SPS, No, at the point where I have a tail blade where I want it, I stop to look at it and continue ....
Muff, don't know about "all the way tot he ground" though ... you only need to level the boom itself to take the sight glass reading, you'll go further to do your aft flex coupling check. I level the boom in prep for that, and verify oil level int he gearbox, then bring the boom down further for the coupling check.
You could consider the POH for a cessna, if I remember correctly (don't have it here to check) for the walkaround it has check flaps, but you learn from others to lower the flaps for the walkaround (and to check them)
For that matter, when first learning the Robbie preflight, my orig manual has notes onthe pre-flight, such as noting the number of nuts on the coupling (duh) and even better it has the teletemps check (Main gearbox area and upper and lower bearing, and on some the driveshaft from clutch to main tranny), but doesn't specifically tell you in the POH how many you are checking ....
