What is the best reactionless drive test?

I'm not going to ask you to be open about your project since you already made that clear by not saying anything at all. It seems to me you're looking for free advise for your own selfish needs. I encourage you to look at other on going OPEN projects where people are collaborating together and how much can be achieved that way. If you don't agree this forum is not the right place for you. People help and share here. We are beyond the point of making money, if we don't collaborate now for cheap global solution we will be doomed.

Maybe because there is no project? What makes you think I've even built anything 

I want to perfect a test, maybe we could even get some standard test that anyone could use on their device, as so far best anyone's said is "tie it to a string"

My bad then this just seemed like too much deja vu so I made a quick assumption. This is the thread I meant btw:

Reading that topic, it gives me an idea to how his problem can be solved, but I'm going to post it in this thread as I think it's more suitable here.

If we attach a long rigid rod to the top of the device, which points in the direction perpendicular to the direction of thrust of the device, and we tie two strings to each end of the rod, then that completely solves the problem that the guy is having. That should show whether there is thrust or not.

So basically there's a stick on the device that is tied to two strings on each end, meaning it makes it very difficult for it to spin.

But there's not enough information to conclude whether the test is sufficient. He hasn't ruled out other factors.
