I flew a Jr. Flitestreak in control line precision aerobatic events, It was powered by a TD 09 and was fast on 57 ft lines. I had it balanced closer to the leading edge than to the spar, and about 20 degrees either way on elevator throw. It was very smooth and still flew squares and triangles nicely. Control line Flitestreaks with the single wheel gear as shown will really grease landings on hard surface. Glad you got yours sorted out.
