Got the front wire brace in place. Hope it will hold up, as it is the structural integrity of the front cabin top. Has anyone got any advice? I plan on using a lock nut on it and glue! I also have a tow hook I'd like to use on this Cub, but I would have to leave the top fin off. I had to heat up the V-brace wire to make it fit right, as one side was a tad longer than the other. I've got the engine standoff bolts running through the back of the blind nuts for now. I may cut the heads off, or just keep it like it is.
I always thought the V-Brace was designed to eliminate side to side (roll) movement and was a seaplane add-on for many planes. . . I'll have to revisit the Cub design... maybe I'm just thinking of non-cub's. I'd think the wing struts are the main source of structural integrity for most planes - surprised there isn't more beefy cabin window post structure. Every bit helps!
I've seen a full scale Cessna 206 with a crack in the passenger door jam and the whole entire window post and V-Brace was loose causing scary excessive motion. Obviously this model has some unique bends in the V-Brace design to help a bit with hold down force.
Since I'm talking about things I've seen... I know a guy who put wings on a J-3 (decades ago) and left #2 pencils in the aft wing spar bolt holes and flew around....once discovered and the pencils were removed undamaged! Turns out that rear spar is mostly along for the ride.
