On December 17, 1903,
Orville and Wilbur Wright accomplished the first
sustained, manned flight of a powered,
heavier-than-aircraft. Arguably the Wright Flyer holds the most
important place in the history of aviation, and it's
fitting that Great Planes would produce a first class
R/C replica of the Wright Flyer on the 100th anniversary
of its legendary flight. I also believe it is fitting
that it is a park flyer, suited to slow flight on
miniature grass fields in the backyards around the
world.
Great Planes has done a
great job capturing the essence of the nostalgia evoked
by the sight of this plane. With excellent detail and a
great stand-off scale look, it also offers something the
original didn't have....great flying characteristics.

| Kit Contents
and Manual
Great Planes
claims a 2 hour assembly time for this kit. I was highly
skeptical of this number since manufacturer's claims typically
are highly exaggerated. Let's find out how realistic their
claim is.
Instead of doing a blow-by-blow
of the assembly, since that's what the manual is for,
and it does an excellent job, I'll try to highlight any
difficult spots, or areas you should watch out for. To
be honest there weren't many steps that need clarification.
The manual is well laid out, with excellent detail and
plenty of pictures. My one nit on the manual is that the
pictures aren't as clear as they could be. This is due
to the quality of the page duplication and not the image
quality. I would like to see a bit higher quality in the
copying process so it would be easier to see details.
Other than that, the manual is great. A small addendum
came with the manual outlining a few errors in the original
manual, and a couple of changes in the assembly process.
This shows Great Planes great attention to detail, and
their constant efforts to make their kits better. They
are one manufacturer that doesn't put out a kit and forget
about it.
Kudos to Great Planes!
As you can see in the center
picture below, the kit comes very well packaged, and very
complete; it even comes with the appropriate Nimh battery,
speed controller and switch. Very nice! The package even
came with a nice little profile foam pilot that isn't
even mentioned in the instructions. You can see it in
the lower left hand corner of the center picture below.
The only items that you need to complete the kit are a
couple of micro servos, a micro receiver, a battery charger....and
of course at least a 3 channel transmitter. One extra
item I needed that was not documented, was a mini connector
to extend the battery lead. I'll explain below during
the battery installation why this was necessary.
The "fuselage"
is made out of a pre-assembled plastic framework. It appeared
fragile to me, and it did turn out to be a bit fragile
for my tastes, but I have to admit it was much stronger
than I expected. I would have preferred to have seen the
framework made out of a more flexible plastic, but this
is really my only complaint about the quality of the kit
contents. The foam wings are fairly thin, but they are
pretty tough too. Since they are foam, it is easy to make
field repairs with tape or 5 minute epoxy.

Installing
the Wings
This is a pretty straightforward process, but there are
a couple things to watch out for. The addendum has a note
about the wing assembly and it is important. In the main
manual they mention when you insert the wings that you need
to center them using the marks on the wings.....the problem
is there aren't any marks on the wings, so you need to make
marks on the center lines of both wings BEFORE sliding them
into the frame. This is a very simple task, but you must remember
to do it (guess who didn't read the addendum. :-( ).
The holes for all the components
in the wings are precut and drilled (you can see this
in the picture on the left below), except the servo holes
(these will very in size depending on the servos you use).
This saves a ton of time locating and drilling the holes.
They're very accurately done and really make the wing
assembly easy. I was starting to think maybe there was
something to their two hour claim.
The motors are already wired
and pre-mounted on the wings. Another great time-saver,
but make sure and read the flight section carefully where
I tell about a couple of problems I had with the pre-assembly.
Two more things about the
wings. Make sure and heed Great Planes advise on not over
tightening the aileron control horns. Once you over crush
the foam wing, there's no un-crushing it. Also,
they tell you to be careful sliding the wings into the
frame, and I will re-emphasize that. Take your time and
go slowly. Don't force them in the slots and they will
go in without any damage.
The wing struts are a bit
tricky to install, but if you follow the instructions
carefully you won't have any problem.
There are two strings that
act as guy wires to strengthen the wing and they are precut
and already have little loops on the ends. Again, excellent
attention to detail and a great time savings for the builder.
This is another place to make sure and read the addendum.
The manual describes two different length strings, but
they have been changed to all being the same length, so
don't get confused trying to figure out why both the strings
are the same length.
Installing the top wing is
another process that you need to take your time on. As
mentioned above, go about this slowly and don't force
the wing. It's a bit tricky getting the top wing in with
all the struts sticking up, but it's not that bad if you
take your time.

