RE: SM F9F Cougar build
Nice video Alex..
I just finished one up a couple months ago.
Skymaster might want to put a little more fiberglass on the seam lines as i had cracks along the side of the fuse and top/bottom of the nose cone. Looks great when it leaves the factory but by the time we receive it there is damage caused by shipping.
Also when your assembling the mid flaps, Do not use the hinges to mount the servo control horns to. There is no mechanical advantage at all, Flap flops around allot.. I recommend to Flip the servo over so the servo arm is at the top side of the model and install a horn in the middle of the flap. This worked great and still had over 3.5" of travel in the flap.
Just a suggestion.
