LX A10 build with Changesun 70mm 12 blade fans and Cyclone power 2000kv outrunners

Like the idea of having the ailerons split Eric.. For sure that will look cool.

A little bit of CF goes a long way in regards to strengthening up foam

Making progress with the air brake ailerons. Using the differential ailerons and air brake features of my old Futaba 9CAP I was able to get pairs of servos working each aileron, and accomplish the air braking split. The original foam ailerons will be the top aileron, while a Fiberglass sheet cut to the same shape will act as the lower half. The hinge line had to be the same so part of the foam was carved out to accommodate the hinges of the lower aileron. The lower ailerons are only hinged with two hinges so a CF stiffener was added to keep the aileron from bending. The foam top aileron will have the control horn at the inner edge and the lower Fiberglass aileron will have its control horn in the middle of the surface (both on the hinge line with the same distance from the hinge axis).

Love your work! keep pushing the envelope! on the build!

Wings joined and CF tubing used to extend the center section alloy tube as far into the outer panels as possible (till they touch the lower wing skin). This CF tubing along with the CF strips in each outer panel make the wing much stiffer than stock. The bare foam outer panels made ominous cracking sounds any time some bending force was applied before the CF spar was added. The EPS foam is pretty brittle. Next step is to connect the inner flap movement with the outer flaps. I will likely use some of the extra CF tube glued into the inner flap, sliding into the stock alloy wing joiners which were not used.

All wing wires buried and sorted. The receiver will be mounted on the wing along with the nav light power board and the electric brake module. Pretty happy with the split ailerons, in fact I can't wait to see this plane in the air (but still a lot to do on the fuselage and cockpit).

The stabs seemed a bit flimsy so a CF spar was added to all tail surfaces. The 1m piece was just the right length for all the spars needed.
Also reversed the position of one elevator servo so that all normal direction servos could be used without reversing or extra channels.

The tail and engine nacelles have been glued on. Wiring routed and tested. The nose was only tacked on to see how CG worked out with our GensAce 6s 5500mah 25c battery. The battery sits in the aft half of the cockpit so installation is pretty straightforward. The long battery lead was tested with a couple packs and the ESCs seemed normal without any extra heat.
The extra wiring due to the lights, machine gun system and electric brakes has created a wiring job, but thankfully it all seems to work.

Will be using the Parkflyerplastics A10 canopy as the stock just looked too wide.
Various pieces fabricated from styrene like the LE slats, flap hinge covers and panels for servos.

Looks awesome very nice Build
