of 20. 5 pounds. With electric power it
can go from the box to ready to fly in
10 to 12 hours.
Assembling the aircraft at the field is
surprisingly simple for a model of this
size. No tools are needed. The wing
struts are held in with a clip and the
wing halves are held to the fuselage with
a thumb-tightened nylon bolt.
Not knowing how effective the flaps
would be, I chose to not to use them
during the first takeoff. Even without
flaps and using only half power, the
Beaver quickly accelerated down the
runway and was off the ground in
roughly 200 feet.
When the Beaver was up to a safe
altitude, I backed off the throttle and
found it would easily cruise around
between one-third and half throttle
With the trim passes completed, I
decided to try out the flaps. As you
might expect with a STOL-type design,
Raising the flaps cleans up the
airframe and allows it to become
aerobatic. Although the full-scale Beaver
doesn’t do loops and rolls, the Hangar 9
Beaver performs them with ease.
Rolls are slightly slow because of its
large 110-inch wingspan. It makes a
good barnstormer-type airplane with
snaps, Hammerheads, and even some
inverted flight. It looks odd doing some
of those maneuvers, but it is fun.
When it comes time to land, simply
drop the flaps and glide it home. It
might require a touch of power to
maintain forward speed, but it’s a
pussycat and could make a good trainer.
Since completing the Beaver, I’ve
put nearly two dozen flights on it
with no problems. I find it relaxing to
fly late in evening with the landing
lights shining brightly. Because of its
size, the wind barely affects it.
The electric power system is more
than the Beaver needs. You can cruise
at no more than half throttle for more
than 25 minutes on a single battery, but
it is nice to have extra power when you

The wealth of scalelike details on the
Hangar 9 Beaver makes it difficult to tell if
it’s a model or its full-scale counterpart.
