Ed, the plane has a wingspan of 65 inches, one degree of dihedral, wing area is 744 sq. inches and a body length of 49.2 inches. With movement total of 30 mm on aileron, 40 mm on elevator(I probably only use 20mm, 10mm up and 10mm down) and 50 mm on rudder this plane is a blast to fly, sort of a pattern trainer I guess, because it flys turns and spins straight as an arrow. I do 8-point and slow rolls, Cuban eights, inverted spins, Immelman turns, knife edge, avalanche, box and hexagons, snap rolls, hammerhead stalls, one guy at the field said I wouldn't be doing that long because the plane was not made to withstand the stress, he may be right. I only have the build sheet and it does not say who made it, only Explorer-40. It did tell me how to put the wing between two chairs with a fifty pound weight in the center to test spar strength before flight, and I beefed it up some with 3/8 inch oak round stock. Anyhow, don't get me started! As for my running hot issue, the muffler was hitting the fuselage a little so I clearance it, put it back together and she is purring at 12,500 RPM within 300 to 320 degrees at WOT pointing the lazer directly at the glow plug, transitioning nicely basically running as I would expect. Guess I ran across and inadvertantly corrected a sealing problem, guess I will try an A-3 plug, 10X6 prop and 15% Omega sometime to see if I can get into the 14,400 RPM range, but for now I am happy with 12,500 RPM on the ground and probly 1500 RPM more in the air would you say? What would you say?
