Abiding by the Round Square theme “Environmentalism”, this year, CCH Aero-modelling Club made a “RC Sky Arrow Trainerโ aircraft model using 100% biodegradable EPP sheets.
However, their main project was the flying model of Soviet-era Mig-29 Multi Role Fighter Jet.
As a challenge, the Club also decided to construct a paper plane controlled by a smart phone.
