I believe I read about a pylon powered ULF (maybe the one pictured?) that had a hard time taking off and the pylon ripped off and tipped forward and the prop sliced the guy's foot.  I recall a comment on the article that if had been a tractor instead of a pusher it would've been a lot worse.

But then I could be wrong and it wasn't even a ULF, but I think it was.

I've been curious by inside the cockpit photos that show up to the nose what appears to be a good size chunk of lead in the nose for balance.  First, if that is the case, seems like the nose should be lengthened a bit and move the pilot forward a bit to save the weight, but two, if it is lead, it could be a motor instead.  Maybe electric motor with folding prop.

If so, how was it done?  I would really like to go the electric motor route if possible, but would consider a gas engine too.
