A-10
The A-10 you are referring to is from RCM, a .40-.46 size pusher, all wood, designed by Mike Pastro, who also designed several other planes, including a F-18 pusher for RCM. You can call RCM Plans Service and they will know they number or you can go to their website and look through their plans catalog, I think it is under scale subjects. The fiberglass nacelles and canopy are available from Bob Holman Plans in San Bernidino, CA.
Good luck, it is an easily built airplane, and looks good when it is done.
