Scale-Helicopters with electric sound

  • There are more and more LiPo-Flyers with their Scale-Helicopters on the airfields.
    Would IPACS please check the possibilities to offer the Scale-Helicopters standardized with the option to choose them as electric-variants (with electric sound)?
    For example some actual Helos: Guimbal G-2, EC-145T2, Bell 505, Bell 412EPI, AW 119, AW 109
