Hears how I do a setup of a heli head for 0 pitch, middle stick.
This has worked for me many times.
First, I set my swash level, with all servo arms at 90deg to the Mainshaft, adjust servo/swash links for a level swash, install the head and head links, if your head has a swash follower, put its links at 90deg. also, adjust swash height as needed.
Check levelness again after, I also move the swash to the higher and lower pitch heights to check for any unwanted movements between these 2 points, if all is good here, install the head.
Put cyc.pitch stick in the middle stick position, the fun starts here.
Put on your pitch links, and use a screwdriver, or anything with a 3mm straight shaft, and put it through your bladegrip blade screw hole.

Adjust your pitch links so the screwdriver shaft is inline with your mainshaft, your done.
Adjust your end points for equal pitch in both directions, Go hover, and check blade tracking, I have never had to adjust blade tracking using this method. Was always dead on, but different blades may cause it to be off a bit.

Fresh from the laser table,
Trex 450 Sport Frame Plates.
Made from Grade 2 Titanium. The DXF I made myself, without the oval holes for a better look.
I flew with the carbon frame plates, crashed, and had to buy new ones, flew again, and was buying new ones again, I got tired of buying, so I made some from Aluminium, crash, and straighten, ok, I had to rebuild anyway, but saved the price of the framing.
Got better at flying, noticed the Aluminium frames were flexing under load, and sometimes stayed bent, Hmmm , what do I do there, Tried SS and was to heavy,
Titanium came to mind, 1mm, 1.2mm, 1.5mm.
So I made some frames from Ti, and am on testing them out at this time.
Looks good so far. No flexing so far as I can see, The 1mm top frame is strong enough for the massive pitch pumps (12+ 12-) from 40ft. 3800 rpms.
Crash tests are coming tomorrow.

Was putting it together today, almost finished.

My dream is to build a heli for beginners and Pros alike, same bird, just a different pilot. Durable Heli for a beginner, takes the goof ups better.
You add your favorite electronics, and up ya go.

Well, I was at it again, I made some main and tail shafts from steel stamping rods,
Yes, the very hard rods that you punch holes in steel with, Drilling was a PITA, none the less ,I accomplished it. I just dare someone to bend 1.
I haven't managed to yet, and after 30 crashes, its still on my heli. Straight as an arrow. (I used a press, and bent one 8mm in the middle, and it went back to straight , try that with a steel 1)

I will be putting them on the market sometime, would be about 16$ a Mainshaft
(tailshafts come for free) Buy a main, and get a tailshaft for free.

I test all my parts , before they go out, so you wont have to worry about the craftsmanship afterwards. Good comes to you, bad goes in the trash...

Well
Ive been at it again, was foolin around with making some stuff, and found some old cabins from a 350 size heli, narrower as a 450 size heli, so lo and behold I tried 1 on my f-45, cut to fit ,the width was perfect, mounted it and looks like a big boy 450. Lucked out on the size.
Look for yourself at the pic I think, but than ya know , who the f..k am I anyway lol.

Looks like I found the right scale for this bird.

Well I guesse I have to put something in here,
1st pic is of my center of gravity stand,
I made it from aluminium, cut it and whipped it together,

The top boom is adjustable, has hole for (I use fishing line) wire, on the end of the line I used a m5 screw with a 1mm hole through the middle,
Cut a thread in the mainshaft for the screw, simple but works and looks good 2.
When helis a swingin on the string, you can turn it around to see and measure
your C/G. (crooked or tilting) and add weights or remove to get it evened out.
I will be posting more stuff as I work on it.
