At the last test, there was concern that the vertical test stand might not remain firmly tethered to the ground in a worst case scenario. In other words, the nylon guys might come loose. The picutes below are new high strength anchors.
Four (4) of these tie downs should easily keep an M motor or larger anchored to the ground. I cannot imagine the parts bending or breaking, and I think the red stakes will be remain firmly anchored.
Thanks to Edward at AlphaHybrids for the idea and pointer to StormForceTiedowns.com.
