castor/synthetic blend fuel
