Default Convert a old r.c. wing to c.l.

Just want to run a feasibility and practicality question by you guys.<p class="MsoNormal">I have an old r.c. wing that I picked up a long time ago. It looks similar to a stick .40 wing. 50&rdquo; span and 10.5 &ldquo; chord, With the ailerons making up 1&rdquo; of the chord. It looks to be about an 18% thick symmetrical airfoil.</p><p class="MsoNormal">I am thinking of converting it to a c.l. with a OS. .25 bb r.c. for power.</p><p class="MsoNormal">I would cut the center out and rejoin to remove the dihedral. That removes 4&rdquo; of span. Should I also remove a rib bay each end to further reduce span and area?</p><p class="MsoNormal">Since the t.e. is already hinge should I add flaps? Does 1.5&rdquo; sound right?</p><p class="MsoNormal">So these changes would yield a 42&rdquo; span and a chord of 11&rdquo; for a total area of 462&rdquo; square&rdquo;.</p><p class="MsoNormal">A box fuse would be easy and fast to build. A stab of 100&rdquo; to 120&rdquo; square&rdquo; about 12 inches from the wing t.e.</p><p class="MsoNormal">Do these numbers seem right?</p><p class="MsoNormal">The idea is to finally put this wing to use and I need a fast build c.l. for my spare engine.</p><p class="MsoNormal">I want to fairly aerobatic, no need for competitive.</p><p class="MsoNormal">I don&rsquo;t have a bigger spare engine that I can use. So that sets the limits.</p>
