RE: MR Aerodesign 1/4 Scale Mudry CAP 10b Review / Build
Day 12...
Fin (vertical stab.), and Ailerons
Fin:
This is made in the same way as the tailplane was. Using 1/4" x 1" stock trailing edge as a guide, and the tabs on the ribs facing down. Attach all the ribs to the traing edge.
Cut some 3/32 x 1/2" play spars from scrap (they are not provided) and glue the top spar in place making sure all the tabs are flat on the board.
Add the 3/32" balsa leading edge and sand down to the rib edges.
Add the top sheeting then sand it flush with the the leading
Remove form plan and turn upside down. Now you can remove the tabs and sand the trailing and leading edge down to the rib level.
Add the sheer webbing and hinge blocks as needed.
Add the sheeting and leading edge 1/4" stock than sand the whole thing to shape...
Hold the finished structure up to the fin and make sure the tops are even. Add the Rudder tip block to the rudder and sand to match the contours of the fin tip.
