This post is the tenth (wow!) in a series of posts about the adventure of building the world’s lightest brushless FPV quadcopter: project pepperF1SH.
The CFK arrived today — time to assemble the previous bumper cage prototype! It turned out to be a bit lighter than calculated: The whole assembly parts weight only 2.83grams:
The bad thing is that this is close to the capabilities of extrusion printers, I think I will order those parts from shapeways as well. This could save some more weight as I can design them with thinner walls (0.7mm VS 1.0mm).
Enough numbers, let’s see how it looks assembled:
Even though this sounds quite good, I will continue the hunt for weight savings… I have some titanium M1.6×2 motor mounting screws on the way to me, this should save ~0.4grams for all eight screws (compared to the inox M1.6×4 I use now).
