Alan you have some serious hold-downs there!

My father-in-law is a German  structural engineer. He calculated we needed 24 tonnes of ballast to hold the structure secure to a sub-cyclonic wind speed. That's 24 tonnes there but the reality is the fabric would give way long before the blocks shifted! Our bird flies south if big winds are expected -and we live outside of the cyclonic zone.

Looks nice.  Re pump I made up a 12 volt one using the red 'AreoFlow' 97 GPH pump  works a treat off either the aircraft battery or my hangar spare on a trolley.  Cheers

Good idea. I've admired systems like you describe but to be honest I'm a bit wary of an electric fuel  pump owing to fire hazards. I'm out the back of beyond and in the dry season this whole district is a tinderbox waiting for a spark.

 

The  high ambient temperatures  here makes batteries temperamental. I'll stick with a basic hand pump for now.
