Just looked at it. Coil looks okay. Maybees the it did overheat. Don't even know what brand it is. Using an 11x6 prop for break in.
Engine seemed to lean out just a little. Did the pinch test (pinch fuel line) and engine almost died. Which tells me its a bit lean so I cranked the needle a few clicks towards rich. Seems that the magic area is about a few clicks towards lean from the original 3 full turns. I still need to run a couple more tanks through it before I attempt to demolish the SOB! LOL!!! Too wet today to be foolin around with glow stuff and its also windy. My brushless wing though flew great in the wind! Its a great windy flyer as the wing planform is thin. Oh, would an OS # 8 plug run okay with byron's 15% in this super tigre? I run # 8's in everything except my Saito 4 stroker and the Evo .46.
