Ok as no one seems to know the answer to my last thread can someone just tell me if both main blades need to be in sync right through the pitch range ? and if not what will be the outcome ....thx

if both are not showing the same pitch your blade tracking will be out

Set it up on the bench first checking 0 pitch at mid stick on both grips/blades. Then spool up at the field and watch to see if both blades are in track. If they're not. Mark one blade grip, I use a spot of Tipex. Adjust only this blade one way or the other. A full turn. Spool up again and see if it's better or worse, if worse go 2 turns in the opposeite direction, if better there you go

Hello mate
provided your swash is level throughout it's travel, your TX is not (very) important for setting blade pitch.
First off, get the servos as close to 90 degrees as possible at mid stick in idle up.
Get all of the servo to swash links the same length.
Check the swash is level throughout its travel, preferably with a swash level tool.
At mid stick, with a level swash, set the links from swash to washout so the washout arms are horizontal.
Set the links from the washout arms to the flybar cage, so the cage is horizontal, and therefore the paddles are horizontal - 0 pitch
Set the links from swash to seesaw arms so the arms are horizontal, cage should be horizontal all around.
Set top links to same length as each other, and correct length to get 0 pitch on blades.
Assuming all of those are done, everything is level and equal, you should, in theory, have 0 pitch and equal pitch. If 1 blade is out then use the top links in small increments to adjust, but only adjust 1 blade, keep one as the reference.Trex 600 ESP (Turnigy T600, DS821, DS620, GP750, 120A) sold

Okay, it looks like your not setting the head up from scratch as PaulSouthport explains above.
last night while resetting pitch to factory settings on my t3ds i noticed that after i had set pitch up on one blade -3 / 7 /+11 the other side was not symetrical -7 / 0 / + 7 . and the only way i could get them any where near the same was to alter the mixing arm on the second blade which resulted in blade 1 being -3 / +5 / +11 and blade 2 being -3 / +4 / +10 . now i know i dont have the best TX in the world ( WFLY FT06-C) but are both blades supposed to be the same pitch right through ? and the way my TX alters pitch is via a dial that says PZT but there is another dial next to it that says PLZ that doesnt seem to do anything that i can see .also iv just fitted new main/spindel shafts and flybar so i know its not them throwing it out .
That's your other post. Forget about the Tx, it can't influence one blade over the other. You need to set your links symmetrically and the same as each other. What heli is it?

If you set the links to the right length you will be ok unless something is damaged. You do have to get the lengths very accurate to 0.1mm. You'll need a vernier for this. The main thing is that there are (not two) but three pairs of links. One short pair and two long pairs. Each pair needs to be the same length. On some heads these links are fixed like the top two short ones on the Trex 450 Sport. The other three links are for the servos and just need to be adjusted to get the swash level, with the servo arms at 90 degrees to the links for centre aileron, elevator and pitch. The pitch settings need to be checked with the flybar level. You must also check that the swash stays level from full negative to full positive cyclic. This should be ok if the same throws are used on each servo and the same arm length.
On some helis, like the Blade 400 and the Twister Storm one of the servos is set to a different arm length and a different setting is used in the Swash Mix.Flasher 450 Sport. Assan GA250 with 520 tail servo, MKS DS450 cyclic.

ok i have followed all input to the letter , leveled swash corectly and set all links using a vernier and set up servos at 90 degrees at half stick etc etc but one problem still remains . when i apply throttle and check swash level it differs from -10 to +10 and visually i can see that the swash falls slightly on one side when going through its full travel , so if i set up swash level at full stick for instance by the time i get to half stick there is a gap (about paper thickness) at one side .....hellllllllllllllllllllllp plsTwister 3d storm
