We went to Menuma Gliding Field at 5am on Sunday, June 26th. It was a clear, refreshing day in between the rainy season. With the cooperation of the Aoyama Gakuin University Aviation Club, we tested the installation of the prototype WAZA Cover for the ASK21. [The photo shows the existing cover.] We will keep the technical information secret for a while, but we are planning to show it to everyone at the "Harada Kakuichiro Cup (University Gliding Competition)" to be held in August.Please look forward to it!
