President’s Message
Hello Everyone,
The summer flying season is well underway. In May we had the Helicopter Fun Fly. It was a very nice
day for flying. Thanks to all who turned out for the event, and thanks to our volunteers and especially to
Dynamic Hobbies for donating the prizes.
Our next happening will be the Warbird event in July at Greenway Field. We will publish more
information as the date approaches. Hope to see you at the event.
As the summer progresses, we will call for people to come out and help with events and with work that
needs to be done on the flying fields. To all our dedicated volunteers, many thanks for all your efforts.
And as always, please obey all of the safety rules, keep your airplanes away from the No-Fly Zones,
and remember to keep your hands away from spinning propellers.
See you at the flying field,
Mike Toner

GENERAL ENQUIRIES
Greetings Fellow Aviators,
Well I think we can safely say that flying season is upon us once again. Your snow blowers and snow shovels
should by now be tucked away and your favorite planes in readiness for the flying season ahead!
For those who missed the our last meeting, we had a very interesting speaker from the Aviation Museum, Doug
Carswell, who brought some pictures and a wealth of information on the development of the HS-2L Flying Boat that
is on display at the museum.
By self acclimation, Doug is not a man of few words and unfortunately he ran out of time getting the
presentation completed before his available time ran out so hopefully he will be joining us again to complete his
talk. Thanks to Calvin and Dieter for helping out with the loan of the needed video projectors.

A couple of weeks ago, the club received an email from lady named Sue McLarty from out of town. She was
looking to get some help from us on behalf of her father F/L Don McLarty who is a WWII Veteran Fighter Pilot. He
flew Spitfires and Hurricanes in North Africa and ended up being a POW in Italy. She was hoping he could come to
our field to watch us fly and possibly even fly himself.
Upon speaking with her, I suggested getting him over to the Vintage Wings Museum to see the Spitfire and
Hawker Hurricane they have there and mentioned the possibility of maybe being able to get him up in one of the
vintage aircraft. Well, the timing couldn’t have been better because Michael Potter has been in the process of
dedicating aircraft to a few selected Veteran Pilots. By lucky coincidence, he had a Hawker Hurricane that was
ready for such.
To make a long story short, I had the honor of attending the dedication ceremony last Friday with Brent,
Ramona, Michael Potter and all of Don’s family. There was also a surprise visit from F/L Ray Sherk, his friend and
fellow aviator whom he escaped with from the POW camp. I am thrilled to say we are tentatively having Don
th
attend our club meeting June 7 to share some of his stories with us.
Please help show our support by attending. At the rate we are losing the hero’s that fought so bravely for us, it’s
an opportunity that shouldn’t be missed. Hopefully you can all attend.
On another note, the executive has been working very hard in an effort to increase our membership. I am happy
to say we have come up with a plan to help do so. In conjunction with Dynamic Hobbies, who are offering a
onetime 10% discount to any new members to the hobby who have joined our club as a Student. ORCC is also
offering 50% discount off their first years’ membership. Their MAAC must be paid in full either to us or directly to
MAAC. For further info, contact myself, Brent or Dieter.
Finally, we are adapting the same plan for current members as MAAC which is “SIGN THREE, FLY FOR FREE!” in
which case you would have your membership and your MAAC free so encourage your friends that have been
thinking of trying RC flying come out on one of our Wednesday Training Nights and try flying one of our club
sponsored trainers. For more info, contact our Chief Flight Instructor, Brent Norman who is listed under our Club
Executives in this newsletter or on the ORCC website.

