I also forgot to mention the possibility of making a build class where kits are included. If we were to do this model it will likely have a longer ramp-up time to coordinate RSVP, ordering of supplies, waiting for shipping, and finally the class itself. There would also have to be a few different prices based on what people already have. Something like:
Airframe only (laser-cut DTFB) - $10
Receiver-ready kit (laser-cut DTFB, motor/s, ESC/s, extensions, servos, push-rods) - $75
Starter-kit (laser-cut DTFB, motor/s, ESC/s, extensions, servos, push-rods, transmitter, reciever, battery, charger) - $150
Just to be clear, these prices are totally made up, I just used them as examples!
