Here's an update to my 2014 video about RC equipment for rubber powered airplanes. Although some products have gone out of production, I was happy to find that there are still several light receivers and servos that are readily available. Note: I say g/cm a few times for the torque, but I mean kg/cm throughout (I get it right later in the video!). Get a rudder on your fin (I like rudder-only for rubber power), get a receiver, servo, and battery (and transmitter if you're just starting), and get out and fly!
Here are the websites mentioned in the video:
