Inspite of the notion that the Guillows Corsair doesn't fly, I'm attempting to build it for electric RC flight as well. I'm using almost all Guillows balsa and I am modifying very little. The changes I have made are minor reinforcements, and a main spar in the wing. I've got the standard 4ch set up going in. (no flaps, no retracts) I plan on using the GWS pico servos(6.5g) because they are a little lighter than the HS-55's(7.8g) and can handle adequate voltage beter than some of the lighter servos (CS-5.4, 5.6g). I'm covering with "Ultracote" (as suggested by LHS) because it's relatively light, and still strong. The disclaimer is that you don't heat it up supertight because it will crush your wing. I'm also planning on using a LiPo battery pack, and I haven't decided on a motor yet, because I don't have a total weight. For those of you who have the model there are 3 different designs for the tail surfaces. 1) The fixed tail surface, that has an airfoil design. 2) The Scale display design, that has an airfoil and moveable parts. 3) The U control design, made up of 3/32 sheet of balsa with moveable parts. I chose option #3 due to it's light weight (although I was have a grand time assembling #2). After reading several reviews, tail weight is very important. As I stated earlier, I have ailerons, and the gull wing design poses some difficulty with installing torque rods to allow movement. I saw another post where a guy used cable (heavy) and a bellcrank to control the ailerons. I'm going to do this but tweak it a bit and use piano wire between the servo and bell crank to save on weight. For the landing gear I replaced the white nylon piece with 1/8" plywood for needed support, and I'll just attach my piano wire struts right to the plywood. If anywone is interested I'll attach pictures in the future.
