Great looking jet!
When you get to test flying it, protect the nose with something like
a sponge or scrap foam. After a couple of dives testing out my foam
jet the nose ended up smooshed like an accordion.

Got the yellow winged plane flying pretty good now. Adding weight to
the nose solved the nose diving problem. Odd as that sounds, the weight
must be returing the lift back to under the wing.
Clipped the rudders and bent them in- tail now looks like a Star Wars TIE
fighter, but the plane flies and climbs nice.
