Frank, having had very few WASM crashes to date, I just had three in a row. All on the ground during the set-up process. I found the AIRAC had re-set to a previous one interestingly. i cleared WASM, Updated Nav, and re-callibrated the throttles (forgot to do that between crashes), and now all fixed and running. I thought it very odd to have WASMs as I have not had them for a long time. It's a very stable platform and I've been enjoying it right through the updates.
