Power Systems Ebook by Dave Powers:
http://www.rcpowers.com/E-Books.htm
This is a best seller for us. This ebook
answers some of the most commonly asked good
questions we get. WHAT PROP, MOTOR, BATTERY,
ETC DO YOU GET FOR YOUR PLANE???
The secret to this is you build or buy the
ENTIRE airplane around a "magic prop." Click
on the link above for a "infomercial video"
on it.
We have 3 previous test flights of this
project here:

Ok, so what I am up to with this project is
to "BREAK THROUGH THE HIGH ALPHA BARRIER."
What that means is I am trying to get a RC
jet to fly at about walking speed with its
nose at 70-90 degrees (most all airplanes
stall and fall when they hit 30-45 degrees
because their wings are no longer getting
lift, see.
3 Ways I am doing this. All 3 are needed and
work together:
1) I have both my motors able to "Thrust
Vector", Google that term if you need to...
This gives me control with or without
airspeed by just moving the thrust of my
motors around.
2) I have the canards (pitch/up and down
control) and my ailerons (roll control) flip
back into the wind with switches on my
controller once the plane exceeds 40 degrees.
Without this, these control surfaces would
be trying to stall and crash the plane for
me, rather than facing back into the wind and
giving me control at high angles of attack
(40 degrees and above).
3) Gyro stabilization. So once I got the
above 2 to work, I then installed a gyro on
each axis: 1 for pitch (up and down) 1 for
roll, and one for the rudders (yaw). The
plane reacts so fast and wiggles around that
I need the super fast gyros to make
corrections within microseconds, and they do
just that. They work perfect, test
successful.
Another reason for the gyro stabilization is
I have my center of gravity (CG or balance
point) so far back that the plane is
incredibly unstable! WHY WOULD I DO THIS?
It's a trade off: More stability = Less
maneuverability. And More maneuverability =
less stability. So by having my CG far back,
the plane is always wanting to lifts its nose
in the air (which is what I want for high
alpha). The CG also makes the controls
respond MUCH faster (which is also what I
want for stunts). The cost is, it's so
squirrely and jumpy, that I can barley
control it on my own. The human reaction
speed is just way too slow to be able to deal
with the dozens of micro-corrections that
need to be done each second just to get the
plane to fly straight! Crazy, huh?
Well anyway, it all works, so how do ya like
that. Been working on this idea for about a
year. Turns out, all this I figured out on
my own is pretty much what the REAL SU-35s
and 37s do! Well, at least what I can figure
anyway.
The final stage of testing is training the
pilot (me) to be able to fly it better and
better and really discover its abilities. So
I'll fly this plane until it finally falls
apart or crashes real good. It's probably
got another month of life in it at best.
In the meantime, I'll be starting
construction on the FINAL one! I have a list
of about 50 minor construction improvements
for the new one. The final one will look as
good as I can make an RC jet look. I am
planing on the blue camo that the Russians
use for their Su-35s.

UPDATE 1
Hey I was just thinking for guys with just a
scratch built or store bought parkjet - you
could put just ONE gyro on the pitch and this
would allow you to move your CG farther back.
Farther back CG is going to make better use
of your flaps, way tighter loops, and more
maneuverable all the way around and at the
same time keep the plane under control for
you especially with landing!

Gyroscopic Training Club Seen on "Fore
Inventors Only" Comes to Market
SKLZ, the industry leader in sports skill
development products and equipment, today
announced it is now shipping its new Gyro
Swing training club to golf retailers and
consumers throughout the country. As a key
component of the company's line of Rick Smith
Signature Series golf training aids, the Gyro
Swing is the only training aid that truly
gives golfers the "feel" of an ideal swing,
forcing them to stay on the correct plane
with a perfectly timed release.
Originally presented by inventor Larry Kelly
as a finalist on The Golf Channel's popular
"Fore Inventors Only" show, the Gyro Swing
has a 20,000 rpm gyroscope in its clubhead
that uses the principle of conservation of
angular momentum to create a distinct and
forceful pathway for the club.
