Kit: SR Batteries (1:4)
This 1/4-scale model spans 100 inches and was built from the SR Batteries kit,
essentially out of the box. Power is a Model Motor AXI 4130/20 brushless
outrunner electric motor and an SR Batteries 24-cell 3000mAh battery pack. All
up weight is 17 pounds, 3 ounces. Flight times average 8-9 minutes. I have
also flown it with a Zenoah G-26 gas engine. Power is essentially identical;
the gas system only adds noise and duration.
The model has some significant deviations from scale, hinged ailerons and
elevator instead of wing warping and a full flying stab the most obvious.
Regardless, it is a very practical model for general sport flying, and can be
rigged for flying in just a few minutes. It is often my model of choice for
lunch time flying sessions.
The kit is exceptionally well designed, and goes together very quickly. I had
the airframe on the gear and ready to cover in less than 40 hours. Total
construction time was under 100 hours, including radio setup, installation of
both electric and gas power systems, covering and markings. All markings were
hand painted with Nelson Hobby Specialties polyurethane paints, and very
slight weathering was applied with MinWax stain.
