MICRO FPV PROPS & BUZZERS

Micro FPV Drone propellers (props) come in many different sizes & shapes ranging from 40mm diameter to 4 inches. They also have varying degrees of "pitch" and numbers of blades. Your choice of maximum size is determined based on your frame's physical dimensions.

In the following video, I explain how your choice of prop size, pitch, and number of blades will affect whether or not you have longer flight times and smooth video.

I explore these parameters with 8 different configurations on the Diamondback Rattler Hybrid-X Micro FPV Frame! 7 parameters are captured during test flights for each of the 8 configurations, to include flight time and smooth HD video test!

My favorite "Go to" shops for Micro FPV props are AirBladeUAV, CycloneFPV, RaceDayQuads, and GetFPV and I normally use Gemfan or HQ Props.

Buzzers (or beepers) can help you with a number of things on your Micro FPV Drone. They'll warn you when you have a low battery, when there's an abnormal condition, and more. Most importantly for me, they'll help me locate my quadcopter should I have "inadvertently landed" in an unknown area.

Sure, you can set up your ESC's beacon to do the same thing and save some weight by NOT adding a buzzer. I've found a couple drawbacks to this method though. One, your ESC beacon isn't as loud as an externally mounted buzzer and, two it won't work if your LiPo battery has become disconnected from your quad!

So, with ALL of my Micro FPV Drone builds, I make sure to add an external buzzer. In fact, not just ANY buzzer, but one that is self-powered (has its own battery)! That way, even if my quadcopter's LiPo becomes disconnected, the self-powered buzzer will still sound off loudly!

I've tried several different makes and models of these type of buzzers and the ones below I have found to work nicely.
