RE: World Models P-51 Mustang G.S. ( S1 - Ridge Runner )
I have the world GS miss america version which is an early version built without flaps. this plane flies very well and has no tendency to snap at low speeds. I changed the retracts to Spring Air 400 size retracts which have been flawless. I also reinforced the wing bolt area and changed to 1/4-20 wing bolts. right now I have a super tiger 2300 in it and this engine flies this plane very well, so if you are thinking of a glow engine this or maybe the os 160 would be good choices.
sorry I didn't have a digital camera when assembling mine.