Scott Stoops is a commercial pilot for United Airlines who flies a full-scale Sukhoi 26MX in IAC
competition for fun on his days off. His new book, The Pilot’s Guide to Mastering Radio Control Flight,
is available www.rcpilotguide.com. Here is some advice from him about flying in crosswinds that I thought you
may find useful,
Ramona.
As an airline pilot, I get to fly with pilots from every background imaginable--some are civilian trained like myself,
and others are military trained pilots who have flown heavy tankers, helicopters, and high performance fighters
in their previous lives. While all are excellent airmen, there is one maneuver that illustrates each pilot's
experience quite clearly--the crosswind landing. What is a relatively simple and common maneuver for civilian
and heavy drivers is actually something foreign to fighter and carrier based pilots. Fighter pilots simply land in a
Crab during crosswinds, and carrier pilots have the skipper turn their runway (the carrier) into the wind!
No crosswind landings for them at all! I find many RC pilots also lack the basic understanding of the reason for
crosswind landings and the techniques required to navigate their model safely when the wind is not down the
Runway. Crosswind landing, you say? I thought we were supposed to take-off and land into the wind. In a perfect
world, yes. However, it is not always possible to do so as some fields have only one runway, and it probably isn't
always into the wind. In this article, we will examine why a different technique is required for crosswind landings
and learn how to execute that technique perfectly every time.
THE CRAB -- NOT ONLY A CRUSTACEAN!
To understand why crosswind landings are different from calm wind landings, it's important to acknowledge the
difference in track over the ground while flying in a crosswind. All airplanes are affected by the speed and wind
direction of the air mass in which they are flying. In calm winds, you simply point the airplane in the direction you
want it to travel and it will fly a precise course over the ground.
If you were to do this in a crosswind, the model would drift slowly downwind. To fly a precise path over the
ground in a crosswind, you will need to crab into the wind so that a portion of your speed vector is being used to
counter the drift caused by the crosswind. Like the crab walking sideways over the sand (going a different
direction than his nose is pointing), we crab the aircraft by turning it slightly into the prevailing wind to allow a
precise flight path over the ground on the intended track. If the wind is from the left, then you will need to crab
the aircraft slightly to the left into the wind to counter the crosswind. Crabbing works extremely well when flying
a track over the ground in a crosswind. Why can't we do this same thing when landing in a crosswind? When
landing, as you know, it is critical to be aligned with the runway. If you were to allow the model to touch down in
a crab, it would contact the runway crooked, which is asking for significant directional control problems or a
Cartwheel. Conversely, if you point the model down the runway with the wings level in a crosswind, the model
will be drifting across the runway at touchdown, also asking for huge problems. The solution is found in the slip.
Right aileron and left rudder will give a slip to the right. Adjust the controls to maintain a straight flight path and
cancel crosswind drift. Be prepared to correct any pitch coupling.

