Pushrod Exit Slots
The pushrod exit slots marked in the Evo plans are
designed to accomodate a 2mm size pushrod and are
for use with a ball joint at the elevon end. As marked,
the pushrods are coupled to the elevons at near half
span and so eliminate control surface flutter at high
Servo Mounting Straps
We recommend using 4.5mm wide cable ties to hold your servos in place. These are very strong and their width ensures that forces are spread over a large area to discourage tearing of the twinwall material.
Using a screwdriver or a similar instrument of about
3mm diameter, make holes through your twinwall sheet
at the points marked as servo mounting holes on the
Evo plan. Please note that these holes are correctly
placed for the use of standard 9g micro servos and
Mugi pushrod kits available from us. Note the orientation
of the servo cable ties - so located that when tightened,
the free end will point towards the rear of the aircraft.
If you are using different servos and/or pushrods from
our standard then you'll have to use trial and error
to find the correct placing for your servos.
Check the Servo Horns
At this stage it's a very good idea to make sure that
the holes in your servo horns will fit the pushrod
connectors you are using. With Mugi pushrod kits and
micro servos you will most likely have to make the
holes a little larger. This is easily done by carefully
rotating a scalpel or sharp blade in the hole, constantly
checking for fit until the connector will go through
the hole without jamming.
