Conwing L-16 (SeaDuck)

Since my old CL215 crashed after a broken wing in flight and the MartinMars is too big for small lakes, I will start a new seaplane, probably at 60in wingspan. I like twins and never make a twin-boom twin, so looking for twins on net I found the Talespin airplane, a Conwing L-16 named "The SeaDuck".

Really not... The front and top view are on same scale, the side view is larger, so I took most measures from top and front.

I printed the front-view enlarged to check the visual effect and liked a lot.

I am cleaning my modelling room to start it (need to fix my E-starter and link my Beech18 first), but will start it tonight probably.

EPS foam (white insulation foam), normally used on office air conditioning installations and electronics equipment packaging.

It is cheap, light, easy to cut with hot wire, easy to sando to any shape, and floats by itself, I use on most parts of my airplanes.

The hull is in advanced state, now I am sanding the corners to make a better fit and gluing all together with hot melt glue.

The flat hull will make mine look like having a smaller nose. In the other way, it will stay horizontally in water without tip floats :P

I usually make some adjusts to avoid this effect, like decreasing the height, but in this case it os not possible, since the prop may touch the water...

New pictures from today...

Corrected the nose shape, glued all together but leaved hatches for internal access on front and over cabin.

This will provide me space to fit battery where needed to set CG and make entry points to fix-ups.

The fuselage will hold only the battery pack. Due to the twin tail boons, all servos will be fixed on wing, motors too, so the better place to receiver and ESC is on wing too...
