Obviously you are not joking but I have a question? Are you more (in)competent missing something from a written checklist or one from memory? And with a very simple and old aircraft such as a Moth, who should write the checklist? So called experts or people with real experience who have flown hundreds of hours in the things? Also, I'll suggest that around the world most simple piston engined flying is done without written checklists. Such things are replaced by simple mnemonics and apply to virtually every simple piston aircraft from Moths to twins with wobbly props and retractrable gear. There has to be a reason for that, but each to their own. But for aircraft like Moths with open cockpits and open control runs I really do not like the idea of a lump of card, paper or plastic being loose.
Returning to this prang, what I can't understand is how a wrongly set trim caused such a kerfuffle. The trim on a Moth is not that powerful and is easy overridden. Something else happened here.
