Love the plane but the battery tray was horrid.

Nice practical cut.

Out of curiosity - what did the old one look like? Was there a significant weight change by switching?

The old one was molded plastic, this adds several grams but far less than the difference between using a 1800ma and a 2200ma battery so it won’t be noticeable.

Great job! It is so nice to solve our problems at the home base.

Perfect!

Is that long silver rectangle the battery?

Battery is not showing, let me get it all mounted up and I’ll post a quick with the battery installed.

De plane, de plane. Great solution!

mounted and ready to fly.
the project consists of 1/8" Baltic Birch plywood, some velcro, a zip-tie, a few drops of thin CA, and a few drops of E6000.

That is seriously ultra-light. The plane itself. I’m surprised the wires holding up the propeller don’t get all twisted eventually!

That square aluminum tube that acts as the fuselage is amusingly strong but yes, everything is parsed down to a minimum.

So if that is the case, a pair of 3D printed parts might actually shave even more weight off (negligible, but still)

I think we have enough experts in different fields here that we could probably design a pretty darn awesome RC plane with almost all of the airframe coming off the 
or a 3d printer.
Fully 3d printed planes are a thing but I don’t like the idea as they are so fragile. Makes a lot more sense to me to 3d print bits and pieces.
RC planes have traditionally been made from balsa but I wish I knew more about materials engineering as I think it would be quite cool to design a plane using more common materials.
