According to Flyer website:
"Skyports is seeking a Temporary Danger Area (TDA) complex to be established during notified periods to enable the safe testing and demonstration of unmanned aircraft operations during a trial for up to 5 weeks starting on 8 April 2021. The TDAs will operate from the surface to various heights up to 950ft amsl."
Looks a bit too close to the Glenforsa circuit to me especially if it is up to that height near there. And starting just when the weather usually starts to improve for GA!
Will probably know more once I have watched the Flyer livestream featuring Brendan Walsh.
