Hi Bill,

I'm relieved.  I won't have to mortgage the house until the technology
advances enough to reduces the weight by a factor of 5. Currently it
looks like I would need about 1400 lbs of batteries.  Get it down to
280 lbs and allow 100 lbs for the electric motor and my W&B will work
out about right. :)

I'm looking forward to seeing what you come up with for the aircraft
batteries.

Bob or Bill
I would have thought a 130hp DC Motor  would weigh more than 100lbs.
Any rule of thumb on weight of motor to power output ?- I guess there's a
lot of copper windings per HP!?
