With so many propeller options out there it’s hard to know what you should use.
- What length of propeller should you use?
- What does the pitch mean?
- What’s up with the three and four bladed propellers?
- What is a bullnose propeller?
We want to make it all a bit easier to understand.
What length of propeller should you use?
Once you know what size propellers you frame allows, you may have a few options depending on the motors you have or plan to use.
The length of the prop determines the speed it needs to rotate in-order to generate thrust. Larger propellers can be more efficient but may require different motors.
Many motor manufacturers provide thrust charts for their motors and these can be used to find an ideal motor and propeller for your system and style.
Actual thrust numbers will vary as there are many variables in play when testing thrust.
