This blog is dedicated to capturing many of my technically interesting, engineering endeavors outside of my real engineering career. I will hope to showcase my diverse interests, skills, and ideas, in big and not so big engineering projects.

Mini Quad Build > Cleaned Up ESC Wiring
Cleaned up ESC wiring by directly solder motor wires to ESC, which involved cutting and exposing nice ESC shrink wrap.
Re-shrink wrapped only bottom half to keep ESC LED's uncovered.
Removed ESC mounting pad.
Total vehicle weight savings = ~1g

Mini Quad Build > Frame / PDB / Motors / ESC's
2 hours of soldering, with not the prettiest ESC to motors connections because of space constraints. CC3D flight controller has menu select for "reversing motor rotation" so doesn't matter how the 3-wires connect.
Note convenient use of frame posts to hold ESC's.
Need to always reference this, so putting this here.
Each ESC had ~4-5g of wires coming off, so ESC weight assumption was high.
I may save a couple more grams when I shorten those ESC control wires and removing ground.
(No ground looping to ESC!!)
Surprisingly, overall matches to the original loose weight tally up to this point, which mean we on track to be overweight!
