Well haven't got the bill from the machine shop for the new arms yet but it's gonna be stupid !!!
The idea was to eliminate the swash driver, lower the head, lower the use of the cyclic ring with extreme pitch ranges by decreasing the resolution slightly to achieve a value of 80 @ 8 degress in the Vbar setup and ended up with a value of 83 in the collective setup @ 14 degrees of collective pitch, without any binding of the elevator lever against the frame. It worked out perfectly, the head is in the standard Low Rider head position, ie:bottom 2 bolts in the head through the two holes in the main shaft. It looks like I could use the next hole down too but I have not tried yet.

The rigid Swash to Blade Grip links are from the Compass 7HV and the blue links are quick UK, but the Kasama ones are actually better shaped to avid conflict with the swash.

It has been a fun project so far and now I am just waiting for the new Scorpion ESC so I can fly it...

Just edited my post as I had written 14 degress of cyclic and should have written 14 degrees of collective !

Look out you don't get a patent case on your hand for this NICE work

Now THAT is what i've been looking for.
I need those arms!

Thanx!

seemore74 · 12-09-2011, 07:22 AM

That's the shizzle! So with that setup you get no movement on the links if you turn the swash back & forth?

pitch black · 12-09-2011, 11:03 AM

Hey Brett,

You might not be able to use the top most hole on the hub.
Seems like the clearance between the drive rods and the anti-rotation bracket is pretty darn close.
At your present mid-hole position, hows the gap at extreme pitch/collective inputs?

Thanx!

Ah Clem · 12-09-2011, 11:21 AM

Very cool!

Looking forward to your flight report, sir!

jamin_00 · 12-09-2011, 12:52 PM

Thats the mutts nuts

Kasama, take note

Brett74 · 12-10-2011, 12:39 PM

It clears, but only just if you use the top holes, i will make vid and show you, went and broke my ankle yesterday quite badly, will have to get some plates operated this week! Slowing the project down a bit....

Sorry to hear about your ankle, sir.

pitch black · 12-10-2011, 09:47 PM

Holy Moly.

That sounds awfully painful, I hope all is gonna be fine dude.

Brett74 · 12-11-2011, 07:02 AM

Yeah not really looking forward to getting the plates screwed into my bones, I recon it's gonna hurt! The upside is I get spend Xmas at home with my family, my girls are 3 and 6, I was supposed to be working offshore on a rig until the 26th Dec.

Well, better a broken ankle then. =p
Just kidding sir.

Thanx!

Brett74 · 12-18-2011, 03:16 PM

Hey guys, project has kinda dragged to a halt, I can't seem to keep my leg below my head for more than a few minutes without feeling like a large bear is biting the back of my calf, the wierd thing is that I have no injury there, all the surgery was around the ankle.
I have come up with a simpler way of making it so the costs will come down a bit.
I have to either learn to walk and drive with my leg on shoulder or wait until my leg recovers a bit more...will get to work on a video demonstrating the geometry.
Happy Holidays all...

pitch black · 12-18-2011, 08:07 PM

Kinda reminds me of the time i fractured my wrist. (Don't ask me how)
Bloated as a balloon.

Sounds like they beat the hell outa you while under ? hope it improves and you have a great xmas ... i'm interesed in this when you are happy to sell the bits-destroyed my lowrider head on the w/end

happy hols

Brett74 · 01-04-2012, 08:25 AM

Here is the video of the geometry in the VBar setup. Off course I meant elevator lever in the video.

pitch black · 01-04-2012, 09:22 AM

Sccchwwweettt.
I'm wondering if the new Align DFC arms and links can achieve the same perfection as your setup.
The bolts probably won't line up, but hopefully it has ample material to add another hole or slot the exisiting ones.

Brett74 · 01-04-2012, 09:31 AM

I think the new Align arms are asking for trouble, as the feathering shaft moves under load the links could be forced to pop off, there a very good reason Compass use the delrin rods....but we can always try..
