pepperF1SH – Part I: Frame & Motors

This post is the first in a series of posts about the adventure of building the world’s lightest brushless FPV quadcopter: project pepperF1SH.

Banggood recently released a new nice, cheap and lightweight brushless motor, the Racerstar 1103 8000KV ( also available as a 10000KV version). First thrust tests on the 8000KV motor on 1S showed that it might be possible to get a flyable 1S copter, no 10:1 killer machine but probably good enough for some indoor fun.

Therefore it is time to design a lightweight 1S brushless fun copter! Stock electronic components are all bulky and/or heavy, and it removes the fun part of designing your own electronics. As you might have read i started to build a tiny 4in1 20x20mm 1S blheli_s brushless ESC and a tiny 20x20mm F3 tinyfish flight controller with integrated frsky compatible receiver based on my usky rx (!). They will be probably <2grams each.

I am going to start with the frame design on the upper right. When this is cut in 0.8mm CFK it weights 2.9g. Together with four 8000KV motors this sums up to 16.9g with screws:

I hope to end up with a total AUW weight including the FPV gear of 30-35g. Lets’s see how it goes 😉

to be continued…

    Where did you get this cut? I’m working on something similar! Hopefully I can get your fc working on it.
