Learning from attempts.. This INDIGO flight is based on differential thrust, with the body length of 4ft and wingspan 3.8 ft. Power is provided by 3S Li-po battery and 2200kv BLDC. During its flight an ESC wasn`t working efficiently, as a result it got crashed. { Unfortunately it couldn`t be repaired as it`s made of thermocol :( } But as it is said that "Success is not final, failure is not fatal. It`s the courage to continue that counts." We will try to make more improvements and are soon coming with a new projct :)
