Building Extra Sports 30, cont'ed

MAIN WING Cont'ed

Measure and cut the covering as per the instruction manual. Epoxy the plywood and G-clamp for stronger bond. Here I used 4 minutes epoxy. * Carefully cut the covering and not the balsa. This can weaken the wing and might come off during flight. Once the epoxy set, drill two 4 mm holes as per instruction manual for wing mounting screws.

G-clamped

Back to step #4, glue together the 3 pcs of wing servo tray. I used 30 minutes epoxy. Cut a little bit at the 4 corners of the servo compartment as shown and glue the completed servo tray in it.

STABILIZER cont'ed
I skipped the elevator installation. - refer to aileron

Cut away the covering

Follow the instruction manual. Dimension from mid firewall to trailing edge +- 90cm left and right(A=A1) When done, marked and epoxy. (30 min. epoxy)

Use rubber bands to keep it tight and bond stronger.


VERTICAL FIN step#9

Test fit before epoxy. if OK, use 30 min epoxy. * Make sure it is 90 degrees to stabilizer.

Rudder installation: refer to aileron installation.


TAIL GEAR step #10


Measure and cut under the rudder to make a groove.

1mm pilot holes pre-drilled. I relocate and drill another holes to match the rudder for perfect fit. Epoxy the wire to the rudder.

Next fix the wire clamp. Just drill and fix the screw and nut supplied.


I skipped the installation for elevator, rudder push rods and the horns because it is so simple.

Below, engine mount installed.


As I used a 2 - stroke GS40 Supertigre ring engine, I installed the engine mount upsidedown.

GS 40 installed in placed. Pushrod installation need drilling on firewall to match your engine used. To be cont.'ed
