This is a scale Lockheed Vega.
"C" power pack with 2200 3s battery
WS: 49.5" (1257mm)
Len: 34" (864mm)
AUW: 2lbs 11oz (1213g)
I experimented with the wing and designed it with sharp trailing edges. The bevels shown in the plans will meet so that very little sanding is needed. I coated them with Mod Podge and covered with paper for strength. Thanks to @rcprandtlplanes for the inspiration.
The battery is inserted and then the wing attached (sorry, couldn't think of a better way). The wing has a 3D printed front center that has an alignment tab that fits into the windscreen/cockpit and has a 4mm nylon bolt that holds the back.
Because it is scale I used the 3D printed radial to balance. Paint and assemble the plane. Put the battery in the middle of the battery tray and attach the motor to the firewall with 2 thicknesses of foam board between them. CG is 1/3 of the cord so balance it there and add weight on top of the foam board spacers until it balances. Then adjust the weight of the weight of the printed motor by adjusting the percent of infill so that it equals the weight you put on the nose minus the weight of the cowl.
The landing gear is optional. For the springs I used 25mm long x 7mm OD x 0.7mm wire x 12 wraps (from Amazon). I used PLA+ with 25% infill and printed the A arms and hubs at an angle for more strength. You will also need 6 - M3x20 nylon screws.

Part - Sliding Battery Tray
The tray is designed to fit a battery inside a location that would be hard to strap in or to get back off of the Velcro. It's inspired by Golden Age planes where the weight has to be as far forward as possible. This allows you to strap the...
