I'm curious.

I'm building a GPs elec. Cub, my plans show a "rectangle template"
for the side (middle) window. My question is, are the front (triangle)
and rear windows left open ?

Thanks for all input.

As a guess I would say aerodynamically you'll have more drag without the windows (front windscreen, rear & side), but they are not required. Structurally, it depends on the kit and how the designer chose to hold the fuselage to the wing. If the kit calls for an opening in an electric it could be for heat dissipation and I would go as designed.

Thanks, The manual or the plans make no mention
of the other side windows. Just the rectangle template
for the side where the door would be. The hatch on the
bottom is vented to help cool the Esc and battery. The
wing attaches with a Dowel up front and 2 screws in the
aft section of the wing.

I'm going to suggest that the directions are missing the part where they tell you how to put clear window material in the little triangles and in the "D" sort of shaped rear windows.

You can trace templates for each of them on card stock, cut them out, and make a clear window the same size. There are a number of ways to secure them to the openings. Most involve supporting the window with scrap balsa or some other material, so the window is flush with the exterior.

Good luck,

My advise would be to make the windows as suggested,it would have better performance[less drag]. If you wanted to spend the time
you could cut out a shoulder and inset the windows flush,even less drag. But I think they are just cemented on over the frame.

Aerodynamically, it's worthwhile to have all those openings closed.

Are you going to cover the airplane with UltraCote or Monokote? If so, then you may wish to do that first so it can be wrapped into the openings.

You also might consider using clear UltraCote for all those windows. Cover with your color film and then simply iron on a piece of clear over the whole set of openings. It's almost zero weight compared to hard plastic (which isn't going to weigh much, but everything adds up), but is about 1000% easier. and neater. and can't cause a mess.

Thanks, I'm leaning toward using
clear monocote.

BTW


Anyone have pics of clear monokote windows or
the plastic installation flush to the outside fuse ?

TIA
