| ANTENNA TIPS
(FASTENERS)
. A dress maker's straight pin poked through the hollow
section fuel tubing so that the ball end fills up the I.D. of
the tubing .Insert the antenna wire started through the fuel tubing
and there will be enough friction to keep the wire from pulling out.
Now, simply stick the pin into the top of the fin, or the side of
the fuselage and pull the antenna taunt. The antenna will stay where
you put it, but will move without breaking in the event of a large
bump to the airframe.
(INSTALLATION))
Never exit the receiver antenna wire to the exterior of the
fuselage by running it out via the wing saddle, or anywhere near the
wing-fuselage joint. The vibration and relative movement between the
two during flight will eventually sever the antenna wire. The proper
method is to punch an exit hole in the fuselage, near the receiver
location and away from exhaust residue. Obtain from any electronic
store heavy sleaving material of the size that will allow the antenna
to slide through. CA about a three inch piece of this sleaving in
the antenna hole such that about a 1/2" or so is inside the fuselage.
Pass the antenna wire through the sleaving and attach to the rear
of the fuselage . However, before you pass the wire through the fuselage,
put a strain relief on the wire inside the fuselage to prevent it
from being pulled out of the receiver. The best and cheapest strain
relief is either a button or a broken off portion of a servo output
arm. Simply weave the wire through the holes in the button or servo
arm about three times and its done. Make sure you position the strain
relief on the antenna wire such that there is some slack antenna inside
the fuselage when all is done.
( USAGES)
Do not throw away broken Tx aerials. They are a good source
of thin brass tubes which are very useful for bushes, small pushrods,
tubing, guides, etc.
Here's a few more hints on Securing the antenna wire.Use heat shrink
tubing the size that just fits over the antenna wire (usually 22 ga
wire). Heat the heat shrink tubing on to about the last inch or so
of the antenna wire, leaving about three inches of the heat shrink
extending beyond the antenna wire itself.
You can then tie as many knots as you want in the heat shrink . Also
The inner tubing of most flexible control rod (i.e NYROD, Goldenrod,
etc.) makes a great fastening point for the receiver antenna. Glue
a short piece (1/2" or so) to an appropriate place on the aft section
of the fuselage (vertical or horizontal stab, fuselage side, etc).
Run your antenna wire through the piece of tubing. Then wrap the antenna
wire on the downstream side of the tube with just enough masking tape
to prevent it from easily pulling back though the tube.
INSTALLATION
TIPS
(BATTERY and RADIO PLACEMENT)
Keep your weight forward. To balance a nose heavy aircraft, 1 oz.
at the tail could be all it needs. While the same aircraft,
if tail heavy, could take as much as 10 oz. or more to balance.Temporarily
place the battery, receiver and servos in place and check the C. G.
without adding dead weight.With everything Assembled.. it is easy
then to add weight where you need it. Check also if the model is balanced
laterally and add weight as required at the wing tips.

SERVO POWER
Multiple servos for single control
functions are not uncommon.. For example, splitting the elevators
using a separate servo for each side for control redundancy, or utilizing
one servo for each aileron to eliminate complex linkages are now commonplace.
For those of you that follow this practice keep in mind that your
receiver expects a certain power draw for each channel. When you utilize
a "Y" connector to connect two or more servos to a single channel,
you increase the power draw at that channel substantially. Further,
if you start doubling up servos and those servos are the big quarter
scale variety, and then use long servo leads, then put the whole mess
under flight loads, you can overload the power output section of your
receiver and cause component failure. The power draw can be measured
easily enough with a ammeter.
The drawback to multiple servos is that you may get a drift in one
or the other control assembly (Especially with large
servo types.This can lead to a crash. one servo. Modern computer
radios ease this problem by allowing you to use two separate channels
for the same control by mixing them together on the transmitter.
Keep this in mind as a possible cause if you are getting inconsistent
performance for you radio system.
