The
battery fits in the right side compartment. The speed control is a
Thunderbird 54 amp unit. It is restrained with a tie wrap on the
wires. All of the motor
mount parts are
notched and keyed for easy and accurate alignment. The downthrust
seems to be appropriate. The motor is a 480 size Suppo BL 2814-8.

The buck for forming
the cowl. I used two layers of medium weight cloth and
Isophthalic resin to make the cowl. You can see the cross grain
templates that are embedded
in the buck.
These
are on the plan on a separate 11 X 17 sheet. Sand down to the
templates and fair the balsa
blocking to them.
There
is a layer of glass cloth and resin on the buck. I
split the cowl down the middle of the bottom to get it off the buck.
