Thanks.
You make it sound like an art Mike, which it is. ! I am most dissapointed if the engine is not on song in flight.I feel robbed of the speed fix and adrenaline!
A click either way for optimum is the difference in a truly contented speed freak.!

Out of 211 flights on the magnum, I can maintain excellent rpm from launch to finnish but notice the next day that setting needs a tweak.

My mates make snide comments if the engine isn't on song throughout the flight, claiming it sounds rough when rich and leans at the end.!! But what do those slowboys know! Ha The big girls, dont help me launch, so its down to me and thats why I need the power on tap from the onset. Ha but i can vertially launch vertical on the magnum with 9x7!
Having something to hold on to is a help in self launching, A skid for SD?



lean it till it siezes, was my saying!
Makes me think if castor is good for lean runs then lean herr right out if she can take it!


If the pipe/header setup is too short for the prop being used, however.. then yes, you'll munch plugs and have fits because you'll have a heck of a time finding a needle setting lean enough to launch without cooking the engine as soon as it unloads and wants more fuel.

This could explain why my needle is only half a turn out?