Servo Installation
Servo installation is fairly straightforward, but may require
a little extra fitting if you use servos other than the
recommended ones....which I did. If you're using the recommended
servos they should just slip right in (after cutting the
required cutouts in the wings). There are a couple of issues
here. First there is another note in the addendum that covers
one of the issues. The wire connecting the aileron servo
to the aileron bell crank has a "V" bend in the
middle of it. This is used to make fine adjustments to the
pushrod length to get both ailerons to line up correctly
at neutral. They were both fairly close to exactly the right
length to start with and required only minimal tweaking
to get the ailerons just right. It is a bit of a pain to
get the "V" compressed or extended. If you're
compressing the "V" (shortening the rod) I used
a pair of small vise grips and it worked pretty well, but
required some patience to get it just right. If you're stretching
the "V" (lengthening the rod), it's a fairly straight
forward task to spread it a bit, but then you will need
to bend the rod on each side of the "V" so the
rod is straight again. This probably sounds harder than
it is, but is necessary to get the ailerons lined up correctly,
so don't skip this step.
Next, on the elevator (canard) servo pushrod, it isn't
obvious from the pictures which side of the frame near
the servo the rod goes on. Hopefully the pictures I've
enclosed below will make it more obvious for you. Again,
with this step read the addendum for detailed instructions
on installing the clip that supports the pushrod.
Thanks again to all the pre-bent and pre-built pushrods,
it was very quick and easy to install both the servos
and linkage.

Assembly
Follow the same advise I
gave on assembling the wings for the canard. Be very careful
and don't force the canards into their slots. Assembling
the canards and elevator control rod is very straightforward.
While assembling them I was not very happy with the way
in which the elevator worked. Because of the attachment
method, the elevators didn't appear to work in unison
while manually working the pushrod, but as I'll report
later it didn't seem to affect flight performance in the
least, so if you notice the same thing, don't worry about,
it works.
Although the addendum says
that the rudders are now already glued in place, mine
were not, but I think it's possible that they were knocked
off during shipping, though they were not damaged. It
was a simple matter to glue them back on as per the manuals
original instructions.

Radio Installation
Talk about a simple radio installation! If you use
the Great Planes Electrifly 4 channel receiver, like I did,
it just slips neatly into the little box already installed
on the wing (picture on left below). Next you cable tie
on the included speed controller and switch as in the picture
on the right below. You can now plug the servos into
the receiver, motors to the speed control, and speed control
into the receiver and you're done except for the battery
installation. |

Battery Installation and Balance
I'm making this a separate section because it is extra
critical with this model that you get the balance correct
to ensure the successful flight of this model. Also,
I ran into my first real problem assembling the model
while installing the battery. The supplied battery and
switch did not have long enough wires to reach each other.
I ended up lengthening the battery wire to reach the wire
from the switch (see the picture on the left below). Instead
of splicing a length of wire onto the existing battery
lead, and using the same connector that came on the battery,
I chose to use another connector that I already had so
there would be only one splice on the battery lead. You
can see this in the picture on the left below. It did
not turn out to be a problem with the different connectors
as they still plugged in together, though the lock on
the original connector would not work with the new connector.
I did not see this as a problem because it is such a low
stress, low vibration, installation. I did make sure that
the wires on both sides of the connectors were held securely
with cable ties.
Ok, so the instructions intend for the battery to be mounted
parallel on the canard battery mount location, and if
you run into balance problems, the instructions suggest
adding weight where necessary to balance. Personally,
on small planes like this, I try to avoid adding weight
if at all possible, so I looked for another solution to
achieve correct balance without adding any weight. The
model did not balance correctly with the battery mounted
in the suggested position, so I ended up turning the battery
perpendicular to the canard and then I was able to move
it back and forth to achieve the correct balance without
adding any weight. I secured the battery to the canard
with a small Velcro wrap which allows the battery to be
easily moved back and forth for balance, but holds it
securely in place when tightened.
The instructions are excellent for the balancing procedure
so just make sure and follow them, though I would suggest
using my method of mounting the battery to eliminate the
need to add extra weight to balance.
The radio antenna installation can also be seen in the
pictures below. You'll see that the antenna has been wrapped
around the fuse structure to use up some length while
not compromising reception range. You'll also notice that
the antenna is run forward on this model, not to the rear,
because of the canard design. The excess, which isn't
much, dangles off the front of the plane.

