airfoil question for my delta wing

made a delta wing, epoxied together 3 ieces of 1/2" thick x 4"wide foam and epoxied 1/16" balsa for the flatbottom`s survival on landing and to add some strength.
I made the front ortion of the airfoil just fine,but my breadknife didn`t deal with the epoxy ridges very well.
after the monokote was on,I noticed that the iron finished off my terrible attempt at an airfoil and everything rearward of the apex of the airfoil was concave,like the shae of an undercambered wing but of top.

How terrible is this going to fly?

I keep thinking it will want to do like frontflips lol/nosedives

Sounds like you have a reflex airfoil. It may be just the thing for a delta. Fly it and see.

Thats my lan for tomorrow,should be really interesting to see if it WILL fly or just be dragged through the sky by the babe bee 049 on the nose lol

Next is one with a decent airfoil if I can manage that( lol) and then scale one down to 020 size, then one for my throttled COX TD 010 if possible
