Building Yak-18 (Max) 1.2 m wingspan.

Hi everybody.

I'm starting to build a Yak-18 (Max) out of foam board using SD 3V plans. I am a newbie in building and there are a lot of new things I learn as I go through. I'll share the pictures of my work progress with you. Your thoughts and suggestions are welcome .

I wanted the wingspan to be 1.2 m so I scaled the plans with Sketchup and measured everything.

Also for the motor mount I'm not sure if I should use foam board as pictured below or should I replace it with wood. The front part is made of wood anyway.

I found a piece of foam (20 mm thick) that has a plastic layer in the middle and I thought of making wheels out of it.
