Perhaps members of this forum would be willing to donate some items to your cause? I have had RCers donate pieces and parts so I could build a demo RC plane that I used at airshows to show kids how to fly. It was a static model but I had servos, a radio and receiver and batteries donated. What do you say guys, can we help these kids out?
Also, cht212 check with local clubs to see if they can help you too. If you are wanting to fly an RCplane you will need instruction.
