This is my first gasser. DL-50. I have been flying Satio 100`s about 9 yrs. I got this plane 2nd hand. I started it up the first time today. I have to tell you, seeing the power this thing has is scarying the daylights out of me. When this thing started it does not give much warning and you better be out the way. Hopefully i will get used to it after i clean my under pants a couple times. The question i have is that the idle is not as precise and consistant like i am used to with glow. When i set my idle where i want it to be; low enough where it does not kill. Then i rev it up and run it for a while from half throttle to full throttle then back to idle. It will not stay in the exact idle position where i set it. Now i forgot to say that this is all while the planei s tied down. The engine is broken in. When you idle it back down it may be a little high or too low. Not much ; but enough to have to play with the trim every time when you come back down from half or full throttle. Is this the beast of the 2- stoke gas, and is this normal? I am scared that at landing it won`t go to my set position and it will dead stick because of being too low ,or will overrun the runway being to high. I don`t want to be fiddling with the throttle trim and trying to land. Thanks
