The
PA-18 Super Cub was a big step up from the good old J3 Cub. Not only
did it gain a much more powerful, 150Bhp engine there was also the
addition of electrical flaps. All at the front of the market back in
1949. many survive today doing sterling work as glider tugs.
The
Black Horse Super Cub is a big model at 3.56m span (nearly 12 feet!) yet
she manages to sneak under the 20Kg weight limit and avoid the UK large
model rules. This was achived by careful design and attention to detail
during construction.
Good detail is provided, but has been
simplified a little to keep under the weight limit. The size and wing
loading means very docile flight characteristics and those flaps bring
her down to ridiculously low speeds for operation out of amazingly small
fields. No need for a full size airfield! This is by no means an
aerobatic model and the flight envelope mirrors the full size.
Construction
is the conventional balsa/ply/hardwood used in all Black Horse models
and then covered in a classic scheme using Oracover. The cowl is of
course GRP and then painted.
Although a big model, she dismantles into reasonable sections for transport.
You will need a good 120cc engine and need to be conscious of the weight when selecting it.
