If you do get someone to make adjustments for you, make sure it is someone competent!!

I saw a guy trimming his new model (not a jet fortunately), which was proving almost unflyable, and asked for down elevator trim. The guy helping then moved the trim. The pilot lost control and it crashed. It turns out the helper was trimming down (i.e. up elevator). oops


If there are settings that need to be adjusted then I set them up as a mix on a switch or knob. This will prevent me from having to go into the menu (or pressing menu buttons). This is easy on the ZAP as all the switches are assignable.

I think your method would be ok but I probable wouldn't 'lock' the setting until on the ground after flight unless you can easily 'unlock' it again. I would also make sure that with the mix screen selected there are no buttons you could accidentally press that would ruin your day.
