Flying Project

I could be wrong here, but I don't think the rotors opposing directions will negate the torque vectors to the point it will be easier to bump the gyros out of plane. The reason airplane engines are canted at 10 degrees off center is due to the torque vector, but that doesn't eliminate the the gyroscopic precession - it merely prevents it from having as large an impact on the aircraft's tendency to yaw because of it.

A way to find out your chances, would be to look up a twin opposing prop airplane and see if the engine is mounted in line with center or skewed. If it's in line, you're in luck. If it's canted, you're probably screwed (or at least going to have a lot of physical effort to fly your machine).

now I thougth I had seen it all.

Well now that the weather is warming up some I thought it's time to do more
testing with the heli project. I uploaded 2 new videos of running up the engine
and drive train with all 4 rotors installed. I still have a lot to figure out. This is for the ones that requested updates on my progress.

I will echo earlier comments and say that is one of the craziest things I've seen on this board. I see you wear a lot of different hats, I didn't think Test Pilot was one of them. Please stay safe.

Nick,
Thanks for the videos, they are great. So what is the next test? Did you notice much lift during your test? How much throttle did you use? Keep it up and good luck.

Nick,
Can I put a life insurance policy on you? It might pay well with that contraption!!!!
One thing I would do is put a shield on the drive shaft if I was you. You have a lot of trust in your work.

One of the biggest issues I see is it will not be instinctive to fly with the control system that you are using. Push left to go right, pull back to go forward.
A very ambitious project. Be careful.

Pretty much the same as flying a hang glider. Or, guiding an auto by grasping the steering wheel below center.

It's intuitive, once you're airborne.

The rotors are at 0 degree pitch now so no lifting. I am in the process of making 8 degree wedge shims to give the rotors positive pitch. It's a starting point and I'll see what happens. Btw...so far throttle has been on the low side.

Just wanted to reiiterate (sp?) on what I told you before and what others have said: BE CAREFUL!!! We'd hate to lose you........