Control Setup and Flight Preparation
The control setup is very straight forward, but there is
one really big caveat below, so please read this section.
If you followed the instructions for installing the controls
all you should need to do is set the control throws to the
recommended values, and trim the controls so they are centered.
Now comes a REALLY IMPORTANT step. Make sure the control
surfaces are moving in the correct direction. The ailerons
are standard in the directions they have to move, but remember
this is a canard design so the elevator moves in the opposite
direction of conventional model designs. If you set the
elevators up backwards you are sure to crash on the first
flight, so take your time, think it through, and make sure
you have it right.
What you need to look for is when you give back stick
(typically up elevator in a conventional design) the elevator
should move DOWN (picture on the left below). This will
make the plane's nose rise to make it climb. When the
elevator stick is moved forward the elevator should move
UP (picture in the center below). This will make the plane
nose down and dive. If you've never setup up a canard
and you're used to conventionally designed planes, this
will seem very wrong, but it isn't. Make sure your
instincts don't win out, because your first flight will
be even shorter than the Wright Brothers if you don't
get this right.
Now we get to my second problem, which reared its ugly
head during my second flight. The problem is Great
Planes' quality control, but it is a minor issue, and
is easily avoided, if you address it before your first
flight. Unfortunately I didn't follow my typical procedure
of not trusting ARFs and their pre-installed components
and I didn't check that everything was tight before my
first flight. Please don't make the error I did; make
sure and check all pre-installed components to make sure
everything is properly tightened. There actually is very
little to check, but I could have avoided a crash if I
had been a bit more diligent. Specifically, you need to
check that the nuts that hold the propellers on are tight,
and also that the screws that hold the motors on are tight.
Both came loose after a couple of flights.
Now, something that isn't mentioned in the manual is that
the motors are actually mounted with a slot in the rear
mount which allows the motors to be tilted so you can
adjust their thrust angle (picture on the right below).
A very nice design touch. Since this is not mentioned
in the manual, the correct thrust angle is not documented,
so for most people I would just leave them where they
come set from the factory, but make sure the screws are
tight and make a note of where the stock setting is in
case you have to take them apart at some point and need
to get them back to their original position.
OK, we're done, so how long did it take? How exaggerated
were the claims of 2 hours start to finish? Surprise,
surprise, they weren't. It took me one hour and fifty
minutes, including the mod to the battery wire. I was
very impressed. I don't ever think that I've ever
built a kit or ARF where I've even come close to the manufacturer's
claimed build time. I am a pretty experienced builder,
so a newbie is probably going to take a bit longer, but
I wouldn't think by more than a 1/2 hour to an hour, so
you're still looking at a max of 3 hours, which is really
not bad at all.
It looks like we're ready to go, so it's time to charge
up the battery pack and head out to the backyard.