For Laughs....
Remember it takes a college
degree to fly a plane but only
a high school diploma to fix
one:
June 1, 2011
THE SLIP
The slip is a manoeuvre that we will use to help prepare you for crosswind takeoffs and landings. In the most basic
sense, slipping flight is uncoordinated flight, with the rudder and ailerons deflected in opposite directions. You
probably have been told to use rudder with ailerons in the direction of the turn to maintain coordinated turns in
normal non–aerobatic flight. Now we are going to un-link the two controls for crosswind landings. With a fourchannel model, it is possible to yaw the aircraft one direction and roll in the opposite direction, causing any turning
vector to be nullified, i.e., the model continues flying straight ahead with reference to the ground, while actually
flying sideways through the moving air--this is known as a forward slip as the aircraft continues heading forward or
straight. Used in this manner, the slip is a very effective tool to increase drag if you are high during an approach. It
is very useful to practice slips at altitude prior to using them close to the ground or during landing. At altitude, slowly
apply rudder in one direction concurrently with aileron in the opposite direction to counter any heading change. You
most likely will notice an increase in rate of descent as well as a pitch change. Practice steering the heading with
the rudder while keeping the wings level with the ailerons. Another good exercise that directly applies to crosswind
landings is to practice keeping a constant heading while varying bank angle, and thus a varying path over the
ground.
After every flight, Qantas pilots fill
out a form, called a "gripe sheet,"
which tells mechanics about
problems with the aircraft. The
mechanics correct the problems;
document their repairs on the form
and then pilots review the gripe
sheets before the next flight.
Never let it be said that ground
crews lack a sense of humour!
Here are some actual maintenance
complaints submitted by Qantas'
pilots (marked with a P) and the
solutions recorded (marked with an
S) by maintenance engineers.
By the way, Qantas is the only
major airline that has never, ever,
had an accident.
P: Left inside main tire almost
needs replacement.
S: Almost replaced left inside
main tire.
P: Test flight OK, except autoland very rough.
S: Auto-land not installed on
this aircraft.
P: Something loose in cockpit.
S: Something tightened in
cockpit.
P: Dead bugs on windshield.
S: Live bugs on back-order.
Allow the model to crab into the wind until beginning to flare. Start the flare and add right rudder to align the fuselage
with the runway, and left aileron to counter any drift. Smoothly add full up and full left aileron after touchdown, and
adjust the rollout with rudder.
THE CROSSWIND LANDING
So how do we apply the forward slip to flying crosswind landings? During a crosswind landing, we use the rudder to
align the nose of the model down the runway and the ailerons to prevent drift upwind or downwind By using the
cross control inputs of a slip, we can simultaneously counter drift by redirecting part of the lift vector with a slight
bank into the wind, while maintaining alignment with the runway centerline directionally with the rudder. The model
will touchdown with one wing low on the upwind main tire and the tail wheel first. As the
model slows, the downwind tire will touch To help prepare your thumbs and brain for crosswind landings, I
recommend flying practice crosswind approaches--establish a crab initially and at approximately 20-30 feet,
transition into a slip. Use the rudder to align the model's heading with the runway centerline and the ailerons to
adjust the model's position laterally to remain over the runway.
As you approach the runway, execute a go-around. Fly a normal traffic pattern, practicing crabbing throughout the
pattern and repeat the approach. As you get comfortable flying the crosswind approach, take it a little lower each
time. One item to note: when flying slipping approaches, there is significantly more drag on the model while slipping,
so you will notice a higher than normal rate of descent. It may be necessary to fly the approach with a slight amount
of power to reduce the rate of descent. There is one last point to consider as you come down final. The wind is
usually stronger farther from the ground. This wind gradient means that you need to reduce your crosswind
corrections gradually as you descend.

P: Noise coming from under

S: Took hammer away from

THE FLARE
Now that you are comfortable flying slipping approaches, it is time to put it all together. I prefer to fly a crabbing
crosswind approach, transitioning to the slip relatively late in the approach. Flying airliners in the full-scale world, we
often wait to transition to the slip until slightly before or even during the flare for passenger comfort General Aviation
pilots usually set up their slip a lot earlier, often soon after turning final. Try both to find your preferred technique. As
the model crosses through the three to five-foot altitude range, slowly close the throttle and initiate the flare. Notice
that as the model decelerates in the flare, you need to increase the inputs. This increase in control input will continue
until and, in fact, beyond touchdown. If you are flying a tail wheel airplane, smoothly add full up elevator after the
model touches down and begins decelerating to pin the tail wheel and ensure good directional control during the
rollout. As in all landings, use the rudder to maintain directional control on the runway after touchdown. Because of
the crosswind, there will be a strong tendency for the upwind wing to lift during the flare and rollout, so be sure to
continue to hold the aileron input in to keep the upwind wing down. Common problems during crosswind takeoffs
and landings include inadequate aileron input to cancel the drift, inadequate rudder inputs to counter the
weathervaning, and a loss of directional control, especially when landing with a tail wheel model.
CONCLUSION
The crosswind landing takes practice to master. Fortunately, an airline job allows even the ex-Navy pilots plenty of
opportunity to practice the art of the crosswind landing! You may find it interesting to know that virtually all full-scale
aircraft, including both the Boeing 737 I fly at work and my Sukhoi 26; use the exact technique I outlined above. If
you have a PC flight simulator that will let you fly along behind your model, you can quickly get a feel for how much
cross controlling of the rudder and aileron is needed to maintain runway alignment In the RC world, many pilots see
crosswinds as a great reason to put their airplanes away. I can't count the number of times that I've seen otherwise
competent RC pilots grounded by light winds simply because they were blowing across the runway. I hope that the
next time you're at the field when a light crosswind comes up, you'll take the opportunity to practice your newfound
understanding and skills. A good crosswind landing is a thing of beauty that I appreciate every bit as much as a
round loop, clean slow roll, or perfect torque roll. Till next time, remember, perfect practice makes perfect.

