Default RE: Functional hardware fittings on scale models

even if it's not scale it looks like it could've flown sometime during the 1920's
Thanks! Exactly the look I was going for. I originally wanted to build a scale Pietenpol, but it turned into a hodgepodge instead.

About the model... this model has a span of only 36", it is powered by long-can 400 electric mounted to Mini-Olympus gear box. On 9.6 volts provides more than adequate performance for "scale-like" flight. (If you have never heard an electtric model flown on the Mini-O...some folks complain about the noisy gear box, but it actually makes IMO a pleasant "engine" sound). Prop is 9" diameter. AUW ~29oz. I think wing loading worked out to about 16oz/foot. The model flew well, but sunk quickly at dead-stick and needed to be flown in to landing pretty fast. Gear placement worked well and did not have too much trouble with handling or nose-overs.

I have a couple of pics "in the bones" but they are pretty lousy. Nothing remarkable about the construction, it is basically slab-side construction of front of 1/16" balsa, with the rear fuselage being an open truss constructed of 1/8" pieces. The vertical tail outline was achieved using 1/16" balsa laminations.

The cabane struts are spruce, glued into the fuse, but attached to the wing by 2-56 bolts into blind nuts in the wing. Landing gear struts are spruce, attached to fuse by small steel brackets and #0 screws. Landing gear is sprung with bungee cord.

Hmm, let's see what else. Wing struts are basically just for looks, they are aluminum tube with 1/8 dowel inside for extra rigidity. The attachment points are simply #0 screws through the flattened ends of the ALuminum tube. Problem with this is the Aluminum could bend or break very easy on then ends. The "outboard" aileron placement was achieved using a centrally mounted servo acting through wire links and bellcranks.
