Low Cost Arduino Based Auto-Stabilizing System

There are a lot of choices when it comes to picking a flight controller for your quadcopter.   If you are looking for a low cost way to auto-stabilize your quadcopter, this is the guide for you!

How-to Balance a Propeller

An unbalanced propeller produces excessive vibration.  This vibration travels through the entire airframe affecting the handling of the aircraft,  produces inaccurate readings by the sensors, and creates premature failure of motor bearings and parts.  A balanced propeller is paramount to a stable aircraft.  A balanced propeller produces less vibration and draws less current, which results in greater stability and extended flight times.  You should balance any propeller before installing it on your aircraft.  Balancing a propeller requires the use of a special tool, you guessed it a propeller balancer.  The propeller balancer that I use is the Top Flite Propeller balance.  It is essentially a shaft held by two magnets.  The magnets create a frictionless surface for the shaft to spin freely.  Read More…


Power connectors come in various of shapes and sizes.   Choosing a power connector is dictated by power requirements and compatibility.   The most common power connectors are XT-60, Deans Ultra Plugs and EC3 and EC5 Bullet Connectors.

I use the Deans Ultra connectors but I found they can lose contact when fully plugged in.  This is an inherent design flaw with the T type connector.  I would choose the XT-60 connector if I was not so invested in the Deans connector.  I favor the XT-60 because they are easier to solder and connect and disconnect with ease.
