Laser 3D
step 37
because I am a belgian guy, I fully understand the instruction book, and I will be happy to help you
first glue the 6*6 balsa reinforcements each fuselage side has 3 pieces of 6*6 balsa reinforcement one long on the top and bottom and a small one on the bottom betwwen wing and front fuselage. be careful and locate the position were the spars stop in the aft fuselage.
My above instructions assume that you have perfectly glued together the two ply pieces making each fuselage side (to do that use a straight stuff laying in your workshop to align them)
BE SURE TO BUILD A LEFT AND A RIGHT ASSEMBLY
about your ailerons, you will notice that there is a line on the plan drawn on the leading edges spars of ailerons, this line is the ref line showing you that you must sand the edges to a V shape
got it?
hope this help......
