HOW TO BUILD YOUR RUDDER
SKILLS:
FIRST STEP: Practice knife edge flight. Fly at a speed where your plane has
adequate rudder authority. If this is at full throttle, then so be it. If
it's at 3/4 throttle, then that's better. Trim out your plane using the trim
guide on the NSRCA site so that your plane flies knife edge by only managing
rudder and throttle. If you use elevator or aileron correction use your
computer radio to make corrections. Practice knife edge over and over, upwind
and downwind, looking at the canopy and looking at the belly (this is much
more difficult). Do not go onto the second step until you are very
comfortable and your plane flies as it should. If you can't fly knife edge
consistently, you won't be an awesome pilot. You may need a more powerful
servo or a 6 volt battery or both to do knife edge. Practice knife edge along
with straight and level flight maintaining a precise heading. Be sure to
practice straight and level flight making heading corrections using the
rudder. You're plane should be trimmed out now well enough that it won't dive
to the ground when you are upright and want to yaw slightly by applying the
rudder. Most planes dive to the ground when the rudder is applied. Make
adjustments to this doesn't happen. Don't be a hero and try to compensate
with the sticks. Let the computer radio do it for you. There is not a top
pilot in the world who doesn't mix out his airplane's problems. You'll have
enough to do flying the plane without compensating for your plane's
inadequacies.
SECOND STEP: The first step is the most difficult. After that you have it
easy (for awhile). Now we move on to 2 point rolls. The CG of the plane
should be such that when inverted the plane should be close to hands off
which means it's a little on the tail heavy side for the average pilot (but
you're going to be an awesome pilot aren't you??? So make it a little tail
heavy!!). When you roll to inverted you need to use, dare I say it? THE
RUDDER! Yes! You said you don't need the rudder didn't you? SORRY, YOU NEED
THE RUDDER!. As you roll to inverted, bump the rudder the exact same amount
as you did during knife edge flight, but just when the plane is around knife
edge position. Not too soon and not too long or you will veer off course.
Just right. Hey, guess what? When you're inverted, you must use the rudder
there too!! Aaaaghhh. Yes, now that you are inverted you are now going off
heading and you must correct using the rudder. Wow, you just hit the rudder
the wrong way didn't you?? Well roll back over to upright, turn around and
try it again. Roll to inverted just before center so that you are inverted at
center. It's hard to tell whether you're coming in or going out isn't it?
You'll figure it out pretty quickly if the spectators start diving for cover.
It's easier to see if you're high up, and you'll also avoid those Oooh's and
Aaaah's from others as you pull instead of push and just barely miss the
ground. When in doubt, roll to upright and pull! Don't half loop. Do that 500
to 1000 times (not kidding), and you'll have it down pat. You may even be
down to less that 5000 feet when you're doing it! Roll slower and slower, and
fly longer and longer inverted. When you can fly at 500 feet out and 100 feet
high and can take 2 seconds to roll to inverted, then fly for 2 seconds
inverted, then roll for 2 seconds back to upright, and do this at 3/4
throttle, and stay right on line, you'll be able to do what most people in
the chairs behind you can only dream about. You are awesome! If you can do it
at 1 second intervals, that's excellent. Now is the tough part. Do it rolling
to the left, turn around and do it rolling to the right. Also do it from left
to right and from right to left. HA! You can only do it in one direction!
Practice another 500 - 1000 times flying from left to right and rolling left,
then rolling right, and flying right to left, and rolling right and then
rolling left. AND YOU'RE NOT DONE! While flying any maneuver which has you
inverted (which is most of them), you need to use rudder when inverted. Practice
all the time, you'll get it.
THIRD STEP: OK, it's been three years, but you're feeling cocky now, and want
more. It's 4 point roll time. That means knife edge to the belly!! Very
predictably you will do the first quarter roll to see the canopy, then the
second roll is to go to inverted, and then you saved the worst for last
hoping beyond hope that something will happen and you don't have to do the
third point of the 4 point roll. Now matter how you try to delay it, it's
coming, and so is the ground if you use the wrong rudder. Most planes do very
nice cartwheels, right up until the wings and fuselage fly apart. Avoid that.
Go back to step one and practice knife edge flight with the belly to you. You
don't have the practice knife edge with the canopy to you, that's too easy
now for Mr. Awesome. You've got to be able to hold it for 3 seconds. Also,
watch your batteries when you're doing this. The rudder uses a lot of juice,
and if you haven't used it before, you're in for a surprise. But you sensed
something was up in step one didn't you? Yes, that's it. Using the rudder to
only steer on the ground just didn't use up your battery much. A four point
roll should be done in rhythm. Count one, two, three, four. Count evenly and
slowly. Time it so that you are inverted just before center. Again, learn
this from left to right and right to left and rolling to the right and
rolling to the left. Use rudder mainly when you are close to knife edge, not
while rolling too much or you will veer off course. See you next summer.