For the Fathers…
A Father is a banker provided by
nature.
4 years: My Daddy can do
anything!
7 years: My Dad knows a lot…a
whole lot.
8 years: My Father does not
know quite everything.
12 years: Oh well, naturally
Father does not know that
either.
14 years: Oh, Father? He is
hopelessly old-fashioned.
21 years: Oh, that man-he is
out of date!
25 years: He knows a little bit
about it, but not much.
30 years: I must find out what
Dad thinks about it.
35 years: Before we decide, we
will get Dad's idea first.
50 years: What would Dad have
thought about that?
60 years: My Dad knew literally
everything!
65 years: I wish I could talk it
over with Dad once more.
There were eleven registered pilots flying helis of all sizes ranging from a micro-sized Blade
MCPx to 50/600 sized machines. And I can’t forget to mention the quad head gyrocopter that
actually flew. Out of all of the helis flown, only two were nitro.
The event turned a profit and we gained one new member that I look forward to seeing at the
field throughout the summer.

ORCC Meeting.
Note from the Editor
Hello Everyone,
Well, Summer is only a few weeks away if you can believe it! I hope that you get the opportunity to come
out really soon to get in on the action on the fields. Greenway is a beautiful new hangout spot that is
becoming more and more popular and we still have Drummond where every Wednesday night, you can
get some good advice from experienced instructors and meet new members learning to fly.
This popular hobby continues to bring people together to share their same interests. I encourage you all
to pack a comfortable chair, some munchies and drinks, a camera, sun block and a hat, perhaps your
favourite book or better yet…AIRPLANE, and head out to see what everyone is up to at the upcoming
events and on the ORCC fields. There are lots of big events coming up over the next few months that
should be quite enjoyable. I am always impressed with the numerous dedicated members from all over
that get together for these shared activities. What a better way to get outside and spend some time just
hanging out and learning from each other, not to mention showing off your toys!
This month is a special month for Fathers. For those of you that are Fathers….Happy Father’s Day! For
those of you that are not, I hope you have the opportunity to spend some time with yours or at least get in
touch with him. Enjoy the qualities you share, you may even learn something new about each other. As
we all know, our lives fly by so please take advantage of whatever time you can with them. Perhaps you
can even bring them along to the field!

Special Notice Concerning DX8 Version 1.0 Servo
Travel Adjustment:
While adjusting a servo's Travel Adjust value in the Servo Setup screen, if the clear button is depressed,
both the value and the channel's reversing will reset to their default values of 100% and normal.
This reset could cause an unsafe condition if unnoticed, particularly if the channel has been reversed on
the throttle.
Movement:
Recently, the Horizon Hobby Service Center has received a small number of reports from customers
claiming un commanded servo movements and loss of RF link during the activation of the vibrator
motor in some DX8’s from the initial shipment. Horizon requests that all DX8 customers with the
Product ID (PID) HS008X or HS009X found in the battery compartment carefully check their radios to
determine if their transmitter has this issue prior to flying.
Transmitters with a PID other than HS008X o HS009X are not affected by this bulletin.
If you have a DX8 with the affected PID, please perform the following test.



Step 1: If your model is electric, unplug motor leads from ESC for safety.
Step 2: In the function list, select Timer Screen and set a 0:10s Count Down timer to
Tone/Vibe.
Step 3: With model powered on and connection established, activate timer and observe
servos for un-commanded movement and receiver for loss of RF link.
Should you find that your transmitter is affected by this issue, please contact your nearest Spektrum
authorized service center to arrange for a free upgrade to your DX8 performed by a Horizon Hobby
authorized Technician.
