Making a Drone with Lego Motors and Propellers

Making a Drone with Lego Motors and Propellers

The motors, propellers and frame are made of Lego. Non-Lego parts are the battery, radio receiver and flight controller. After building I fly this quadcopter indoors and outdoors. Enjoy!

Drone specs:
Motors (4x): Lego L-motor [88003-1]
Propeller blades (8x): Lego Propeller 1 Blade 14L [89509]
Gearing: 1:1.67 gear-up for each rotor
Frame: Lego liftarms and other Lego parts (look at 11:41 component list)
Flight controller: Matek F411-mini
Motor driver circuit (4x): MOSFET IRLR2905 + Schottky diode 1N5819 + Resistor 12 kOhm (look at 03:57 circuit diagram)
Radio receiver: FrSky R-XSR Micro 2.4GHz
Radio transmitter: FrSky X-Lite 2.4GHz
Battery: LiPo 9s 33.3V 200 mAh (made out of nine Turnigy nano-tech 200mAh 3.7V 35-70C Pico)
Weight with battery: 410 grams
Max thrust: 470 grams
Flight time: about 2 minutes

    What if Lego starts making metal pieces……and he got a real battery………just what will this guy be capable of

  13. MSA Transportes Rápidos; Brasileiro com orgulho. on September 3, 2021 at 11:14 pm

    Vc precisa colocar um sistema pra manter o giro do motor. Igual a um manche de helicóptero.

    Pay attention to the 20 million views! 20 million. Not that the number of views in any way is a target – that is not the point. The point is that there has been a person sitting in front of a screen and deliberately watching this good video 20 million times. Its 12 minutes long. So in all, 4 million hours have been spent on watching this video. That resembles around 2,000 full man years of work.

    I hope that great outcomes come out of this!

    You are a really really smart guy. The way you explain the problems and solution tells me that you’re a true engineer. Your skill is unique
