Q: What kind of a nut plops an unfinished engine into an unfinished prototype?
A: The kind that only has unfinished renderings and is making up the design details as he goes.
I guess I can glue this block of wood here for a 700HP engine mount and file it to fit, then I'll slap a little fiberglass on it just to be sure it is really strong. And I'll drill a hole through a hockey puck to bolt in between and absorb all the vibration. I'd better put a little aluminum foil on there for a firewall. Damn! I bet I can make my electrical system out of these old Christmas lights, and form my Plexiglas windshield with my girlfriends curling iron. Woohooo!
Actually, wood is a fine composite material. The 787 is largely composite. Why not the car? I like it. Also, check out the GP-4 aircraft. Or, Mr. ME-262, the English Mosquito :0)
