Depron Spectre foamboard version

[cdfigueredo]

Hello friends, it’s been a while since my last post. A little while ago, I was searching for a pusher‑style FPV model that combined stable flight characteristics with agility. After some digging, I came across the Depron Spectre, which seemed perfectly adaptable to foamboard, so I’ve been working on it for the past few weeks.
I haven’t taken many photos of the build process itself, but this is the model I’ve been following. You can find more information here: https://newtonairlines.blogspot.com/2014/07/13m-twin-boom-pusher.html

For the twin tail booms, I joined two foamboard sides and made a sandwich using a thin sheet of Formica wood I had at home. This method makes them virtually resistant to any vertical or horizontal twisting.

Looking good still irritates the beegeazers out of me not being able to get depron.

depron should be 100% better than foamboard, but it is what it is. nedd to work with what we have.

I used a few 3D-printed parts: a motor mount with ventilation slots, a NACA-style air intake for cooling, and a latch for the canopy. I also plan to add more printed parts to protect the belly of the plane during landings.
I want to do a few maiden flights first to see how the model performs in the air, and if all goes well, then I’ll install the FPV camera and video transmitter.
