This airplane still strikes me as being kinda small,,, untill you put the cowling on and see how much space there is in there!

Throttle servo is placed on the bottom of the engine box. I did have to relieve a little of the tri-stock bracing the engine box.

Fuel tank is pre installed, three line system. You add the tygon.




Fuel dot,, being a prototype, we will ask EG to leave a little more wood for mounting fuel dot and switches.

Photo of the root rib of a stab.
Notice the notch cut out for the servo wire.

Lots of good hardware. Nice anodized aluminum servo arms are included, these would work well with the Uni Hub,,,, but I did not have any Uni hubs around so I used SWB servo arms.

Hardpoints are pre slotted. Just cut away the Ultracoat with a sharp #11 blade.

The fiberglass arm in this prototype needed to be trimmed, they were slightly long. Also some 120 grit sandpaper was used to scuff the bonding surfaces.

Assemble two arms with the supplied hardware and ball link, and glue into the hardpoints with some 30 minute epoxy.

Same goes for the rudder, dry fit everything first. Measure and mark before epoxying in place.

Ailerons get the same treatment.

I used 'Gorilla glue' on the rudder hinges.

The rudder servo tray is a sturdy piece of ply, still like to harden the screw holes with CA.

The stock rudder arms have the correct offset to keep constant cable tension.
I glued and screwed the arms to pair of Hitec wheels. Crossed rudder cables work well.

Looking into the aft fusalge section, note the guide tube for the elevator servo extensions,,,also the crossed rudder cables.
See any carbon fiber tubes adding strength and stiffness to the fuse?

Again, this is a prototype. What do you guys think? There is just enough there for the large, heavy duty switches now. Want the cut outs for switches (pre-cut)?

The tailwheel employs a tiller for steering, very positive. A small length of threaded rod and a ball link drive the tiller on this really cool carbon tailwheel.

Lots of goodies, Smart Fly power expander and optical ignition cut off. Also using their HD charge switches. Two two thousand something mah A123 batteries from Wrongway RC ( the schnizzle dizzle). http://www.wrongwayrc.com/

The ignition is powered from one of the batteries also, through a five volt reg. The batteries actually wound up under the rudder tray, puts the CG on the wing tube.

There are also some really nice fiberglass fillets for the fuselage/wing leading edge interface. I'll have to come up with a way to attach them, they look great!!

Everything else is simple,,,, four bolts hold the canopy/hatch on. Six on the cowling,, you have to cut the cowling for cooling.

Oh, BTW, the maiden went great. Pretty conservative,,,, new engine so no 3D.
