I like the remote NV.

BTW, only the larger AX series engines have the angled valve. The 46, for instance, doesn't.

I've never had a serious prop/finger colocation , but I've had my nuckle buzzed by a Norvel .061 turning 21Krpm a couple times. The NV on this engine is about half an inch behind the prop. Not even a broken piece of skin, but wakes you up anyway.

The idle is best set with the engine stopped, in small increments. You can't really set the idle by ear like the HS needle anyway, as the changes take too long to take effect at idle. Run, evaluate, shutdown, adjust, run, evaluate, wash, rinse, repeat....
