I must say I am pleasantly surprised how well the cheap A8 is performing. The only bit I have actually replaced is the extruder heating element. Entirely my own fault as I broke one of its wires when i changed over a nozzle..

Yes it will have all the flaps. Full span on the lower wing, half span on the upper.

From this video it appears the upper flaps travel a bit more than the lower. I don't think the ailerons droop.

Now comes the tricky bit the scale printed undercarriage.

With the lower wing centre section in place all the undercarriage mounts are available so after many hours of both CAD and printing........

UClegs1

All printed, even the pins are cut off bits of filament. The only metal will be the stub axles'

The printed spring units are in about the fully relaxed position but should give nearly 1" (25 mm) of travel once the appropriate rate springs are installed.

Part of the design philosophy is that it should shear off before tearing out the fuselage mountings as I can always print more undercarriage. wink 2

With temporary too strong springs in the spring units the fuselage can sit on its printed/Depron wheels.

UCwheels

The tailplane and elevator. 2mm Depron skins over a Depron shear web.

Tailplane1

The 5 g elevator servo.

Eleservo1

The tail plane is braced.

Tailbrace

The brace is also 3 mm Depron but with a balsa leading and trailing edge.

The elevator halves are joined with a short section of thin wall glass fibre tube.

To keep things light and simple the elevator is top tape hinged with invisible (matt) tape.
