I am speaking of the earlier models, since it was probable ten years when I purchased my CMP P-40 40 size with 54 " wings ( from recent photos from Nitro, the thing hasn't changed any, except the color), then it was offered in a plain silver paint and covering. The aileron servo consisted of the original single one in the middle of the wing, I do not know if that configuration has been changed in the newer versions. I painted mine Camo (Army) green on the upper surfaces and added my own guns, pilot, dash board, and other details. As someone said in a previous letter, keep it Light, this aircraft is all ready heavy for its size...that is why mine was so hard to land, because of the wing loading, its loaded up. Fast speed is the only way to land this thing, so good luck! And the landing blocks do need attention as earlier posted, due to the fast and furious landings ( I luckily made good landings, so I never busted out the blocks, but I foreseen that it would of could of). Mine was a good flyer, but it was quick and snappy, I really had to pay a lot of attention when flying, or she would get away from ya, this is by no means for the average flyer. It is demanding and actually not a lot of fun to fly if you prefer a hands off flying aircraft. To sum it up, this aircraft is Fast & Furious as well as a Beauty if detailed out....
