Ok here it is.

I am building an old ZIA Models/Flight line F-106 delta dart. The wing has a 42" span made out of solid 1/4 sheet wood. No airfoil. The kit has 1/2 wide plywood strips that glue on the tip and a 1/4" tall strip that glues on top of the wing to make a chine/strake. I would like to put the wing strip on the bottom to look better but not sure if it was designed to help with producing lift if installed on the top of the wing or to just stiffen the wing. I know with this flat wing there is a very small AoA angle that will produce lift before it turns into a kite per say.

So build it as designed or will it matter if the 1/4" tall strip is on the bottom of the wing? For the wing tip what will help the most with lift? having a 1/4" above the wing tip or 1/4" below the wing? Should I go with a larger wing tip?
