So , you had both blade grip turnbuckles the same 21.5 mm length, but then you installed them and turned a turnbuckle a turn out and basically lengthened one. The blade grip arm where the two screws goes in, the mill is not deep enough. The arm can rock on the grip. If you are off, on turnbuckle length, loosen the two blade grip arm bolts and get the gauge to show zero and retighten the bolts. The machining needs help with XlPower. At the end of all of this, I would mount the blades and pull them to the side of the heli at center stick and verify both blades are even with each other to prove you are at zero degrees collective pitch. Now check positive and negative collective to verify the range is equal. If the range is not equal, check servo arm center, follower arms are level and the swash is level. Only other fix is to buy a SAB and the parts just fall together out of the box. This is a great heli after you figure out all of its quirks. I just wish we didn’t have to spend time checking that the head block is not rocked while assembling. The tolerances could be tighter on the bore for the head block to the main shaft too. There is always 50 ways to do something. Not knocking your talent, just adding to your knowledge. Sorry I’ll miss you at IRCHA.
Thanks for the reply, the purpose of the video was to demonstrate the head setup procedures for viewers and we wanted to show all the steps. The turnbuckles may not have been literally identical lengths. The heli flies smooth as silk without any special procedures.
Thats pretty much just a standard head build, great info but nothing special, if you really want to learn the PERFECT Rotor Head go and get Nick Maxwells video, then you will see what a PERFECT Rotor Head build really is.

Thanks guys! I’ve been building helis for 10 years and video is super informative!
Thank you 🙏, I'm glad you liked the video
Thanks Diego! This will be my new way to build up the head. My way was ok but this is even better. Thanks for sharing.
Great tips! I will for sure try that next. Thanks for sharing. Now on to the tail :)
Thanks so much, I have a full build video coming up
Thanks Diego for your great sharing
My pleasure 😊
This Align One way bearing tool is awesome ❤
Excellent video.
Thanks Dima
Couldn't have done it without your help 😊
love the Heli content!

Hi, Diego and Dim, is Jimmy Au here!
Hi Jimmy 👋
Hello. Do you have a video on aligning flybar blades and swash plate?
Great video guys, have kinda a newbie question, I’m always wondering how tight to run the blades.
6:40 I put just 1 millimeter at the tip and never had any problems
Would you please elaborate on how to get the servo horn at a perfect 90?
15:20 this assumes the work bench is perfectly level, and the helicopter skids, etc are perfectly level, correct?
Perfect 😂😂😂
