Interesting preliminary report and quite a few nuggets of information in there, thanks for posting it.
If I'm reading this right, the engine sprung an oil leak and the canopy was opened up possibly due to smoke in the cockpit? I only say that because one would assume that you could control the aircraft safely with oil coming up from the front of the canopy and opening the canopy would be of no benefit.
As for how a handheld radio and a flight bag both of a reasonable mass and weight could end up such a distance away from the crash site, did the aircraft roll inverted? It's a pity the other dynon wasn't logging.
