RE: 3D capable SPAD w/ OS 40 LA????
Congratulations on getting your SPA3DT built and test flown!
But if "that F#$%^* cutting board motor mount" snapped, you most likely got the wrong type cutting board. And speaking from experience, plywood motor mounts break even easier.
Walmart sells two types of cutting boards that have nearly identical packaging. The only difference is that one says POLY in big letters, and the other one doesn't. If the cutting board package doesn't say POLY, or HDPE, then it's the wrong one and will easily break.
