Thanks to HQ Props for sending me a huge box of props, so I get to try some of their best mini quad propellers. It’s going to take me a while to go through all of them, but I want to test them thoroughly and do my best to comment on which one I like the most and why.
What is PoPo Quick Swap System? PoPo stands for Pop On Pop Off. The PoPo Quick Swap System is a motor shaft design that aims to make changing out propellers faster and more efficient.
This tutorial explains the basics of mini quad motor: the construction, design features and other factors that can affect the performance and efficiency of a motor. This will help you choose the optimal and effective motor for your next quadcopter and racing drone build.
Azure Power sent me some new crazy-looking 5″ mini quad propellers to test. These props are designed for racing and freestyle flying.
This article explains the basics of propeller (props) for quadcopters. We go over the concepts of pitch, shape, difference in the number of blades and how these affect thrust, efficiency and performance.
I received some propellers to try out from DYS and Xperdrone (Hobby Cross). They have various sizes: 3 inch, 4 inch, 5 inch and 6 inch. I ran some thrust test on them comparing to HQ and Gemfan props of the same size, and also see how well they perform in real flights and how crash resistant they are.
Today I finally had the chance to test the famous HQ5040 props on my mini quad. Having compared the Gemfan 5030 with the HQ5030, I liked the Gemfan 5030 better because it’s cheap and generates more thrust. I also like the HQ5030 propellers for the quality and stiffness, but I would love to get more lift out of these props. HQ5040 could be the answer, as it can generate even more thrust than the Gemfan 5030 props (according to the datasheet of the motors I use).
I have recently had some experience mounting the hobbyking 5030 propellers on the prop savers that comes with the 2mm shaft micro motors (e.g. hextronic 1811 2000kv or the Turnigy 1811 2900kv) on my micro quadcopter. A lot of people complain about the likelihood of the o-ring get loose and the propeller drops, causing a aircraft crash. Not only you might lose the o-ring and propeller (it could fly away anywhere!), the crash could damage the plane.
