As Brian implied, it would be very difficult, even impossible, to create a 2-bladed autogyro teeter rotor that didn’t have design features “borrowed from others”. I’d even say that it would be pretty stupid not to look at what others had done and “borrow” the best parts that had been proven over time.
You also reply that:
To control costs, I feel that it is not necessary to include features that the vast majority of the customers will never use.
Yet you include a more expensive and complicated system for tracking, I could ask how many customers will know how to track your rotors?.
It’s clear that you want to be the “original thinker” and that my posts annoy you so from now on I’ll leave you (and everyone else on this forum) alone. This thread reminds me of the reason I stopped posting on this forum a year or two ago when I wrote
“You can lead a donkey to water but you can’t make him drink”.
Nothing has changed.

A small correction, AutoGyro copied the ELA (some say they even got a copy of all the drawings) and contrary to what many say, ELA didn’t copy the Magni, they introduced a number of new features and ideas (not all good in my opinion but they were at least different) and many of these features have been carried over into other makes.

AutoGyro rotor heads were identical to ELA (because they were copied), they have some different features now. The Magni solution is the one they purchased from Tervamaki (as Brian says). The original Tervamaki design didn’t have a chordwise or tracking adjustment and I believe the very early Magnis didn’t either. I had one of the early M16s and that had the chordwise adjustment screw that was designed and developed by Magni not me. Since September 2018 Magni rotors have a tracking adjustment feature and I was involved in the design of that.

Thanks for the confidence; as I said last year, it’s a waste of time posting here. You have my number if you need me.

Mike,
Don't know if you will see this post, as you seem to have implied that you will no longer be visiting this forum.
If you do see this, and to everyone else, I'm sorry if you feel this escalated in tension. I was not at all annoyed with your posts. I thank you for your input!
It just seemed strange to me that an earlier post started out with
" if you got the idea from him it would be nice to give him a credit"
and then your next post starting with
"Your teeter block looks to be inspired by AutoGyro".
Of course we all borrow design ideas everywhere we look! Myself included! It just took me by surprise because I was honestly not aware of the 2 examples that were in discussion.
Again, I apologize if I came across as being upset.
To clarify my position on blade adjustments.
Static balance of the system: VERY important! (my design allows for the placement of tip weight additions)
Tracking: Very Important! I hope my design (which apparently I wasn't the first to conceptualize) makes for very easy precise adjustments.
Yes, I am confident that ALL of my customers will know how to track the rotors since it will be provided with the documentation.
Once I get some more testing completed, I will be able to include in the instructions a very simple table stating: If your "x" blade is tracking 1" high, then go to the setscrew marked with the X and give it a 45° turn clockwise. (Or whatever that value turns out to be...)
Chordwise adjustment: The finest adjustment you can make, and important if you want the absolute smoothest system possible. (Which I would, but I don't feel every one want to go to those lengths.)
I'm just willing to bet that the vast majority of people flying a Benson, Brock, Hornet, Gyrobee, Air Command, Dominator and what-else have never performed any chord-wise balancing actions. I'm sure some, but not many.
If this turns out to be a higher demand than I am currently picturing, then by all means, I will add that addition to the design.
But again, in its simplest form, a couple shims would take care of this.
As for the tracking adjustment, I don't feel that the addition of the 2 set screws is all that expensive or complicated.
On another note...
The Razor blades saw their first air on Thursday!
I only had time for 2 low passed down the runway, but everything felt very smooth, solid and promising!
Can't wait for more testing after Mentone!