Since I wanted to try and duplicate the
Wright Bros flight I spent a bit of time setting up a
ramp for the Wright Flyer to take off from.....but
unfortunately I wasn't too successful. There was just
too much friction. I could get it to move (check
out the video), but it wouldn't get up enough speed to
take off from the ramp. I could have built a dolly with
wheels to drop away on takeoff, but that wouldn't
have been very realistic, so I gave up on the idea and
made all my launches as intended by tossing the Flyer
out of my hand.
First Takeoff
For the first flight I double and triple checked
the control movements to make sure everything was moving
in the right direction. I then did a motor run-up to
make sure it was running at full power. With the wind
down around 5 MPH and all systems appearing to be a go,
I gave the Wright Flyer a toss into the wind and off it
went. A very uneventful first launch. It flew away
nicely with a very gentle toss and immediately started
to climb.
Flying Around
I
only had to add a tiny bit of down trim and a little
aileron trim. The Flyer was much more stable than I had
expected. I was flying on high rates from the beginning,
but the roll rate is pretty fast, and the elevator a bit
sensitive, so I'd recommend if you're new, or fairly new
to R/C planes, that you fly your first flights on low
rates. It is very docile on low rates leaving no doubt
in my mind that this could be used as a trainer for
someone new to R/C. I tried some gentle turns in
both directions and it was very easy to maintain a
constant bank. I'm sure if I was flying in higher wind
it would have bounced around a bit, but the little bit
of wind I was flying in, didn't have much affect on its
stability. I then tried some climbs to see how well it
would gain altitude and it isn't bad at all. As long as
you don't try to force it to climb and are patient
making small banked turns as you climb, it will just
keep going up and up at a decent clip.
Slow Speed Flight
For obvious reasons I always I like to check out
a new plane's slow flight characteristics as quickly as
possible during its first flight.....so, I slowed the
Flyer down to see just how well it behaved at slow
speed. Again, the plane was very stable, in fact, it was
amazing. Thanks to the canard, this plane is virtually
impossible to stall. As you slow down the canard stalls
before the main wings, making the canard drop as it
stalls picking up flying speed on its own, so the main
wings are nearly impossible to get into a stalled
condition. I'm sure it is possible, but I couldn't do
it. Since you can't stall the main wing, you also
don't have to worry about tip stalls, which is often the
death of a new flyer's first plane(s). Well you don't
have to worry about it with this one. Since it was so
well behaved I went ahead and brought it in to land on
the grass, and as expected it touched down at a crawl
and stopped in a foot or two. A very friendly flying
plane.
Aerobatics
What a silly heading for this type of plane. :-) Of
course this plane was never intended to fly any real
aerobatics, full-size, or model. The full-size could
barely get off the ground, but believe it or not the
model will do a couple of common aerobatic maneuvers,
but you do have to work at it a bit. You'll want some
altitude, but if you pick up some speed in a shallow
dive and have high rates on, you can do a loop or roll.
The rolls are actually pretty decent looking, but the
loops are a bit funny. If you had some more power this
plane could perform a very nice looking loop, but I was
impressed that it would do it at all.
Second and Third Flight
As
I alluded to during the construction I had a couple of
problems with the plane due to not double-checking the
tightness of pre-installed components before flying. Bad
me. On the second flight I was about 6 feet off the
ground...luckily I was flying around low....and the
Flyer all of a sudden nosed over and dove right into the
ground. There was only minor damage with a cracked
canard and a broken brace on the framework. What had
happened is the left rear engine mounting screw, the one
that adjusts the thrust angle of the motor, had come out
and the motor had moved to full down incidence causing
it to dive. It only took me a few minutes to fix
it up as good as new and prepare for my second flight.
Preparing for flight I ran the motors to full throttle
and one of the propellers went flying off. Again I had
forgotten to check the tightness of the pre-installed
hardware. You'd think I would have taken the time after
the first failure to check the rest of the plane out,
but I didn't. I would suggest you don't make the same
"novice" mistake. :-(
General
Flight times were around 7 minutes. It would be very
tempting to put a Lithium Poly battery in the Flyer to
extend the flight times and to lower the weight a bit at
the same time. You could easily double your flight time
with the LiPo.

Final Thoughts
All I can say is that Great Planes did a
phenomenal job making an inherently terrible flying
full-size plane, into a very stable and forgiving flying
model. If you want a really unique, great scale looking,
fun plane to putt around the backyard, or even learn to
fly on, this model would be an excellent choice.
As I mentioned I would
have liked to have seen the framework made out of a bit
more flexible (durable) plastic, but it is easily
repaired and although the plastic seems brittle, it does
have some flexibility and I proved that it can withstand
a pretty hard impact without serious damage.
If you hadn't already
guessed, I highly recommend the Wright Flyer. |
