5 of em are out there, all of em are still kickin as far as I know. 4 in the US and 1 in France. I tried to break it and I never had a problem. The weak point is the brace to tower mount, thats the only part I have ever seen break. Its an easy fix, so it isnt catastrophic by any means. The cast plastic ones were the weakest(most were cast), I ran billet plastic on mine and they were unstoppable. Its perfect for the HV plans you have, with room to spare. I will email the files to ya asap.
