Cheap Tricopter Build and Stunt Demonstration

at 10:42 pm. Filed under Complex Hacks, Cool Gadgets, DIY Hacks, Electronic Hacks, Toy Hacks


Hallstudio has been flying RC planes since 1989, lots of things have changed since then. Check out this great Cheap Tricopter Build that he put together. It comprises of a bunch of inexpensive parts that total around $100 but give you the a great tricopter base that you can fly and modify. There are lots of interesting tricks that he demonstrates in the video such as the use of a drywall screw as a simply pivot point which allows a cheap $5 servo to move the tail rotor. If you want to build it he has provided a full list of all the parts needed in the comments of this video. Once you have the tricopter built you don’t want to be knocking into yourself or other things while you fly the thing. Check out the video below where Hallstudio demonstrates a simply but effective carbon fiber beach ball like cage that allows you to bump into things from all angles with no issues. I guess things like the AR Drone has similar crash resistant properties but there is something very cool seeing the flying sphere.

    Hello there,

    I need part list of the material used to build this tricopter.

    Thanks in advance

    Thank you for the design info – I am making this for a project. Please let me know how long the arms be – whether or not I can reduce them to 30cm. If not, please let me know what the minimum length can be – for the tricopter to efficiently function.
    Please let me know how you are doing the tricks. I have searched online but have not found any clear and easy instructions.

    Thank you

    Fascinating! The cage is the best idea in 4- 3-copters since the invention of the brushless DC motor! I was quite surprised to see them use an actual servo to control by tilting one rotor even though in theory I guess you could have controlled it by the thrust differential. I don’t know how much more difficult it would be to control by 3 motors thrust instead of more usual 4 but they took the risk of loading it up with the weight of the servo and in return got what looks like simpler controls. Very interesting and fresh design, I’ll be coming back to the video when I build my own. Great find, Alan!
