By the way since Mel is in the topic, if someone decided to do this (I don't recommend), how would it play with FAA rules?

There are no limitations by the FAA for such testing that I'm aware of.

However, PRUDENCE should be a very high priority here.

It would be simple to safety wire the flap to structure inside the RV-8 once you removed the linkage. And the standard flap actuation system doesn't have “stops” - its just analog as long as you hold the switch. If you have an aftermarket system that goes all the way to a preset position with each switch toggle, and it couldn’t be defeated, I wouldn’t even attempt this test.

I have Garmin and it can be programmed so that it only goes to say 10 degrees and doesn't go past that, that's what I meant.

Although if any electrical system decides to get stuck and lower flaps all the way down during this, it's not going to be good news.

You see - now you’re thinking like a flight test safety analyst! That’s what anyone should be doing for any test they plan to do with specific equipment included.

BTW - the operational control for a “flap switch stuck down” in most ordinary configurations is to pull the breaker, so you’d flag that breaker in advance. It’s all in the planning.....
