The Sea Hawk nose section added.
The canopy and part of the top skin act as the battery hatch and to give access to get everything in
A simple two colour scheme. Dark Sea Grey upper, Sky below.
The ESC is mounted into the cockpit wall with is cooling fins just ahead of the RH inlet.
The battery box for the 1800 mAh 3s is slightly offset to the left to counter the weight of the ESC.
Despite the inefficiencies of the ducting it actually flies quite well. Gentle and predictable not unlike the full size.
With clean aerodynamics and a very low wing loading it glides like .... a glider!

That looks like it flies really nice!

Ooooo, nice. Foamboard? You made the plans yourself or are they an availability download?

Out of Foam Board!
It's Ben Harber's baby bugatti 20" with some minor modifications made so I can fit more in the battery bay.

Making progress on the 'Cat. Getting a few finishing parts 3D printed. Nice plans , The Hanger!

I just looked it up. And I cannot believe the sr81 flew.
The wing loading was 85 pounds per square foot, and the thrust to weight was 0.44

Oh wow, I never looked at those. I was more meaning how it was able to achieve those speeds with that power.

The aerodynamics of supersonic flight are complex indeed.
Remember Concorde had the fuel to cross the Atlantic at Mach 0.85 or Mach 2 but not at any speed in between as the combination of drag and engine performance was too inefficient. Concorde had a take off thrust to weight of only 0.33

Yeah, the aerodynamics side of this is what I usually try to stay out of. It’s too complex for what I do. If it flies, it flies is usually what I use. Exept on my ultralight designs.
