Ultrasport 40 "Plum Crazy" Electric Conversion
Purchased this glow Ultrasport 40 from a club member with the intention of converting it to electric.
It appears to be constructed correctly, and the price of $60 wasn't too bad. Currently it weights 3.6 lb.
I don't think the wing will need any modification.
Most of the work will be on the fuselage. Right now, I am thinking of cutting off the nose back to the firewall, and
making a motor extension box out of 1/4" plywood. Probably cut a hatch in the bottom for battery access.
I see Fiberglass Specialty's makes a cowl, but I am not willing to spend the money on that option right now.
I am going to have to find some Plum Monokote. It appears to be discontinued.

The dirty deed is done !
The deed is done. Sawed off the epoxy-soaked front end and sanded it smooth.
Cut a battery hatch in the bottom. I would have preferred to load the battery.
from the top, but that didn't seem to be an option.
he point here is just to make the plane fly. I will worry about looks later.
