Lego Compatible Servo for Lego Hobby RC Radio Control
How to use a Hobby RC transmitter and receiver with lego technic. Get more range, more power. You can't feel the controller when you use a phone but you can with a real radio. It works way better than other controllers. This is a two-channel setup but after you do this it is easy to upgrade to more channels or a more powerfull ESC. What to buy and how to hook it up.

One Lego IR receiver controlling 14 motors and a drill! Ever find yourself with limited power using Lego IR, SBrick or Buwizz? Use your control device to trigger a relay. Some people might be concerned with inducted current damaging the IR receiver but note that it is on a separate circuit from the motors and when the relay is not triggered the motors are not connected to anything. The relay acts as a switch and opens the circuit that the motors are on. There is no need for flyback diodes.

Johnny 5 leans into the corners to help stabilize the Lego motorcycle. This makes the Drift-Motorcycle 10 times better than it was in the last video. I just did a video about the drift cycle so In this one I spend more time blabbing about some details. Remote control using SBrick, one l-motor, and one servo motor. 3 one cell batteries wired in series give it about 12 volts.
If you like this don't forget to subscribe! Johnny 5 will be riding something much better soon!
