Paul,
Three inches per panel, giving it a span of 59" Yes I am planning several mods.
The original Sportmaster had a tricycle landing gear, Lazer-works offers a tail dragger option that includes ribs with the landing gear notch forward of the main spar. Mine will be a taildragger but I decided to mount my landing gear on the fuselage just forward of the wing, so I ordered my kit with no notches in the ribs at all. Oh, and by the way , the wings will be bolt on.
For power, I'm going to use my trusty OS Surpass .91 FS. I'm still thinking about going with a radial cowl like the GP Aeromaster. Kinda give it that Gee Bee look, we'll see. Other mods, obviously dual aileron servos instead of the old bellcrank linkage, I might relocate the rudder and elevator servos to the tail depending on how it balances with the .91 My goal is to keep her as lightweight as possible. I will start on the second wing panel this weekend, probably won't post anymore pics until the wings are joined.

Thanks for watching!
