on October 26, 1931. The Royal Air Force took notice
and began using Tiger Moths for elementary pilot training.
By the end of World War II, de Havilland had delivered
more than 4,200 to the RAF. About 3,000 more were
built in Australia, Canada and New Zealand for Commonwealth

Tiger Moth arrives in a well packaged box with all of the components
wrapped and taped down. Once all of the items are removed from the box,
you immediately realize that there are only a few components and that
this build should not take more than a few enjoyable hours.

dual cockpit area complete with wind screens and instrument panels. The

to complete the assembly.
suggest that the bottom of the wings are reinforced with some fiber
tape if the Tiger Moth will be flow outdoors in windy conditions. As I
rarely find a good indoor arena to fly, I decided to perform this step
using some BiDi
tape. The slots for the landing
gear are then cut from
the bottom wing. A C.G. marking template is supplied on the last page
of the manual. This is cut out and then attached to the wing to

then glued on to the center cabane struts. The manual suggest that the
Tiger Moth be flipped on its back to check for alignment of the both
wings but again, I did not have to make any adjustment as the fit was
near perfect. The installation of the wings is the completed by gluing
on the outer cabane struts.
glued on, we move on to the tail section. The stab and the fin are
first prepared by removing the thin layer of skin from the Pro-Formance
foam. Make sure you do not apply too much pressure when test fitting
the horizontal stabilizer to the fin as the whole assembly can easily
crack under pressure. Before gluing on the parts, make sure you flex
the elevator and rudder a few times to make sure the hinge joints have
sufficient movement and that they are not too rigid. The fin can then
be glued on to the stab and the whole assembly glued on to the tail
section. Make sure you check first that the horizontal stabilizer is
parallel to the wings and if not trim off some excess foam from the
tail section to make it so.

glue on the control horns and attach them to the push rods using the
micro FasLink connectors.

steps required to complete the Tiger Moth assembly involve installing

simply slides in place and is then supported by the V shaped wooden
struts. The back of the struts do not actually make contact with
anything to absorb the flex from the landing gear.
held in place by 1.6x4mm wood screws which are very tiny and can easily
get lost if dropped. The manual recommends that you use a small drill
bit in the range of .040" to .052 to drill the screw location. As I did
not have such a small bit, I used the tip of a hobby knife to make
a tiny hole and insert the wood screws in their respective locations.
The 8x6 Slo-Fly propeller is then attached using the prop saver

weekend, I charged the collection of 300mAh batteries that I have
and headed out to the field hoping for calm weather. Luckily, the
flight of the Tiger Moth happened to land of a fairly calm day with
very little wind.
With a freshly charged battery, I set the timer to 5 minutes and
spooled up the motor. Facing the wind, I applied a little throttle and
within a few feet, with almost no rudder correction, the Tiger Moth was
airborne and climbing. I had to apply a little down elevator trim to
achieve straight and level flight.
The Tiger Moth is really a relaxed and easy to fly slow flyer as
advertised. Turns are easily achieved with rudder and elevator and the
lack of ailerons are not missed at all. While the Tiger Moth is not an
acrobatic aircraft, I was surprised at some of the maneuvers I could
perform including tight loops and stall turns.
It was a please to see the Tiger Moth perform nice and slow
coordinated turns and scale like passes over the runway. While
pulling into a big loop at full throttle, I had the misfortune
of having the prop saver fail and losing the prop. However,
I was able to complete the turn and land without any issues.
I later replaced the prop saver with a 3mm prop adapter and
found that the added weight of the prop adapter and spinner
also helped with the CG as well.
Later on in the afternoon, the winds picked up significantly and I flew
the Tiger Moth again in winds that were in the 10-15mph range and she
handled it quite well though it was getting thrown around a little and
landings were harder. Also, to fight against the wind, I had to fly at
close to full throttle settings which reduced the flight time from the
300mAh battery to around 2-3 minutes.
Tiger Moth delivers on what is advertised as a pleasurable and easy to
fly model. I enjoyed flying the Tiger Moth outdoors in low wind
conditions. As it does not require a lot of space to fly, I looked
forward to getting home from work when the wind was dying down and
putting in a flight or two right in front of my house.
found that the
prop saver can be a slight hassle as no matter what I did, I ended up
breaking the supplied O-rings even while it was just sitting in the
hangar. Either a toolbox full or spare O-rings is in order or you may
want to opt for the adapter from the start.
300mAh battery will provide a decent flight time if you are flying in
low wind condition as the throttle required to pull the airframe around
is only around a quarter stick. However as the wind picks up, the
flight time will be drastically reduced as you try to fight the wind
with more throttle. But to be fair, that is not what the Tiger Moth was
designed to do.
recommend the Tiger Moth if you have access to an indoor flying venue
or can wait out for the calm days and enjoy the relaxing fun that a
scale looking slo-flyer can deliver.
