I,ve been flying helicopters for about a year or so now and decided to get a plane for something a little less stressful. I had a plane a long time ago but got rid of it for lack of place to fly. My new found plane , so far, hasn't been that relaxing. I built a Lanier Stinger 40, it's powered by an Enya ss40 with a 12x7 prop. I've tried fueling it with Cool Power 15% (thats what I run in my heli). I tried a first flight the other day and spent about 4 hours trying to get off the ground. I leaned it out, richened it up, changed to larger fuel lines, it just doesn't want to gome off the ground. I was in a large sports field and had about 500 feet of runway and was using it all. Being a tail dragger, as it went down the runway the tail came up as expected, when the plane got to what is aparently full speed I gave it some elevator, the tail would dip down, the plane appeared to get a little lighter, but that's it. It continued down the runway just bouncing on the grass. Not hopping like it was trying to fly, just a little bounce..

My question is..... should I be running different fuel....... or a different prop.......... different engine....... I'm not sure where to start.

Any Ideas?
