Braided sleeving in progress

Braided Sleeving Tutorial and Tips

Braided sleeving is a low-cost way to add a professional look and feel to your electronics project. It can be frustrating to work with, but it’s pretty simple once you have the proper tools and techniques. In this tutorial, I’ll walk through the process of applying braided sleeving to a brushless motor and ESC. Tools Read more about Braided Sleeving Tutorial and Tips[…]

RunCam Split 2

RunCam Split 2 FPV+HD Camera Review

The RunCam Split 2 by RunCam is the second iteration on the only viable solution that marries an FPV camera with an HD action camera using a single lens. This is an attractive offering for those looking to consolidate their builds. It’s also ideal for getting HD recording capability on smaller frames. I thought it Read more about RunCam Split 2 FPV+HD Camera Review[…]

LiPo Characteristics Part 3: Internal Resistance

LiPo Characteristics Part 3: Internal Resistance

In Part 2 of this series we took a look at how LiPo cells behave electrically over a discharge cycle. There were a few observations (like voltage sag) that can’t be explained by applying Ohm’s Law directly. Internal resistance is a metric that aims to explain some of these properties. Why is Internal Resistance Important? Read more about LiPo Characteristics Part 3: Internal Resistance[…]

LiPo Characteristics Part 2: Electrical Properties

LiPo Characteristics Part 2: Electrical Properties

In the previous post of the series, I outlined some basic information about this study. In this post, I’ll start diving in to the data to see what it tells us about LiPo characteristics. I’d recommend you give part 1 a read to familiarize yourself with the method I used to collect data. A word Read more about LiPo Characteristics Part 2: Electrical Properties[…]

Hypetrain Freestyle Motors

Rotor Riot Hypetrain Motors Review

I recently picked up a set of Rotor Riot’s Hypetrain Freestyle 2306 2450Kv motors for my freestyle quad build. Rotor Riot designed them and T-Motor manufactured them. They offer a unique and elegant design and claim to have a good power-to-efficiency ratio. You can get the hypetrain motors for $25.99 USD each from Rotor Riot’s Read more about Rotor Riot Hypetrain Motors Review[…]

LiPo Characteristics Part 1: Introduction

LiPo Characteristics Part 1: Introduction

Introduction Recently, I became curious about LiPo characteristics and quirks. What causes the drop-off in responsiveness over time? Why does power seem to fall off a cliff at the end of capacity? Why do throttle punch outs cause my flight controller to brown out when the battery is low? What makes one battery better than Read more about LiPo Characteristics Part 1: Introduction[…]

DIY Charging Harness for 1S Batteries

If you fly micro/nano quads, you probably use a bunch of single cell LiPos. The balance charger I use for my 3S and 4S packs (Accucel S60) doesn’t support 1S batteries. In order to take advantage of some of the features of the charger (charge/discharge to storage, measuring IR, etc) I decided to make a Read more about DIY Charging Harness for 1S Batteries[…]
