6.2 Push rods for ailerons
In contrast to previous
models, we have
increased the diameter of
the pushrod and avoided
bends
.
By this, the
maximum force can be
transmitted without bending
of the push rods.
For this we need a special
small ball connector
and
a handmade direct
linkage
made of aluminum tubes
.
Glue the
brass part
of the ball connector into the
aluminium
tube
. We recommend to use epoxy glue, as superglue might be
too brittle for this small joint may be too brittle.
At the other end we chose the
standard version with 1mm steel
hook
and
securing wire
. At the other servo-connection you can
just make an S-hook.
Push the
steel hooks into the carbon tubes
and the
carbon
tubes into the aluminium tubes
. Grind all gluing spots and use
epoxy
glue for this bonding.
In order to achieve the correct length of the push rods, let this last
bonding
harden in the assembled position
. The servos and
ailerons must of course be put in
zero position
.
A
0.3mm steel wire
will serve as
protection
against dismantling.
The parts are held together with a shrinking tube. Fix it the wire
with a drop of super glue.
