Maybe make a cockpit with cool cockpit view plus ejection capabilities?

When I'm stumped sometimes I download a random plane and mod it. Find it quite satisfying to make something look better/ fly better. Or you could take a plane like hypnotoads - strip the wings off and use the chassis - you will be amazed how quickly different something turns out. Whatever you do - try something you haven't. Yes the folding planes are insanely cool but have a look at other formats. Keep it up I love your planes. All the best.

Ahhhh nooooooo. Mate you can't stop. Also, thus was really cool! Had a nice little fly around in this just now. Was bob on! :) great work as always. Ok well ideas. Given your amazing style and ability I think you could be ambitious! If I am ever out of ideas. I make shapes, so 8l ill add a very long line of blocks behind the cockpit, and then add structural wings to one side. Then mirror the plane when I'm happy with whatever shape I created. Once That's done I'll re mirror that shape and attach it somewhere else, or rotate it and re attach it. If that's not enough then I would look at modern super cars, or even some plane concepts on google images. Failing that go back to your favorate movies, I would bet there would be something in one of them to inspire you somewhere.
