The lightweight fin-post has 4 phenolic hinge posts already installed and aligned for
you. Just slide in the 4mm brass tubing for a perfect 'scale' hinge.
The molded carbon motordome is already trimmed for you at the factory, and provides a rigid
mount for the current motors. Please mount your chosen motor to the mount using the
instruction is included in the motor section here - and follow the latest motor manufacturers
recommendations about this exactly.
The nosegear mount is also pre-assembled for you, bonded into the bottom of the carbon
motor mount and is more than strong enough for even less-than-perfect landings! Bild?
The 2 part cowling is also pre-assembled during manufacture, with the main of the fixings
already completed.
The Stabilisers:
The stab parts are also vacuum bagged sandwiched construction, with the control horns and
hinging completed for you. The rudder is hinged with a 4mmØ brass tube, and the elevator
control surfaces are hinged with 4mmØ aluminum tubes, all fitted through 4 phenolic hinge
bearing plates which are jig-installed during manufacture for perfect alignment.
All the structural parts are preinstalled. The horizontal stabs are mounted with a 20mm
diameter aluminum tube and one 10mm carbon anti-rotation pin each.
Servo Screws:
Fix all the servos into the milled plywood servo mounts using the 2.9mm Ø x13mm sheet
metal screws provided in the kit, not the standard screws normally supplied with servos by
the servo manufacturer! This is because all the holes in our milled servo mounts are 2mm
diameter, due to our CNC manufacturing process, and this is too big for the normal
screws.
Take Care:
Composite sandwich parts are extremely strong, but fragile at the same time. Always keep in
mind that these airplanes are designed for minimum weight and maximum strength in
flight. Please take care of it, especially when it is being transported, to make sure that none
of the critical parts and linkages are damaged. Always handle your airplane with great care,
especially on the ground and during transport, so you will have many hours of pleasure with
it.
