Construction of the Bumble Bee

My son Matthew said that he would like to build a radio controlled air plane by his own. From the following requirements this model came out:

  • Motor modell
  • Simple to build
  • Simple to fly
  • Low wing or mid-wing air plane
  • Nice to appearance
  • Pilot!

Some little corrections have to be done still. Then the training can start. The flight characteristics match the expectations.
