Time to do the final construction. The last step will be the battery tray and I want everything else done so I can balance the plane with the battery and tray. The motor is installed with an APC 20.5 x 14. I like the Great Planes spinners and choose the white one for this plane. Red also works. The speed controller is installed with 2 nylon ties in front of the landing gear on the bottom of the fuse. Rudder cables were made from Berkley 35# test Steelon fishing leader. They are crossed and a small crossed guide is made from yellow nyrod material to keep the wires from rubbing on each other. The stabs were mounted with servo extensions to the elevator servos. A couple of pieces of foam tape just protruding past the lip of the stabs will hopefully reduce wear on the fuse. Similar setup can be seen on the wing root pictures. The elevator extensions added 13gms.

I made a small equipment tray from CF honeycomb material to mount the receiver, flight pack battery and Jaccio 6.0 volt regulator. The tray with velcro added 7 gms. I never charge the flight pack battery in the plane so the charging lead from the switch/regulator was cut off (4 gms)

The wing root needed a little work. First the nylon bolt is mounted into a rib and set back from the wing edge. First time I started tightening the wing to the fuse didn't sound too good. There is a space between the base of the bolt and fuse side, so this space needs to be built up with light balsa to be flush with the wing root. In addition several small pieces of balsa and foam wing saddle tape were positioned around the wing root to cushion the wing to the fuse junction.
Final weights of the wing ready to fly are right 454 and left 466 gms.

Final steps will be to cut out some air exhaust openings on the bottom of the fuse and then the battery mounting.

Weight will be right at 5kg give or take a few grams. Current weight for the plane is 3780 gms. A Thunder Power pack with connectors is 1190 gms and a True RC pack is 1195 gms.
This will leave me with a 30 gm leeway for battery mounting. I could have saved a few grams using the included control horns. Using the included steel wheel axels and landing gear mounting bolts would have made it more difficult to make weight. The cheaper slightly heavier battery packs would also be difficult to make weight with. A simple (not cheap) way to lose 60 gms or so would be to change the speed controller to the 80 amp YGE www.f3aunlimited.com A lighter PBG composites wing tube will also save 21 gms or so.
