• The included brushless power system gives
the Ryan a wide performance envelope.
• The overall quality, fit, and finish of the
airframe and covering are good.
• The bulk of the assembly can be completed
in 1-2 hours.
• A spare 10 x 6 propeller is included.
• The included rigging wires are lacking in
quantity and quality.
• No pilot figures included.
• The elevator pushrod binds because the
angle is too steep as it exits the fuselage.
AT A GLANCE ...
The rigging wires that came with the aircraft are elastic, but difficult to
install. I opted to instead use some black cording from a local craft store.
Durafly includes precut lengths of thin, black elastic cordlike
material, but the number of included pieces did not align with
the number required to make the model match the one shown
on the box’s artwork. Additionally, I found working with the
cording cumbersome and frustrating. I instead decided to use
some slightly thicker, non-elastic cording from a local craft shop.
My technique for installing it involved inserting the screw
into the model and driving it in until it was almost fully seated.
I then looped the cording around the screw and carefully
tightened the screw the rest of the way. A drop or two of
medium CA secured the cording to the screw.
Installing the rigging wires doubled the assembly time,
but omitting them would be tantamount to flying a biplane
with only one wing in place. The rigging wires are an integral
and iconic part of aircraft from this era and they enhance the
Durafly provides recommended control throws in the user
manual. The recommended CG is listed as 55mm behind the
wing’s LE. Although the recommended battery is a 3S 2,200
mAh pack, I prefer to keep my electric aircraft as light as
possible and decided to try to use a 3S 1,800 mAh LiPo.
I hit the recommended CG with no problem, although I
positioned the battery all the way forward in the provided space.
Some hook-and-loop material was required to hold it in place.
My Ryan’s all-up weight came in at 29 ounces ready to fly.
This is a few ounces lighter than the number in the Durafly
specifications, which was expected given my choice to use a
smaller battery pack. But lighter is always better when flying
Aircraft common to this era are often configured in such
a way that ground handling can be challenging. The main
landing gear on the Durafly Ryan recreates the narrow spacing
of the gear on the full-scale aircraft, although the tail moment
is slightly longer than other models of the era. I conducted a
