Heli-Launch & Heli-Cam
I have also designed an apparatus which will enable my helicopter
to launch either one or two foam wings via a 'twin claw-like device'
mounted underneath the undercarriage. The aim of this is to develop
a competition, be it pylon, aerobatics or whatever, incorporating
the Heli-Launch System. As well I am developing both a video and
still shot camera system. Trials are presently being conducted
on all of these ideas. When they are all working perfectly, I
will share with you the finished products. Stay tuned!
Multi-Mode Flying
INTRODUCTION: Well, here it is. My multi-mode mixing setup. The
diagrams below show how I have it set up in my glider. I had limited
space to fit everything in. However the more I think on it, the
more configurations I reckon I could come up with.
ASSEMBLY: The servos had to be mounted at the same height again
due to limited space. To get all of the rods to by-pass the servo
arms without obstruction, I’ve used a combination of metal
rods with Z bends, ball links, and quick links. The servo arms
are a combination of standard and homemade arms.
HOW IT WORKS: The diagrams indicate how the system works and not
specifically how I’ve set up the rods, ball links, quick
links, Z bends etc., in my glider. With so many combinations,
and at the risk of describing a method which may be inadequate
for your model, I’m leaving it up to you to work out your
own method of construction.
RATES: You will have to mock-up some cardboard templates and play
around with them on a table to get the desired rates for each
channel. I haven’t done much experimenting with this, however
my initial set-up has the rates of each pair of controls moving
differently to each other. I.e. The left rudder for example has
a different rate to the right rudder, and so on. It’s just
the way it worked out. I know if I spent a lot more time experimenting,
I could fine-tune the movements to be the same. Don’t be
too concerned about where the centres of any particular servo
arms sit. If they are not where you think they should be, it will
simply mean that your set-up may experience some unwanted differential
or exponential - but it will still work.
 

Above: This is how my glider is set up. It's
a bit cramped but it does the job. The drawing on the right shows
a pictorial view of one function.

Above: "U" shaped bracket held
in place by either rubber bands or double-sided tape. Centreing
material can be rubber bands, but fine tension springs would be
preferable.
TRANSMITTER: If you've done everything correctly,
you should end up with your rudder control on your left and right
sticks, and your elevator control also on your left and right
sticks. Now you can practice being ambidextrous. If you use mode
one, the right control stick will have to be temporarily centred.
On my transmitter, I was able to unscrew the control stick (which
separated halfway down the shaft), insert the springs, then screw
the top part of the stick back on. See diagram.
Electroni-Comp
Combat, Pylon, Limbo. You name it. The sky's
the limit.
Then again, maybe there is no the limit.
Combat: Some time ago I got into combat
- slope soaring style. Whilst it was a lot of fun and increased
ones reflex skills quite dramatically, it did have its downsides.
It could take ages before getting a strike, then when you did,
usually the other person would gain control of their glider (the
one you hit) fairly quickly and continue flying. As is was almost
impossible to know who hit whom anyway, the general rule was that
in order to score a point, someone's glider had to crash to the
ground. Provided you were flying foam wings or the like, this
was not such a problem, although eventually your glider would
need some repair no matter how strong you think it was. So I decided
there had to be a better way to do combat. So I design a system,
then hoped for an electronic genius to come along and advise me
on the best way of going about it. Well fortunately I found such
a genius - well I thought so anyway. His name is Steve and he
is very clever when it comes to dabbling in electronics. The criteria
needed was lightweight hardware, durable construction, consistent
operation, audible from a long distance, affordable price, accessible
parts, quick to re-produce and easy to install into an aircraft.
Well I' m getting a headache just thinking about it. The answer!
A personal alarm. Sounds too easy doesn't it. The only problem
we had to overcome was to enable the alarm to stay on for a designated
time - say 5 seconds, after the strike had been made. Steve overcame
this problem by altering the system with a clever piece of circuitry
that was built into the unit.
The aircraft has a series of stick-on aluminium strips layed along
the front, top and bottom of the leading edge of the aircraft.
It also has a seven metre tail made from control line.
Pylon: Of course this system
now congers up all sorts of ideas for the radio control enthusiasts.
It could mean for instance, that in pylon racing,
the flag-persons could be made redundant. Instead, a live electronic
pole could be placed at one end. The aircraft would be required
to make contact with the pole, in which case an alarm would sound,
thereby letting the pilot know that he can return his aircraft.
Various Applications: Other
events such as limbo, or something that you may
simply make up on the day, could use this system. The best thing
about electronicomp is that it is conclusive, reliable and means
more people fly and less people organise. If you know of a more
efficient system such as a laser-guided device, your information
and accompanying photo/s would be most welcome.
