Wow, you have a lot of copter info on your link. I'll take some note of the blade examples you have. The front end approach is definitely common out there.
Yet the whole purpose of this heliocopter design is to conceal the blades going up. Yes, you're right, the blades on my diagram are not true looking. I think they're too thin and could use curvature/width etc. I may run into some roadblocks with them as the learning curve goes to work.
I've got till spring to mock up some parts and find my connections. I do have a good feeling about this one though (not in a cocky way), it's that rocket sense kicking in for once I guess.
I'll take some photos of this process as it becomes more of a reality.
Thanks for your input. greatly appreaciated.
