Last year I built the Guillows DR1 balsa model kit and had fun flying it with my brother and getting slomo footage of it too.

The electronics came from an older UMX Pitts from Eflite. It is a standard 2cell brushless setup with linear servos.
I made a servo tray and motor mount to support the electronics and carbon rods with steel wire ends connect the servos to the control surfaces.

I covered it with the included red tissue. I used glue stick to apply it, water mist to shrink it and then Tamiya spray clear coat in order to seal it. I used the included decals, and painted the plastics with Aluminum color.
The engine detail was 3D printed on an Ender3 and painted black with silver weathering.

My initial setup for these flights was a bit too tail heavy, and on this gusty day I found takeoffs easy but landings difficult. regardless, I made a handful of successful flights with it and it's still in 1 piece.

I think it ended up at 130g or 4.6oz, and may fly better with some expo on the aileron channel.

If I revisit it I will add a small amount of nose weight, the missing cabane rigging/cables, machine gun, and a pilot with scarf
