   Working on it non stop on it and hope to be flying in a couple of
 months, this one is stretched two feet longer to make a four place
 and I have added five inches of head room just for you.
   Let me know if you have problems opening this photo and I will send
 it on my other computer as I have been having problems with this one.

Hey thanks on the head and leg room. As soon as you get it
flying I'll be up there for another ride. Total fun. I love
it. If we had more water down here I would have one.

Looking good Ken. Netscape could do nothing with it but Linux
xv saved the day. Here is the pic.

I still think you should mount the motor low and use
a two stage cog belt drive. The top pulley could be real
small and you would have a very streamlined pylon and a lower
CG.

   I have raised the wing 5 inches and left the prop in the same
location and dropped the dihedral from 7 to 5.8 degrees and I think
this will be the best compromise as I don't want the engine in the
hull for the fire danger witch I am very concerned about, I am also
making a sealed fire wall so that noting can get into the hull from
the engine.
  Also this plane will have the twin pack on it that I tested on the
old coot and the second engine would take up the rear seat.
