Multicopter Design Lessons

Here's an area where you can ask any kind of question about RC models and find a whole lot of useful information to help you get started.

Multicopter Design Lessons

Postby jax200 » Sun Sep 03, 2017 12:53 am


I'm fairly new to the RC world of multicopters, and have now spent a good deal of time viewing your videos. Many thanks for all the energy you put into this endeavor, particularly with the didactic stuff and build tips that are so important to understanding the basic concepts and make us better builders and pilots.

That said, I am very keen on learning more on how to design multicopters of various configurations and missions. Currently I am looking to design two types of 1000mm hexacopters: one for endurance and payload (cost not as important), the other for speed (but cost low as possible). I am using ecalc as a guide, but quite frankly I am not entirely clear as to the design algorithm to use. Have you addressed this in any of your videos?

For example, with the second type "race" hex, I started with the following assumptions: size: 1000mm, weight: 2.5kg, endurance > 15min, speed: as fast as possible (I'm up to > 35 mph now on ecalc). I played around with props 12-15" with different pitch. Tried different batteries to satisfy endurance and power demands. For the motors, I started with some Multistar 600 KV. How do I go about optimizing the design from this point?

What is your suggestion for a non-engineer, new builder who wants to learn more about design? Have you published any books on design?

Again thanks for your very informative videos.