FOURTH STEP: Rolls are next! They are called slow rolls which the 4 point
roll is a hesitation roll. How slow is slow and how you hesitate is up to
you, but generally the longer the harder/better. The slow roll is tough
because now you are feeding the rudder in sooner and ending later and you
can't stop to gather your thoughts in between. It's not much different, and
after a few hundred times, you'll only need a few more hundred times to get
it close to perfect.
FIFTH STEP: OK things are dragging on and on, you've spent $1000 in gas and
that's just driving to the flying field. You've almost crashed too many times
to count and your finger is sore from flipping the prop. Now it gets hard.
Really hard. You may want to bail at this point, but hang in there. It's time
for rolling circles. These babies are tough! We want to end up with 4 rolls
in one circle, one roll each 90 degrees. Start with 90 degree one roll
rollers. It's just like the slow roll from before just bent a little bit,
kind of like when you were trying to fly it straight but weren't too good at
it. To see how big to do it, try flying a circle without rolling and see what
seems comfortable. Then do a flat circle using rudder only and staying
upright. The radius is pretty big to do it smoothly. That's the radius to
shoot for. Once you master the first 90 degrees, you must learn it from left
to right, right to left, and rolling to the inside and to the outside of the
circle. This will take awhile, a looooong while. But after that, it just gets
harder. The worst is the final 90 degrees with the plane starting out heading
towards you and the flightline. The key is to practice the 90 degree roller
only, with the rest of the circle being flown banked without rolling BUT
after you master the first 90 degrees, don't roll the first 90 degrees, roll
the second 90 degrees only. Do the rest of the circle in a regular bank. Do
it from left to right and right to left, starting upright ans starting
inverted, upwind and downwind, in a crosswind and in calm weather. Then do
just the third 90 degrees and then the dreaded fourth 90 degrees. When you
practice the fourth 90 degrees, try to do it with no one else around. It
keeps down the shrieks and doesn't jeopardize too many cars in the parking
lot.
SIX STEP: Well you got the 90 degree rollers down, no it's time for the 180
degree rollers and then the 270 degree rollers keeping in mind to stagger the
starting and engine positions, which way you roll, and flying right to left
and left to right, starting from inverted and starting from upright, and
upwind and downwind. Keep mixing it up.
SEVENTH STEP: Rollers. Full blown you name it you have to fly it rollers. Now
it's time to put it all together and do a 4 roll roller. Now it's tougher
because you need good throttle management. You must be at full throttle into
the wind, and part throttle when downwind. You must start and stop in exactly
the same place. And now you must alternate the rolls too. Practice the first
90 rolling in and the second rolling out and keep changing. Then, just to
make it more difficult, you must also do 3 roll rollers, 2 roll rollers, and
1 roll rollers upwind, downwind, from inverted or upright, alternating and
with your eyes closed standing on one foot while singing Broadway show tunes.
Then you can be like Quique Somenzini and do a snap at each 90 while rolling
the rest of the circle and do it to the beat of the music. (You can put him
to shame by doing it with your eyes closed and the transmitter behind your
back.)
Once you master rollers, you can easily fly many maneuvers with a minimal
amount of practice because you will be good on the rudder. Rudder is the key
to flying precisely and becoming an awesome pilot. The better on the rudder
you are, the more awesome you are.
THROTTLE SKILLS:
The left stick is the throttle. It can stop between the top and the bottom.
Try it. Gas planes slow down very fast when the stick is at the bottom. Move
it forward a little when you are landing. For loops, if you have a powerful
plane, you should be at 3/4 throttle at the bottom while entering the loop,
then at full throttle when perfectly vertical, then reducing the throttle to
1/2 at the top of the loop, then at idle just after the top and when pointing
vertically down, then up to 1/4 through the bottom of the loop (especially if
you are now headed into the wind), then back to 3/4 throttle. Throttle
position changes with wind conditions. Fly in both directions and see what
you need to do with the throttle.
HOW TO PRACTICE MANEUVERS:
Practice by repeating the same maneuver over and over and over and over. Use
an entire tank of gas doing loop after loop after loop after loop. If your
loops are still bad, spend the whole day, week or month doing nothing but
loops. You will only learn through repetition of the same maneuver over and
over. Going from one maneuver to another will not help much. Once you have
mastered one maneuver, then go on to the next. You may have to combine a
couple of maneuvers like Immelman's and Spins, to be able to practice spins,
but the main point is that you need to do the same maneuver OVER AND OVER.
Sound boring but it really isn't. Try it. Do every maneuver from left to
right, and right to left, going to the left, going to the right (like rolls
and hammers) so you don't become dependent on one direction, and upwind and
downwind so you practice throttle management. The key is repetition.
