A very nice breakfast was had at the Harvester Cafe in Spangle on New Year's Day. Afterwards about nine of us went to the Paradise field and flew for several hours. The temperature was about 27F. There was little to no wind, the sky was overcast, the ground was frozen and the runway clear of snow. With the right clothing, it was a nice day of flying.
The tie down anchors are going to be hard to install. I welded a lug nut on the end and got part way into the ground with my 1/2” driver before it stalled out. I think a 3/4” will work.
Does anyone have one?
Here’s what the anchors for the canopy look like:
If noone has a 3/4 impact driver I think one can be rented at Ato Z rental, or a home depot tool rental.
With the help of AI, I analyzed the canopy for a 60mph wind load and generated results for max rope tension and pipe buckling margins. Here is a screenshot of the recommended Home Depot hardware.
The analysis considers uplift and lateral wind loads.
This is the cost of a 20’ x 30’. Will have to check if a 10’ width will cover adequately.
There is an old lock on the chain in addition to the one we use. So there is confusion at times about which to use. (Sometime we'll have to get a portable grinder tool out there that can cut through its hardened steel). In the mean time David Duhaime said he will 'magic marker' the old lock to indicate it isn't the one to use.
