Different pitch reading, but tracking perfect

[sLapshock]

Hi, on my idle up mode, my tracking read

blade 1: -12, 0, 10
blade 2: -14, -1, 10

but my blade tracking is perfect, will tis affect my flying?

If your EPA (end pt swash levelling) is set correctly, max pitch up and down, heli climbs and sink vertically without undue variations, it wont hurt you much.

Even with perfect tracking and the swash is not levelled at max +ve and -ve pitch, it'll give you problem.

Unless you are using FBL, then end pt levelling is said to be inconsequential.

im not using any EPA, all is 100%

with that kind of pitch (i just CANT GET PERFECT -10, 0, 10) FOR both blades...

is it affect the flying greatly?

Middle of blade 2 is -1, that means you still can tweak the linkages.

Hi bro,

I would suggest you re-set all your EPA, SWASH MIX and any electromechanical setting to default.. and start from scratch again..

presuming you have all your servo 90 degree.. and you have same servo horn and same servo horn Hole..

If both blade doesn't travel the same.. It only means a few things..

1. diff servo horn hole.. travel on your servo will be diff even if you never adjust EPA,,
2. swash not level.. mechanical set up is not accurate..

from what you mention, one blade travel more than the other sound more like control rod is not balance..

I'm also presuming that you don't have any bend main shaft and feathering shaft..

go thru all that i mention... you should be able to find your culprit..

cheers..

isn't this hobby fun and frustrating..

i checked, actually everything was good, i can fly it without any problem..but im kinda felt uneasy knowing the pitch are like tht.

if i adjust the linkage to fix the pitch reading, my tracking would be off right?

your tracking would not be off if you do everything right..

the reason for you to post is.. you already find that something is not right.. right..

definitely something is not right when you have both blade with different pitch.. right...

so my advice is don't just change the length of one side of the blade..

start from your servo up.. that way.. you'll find the real culprit..

is it possible for you to tell me which part should i check? because i find nothing wrong on my head setup, just that my pitch is different reading. even my tracking are perfect.

[remotemadness]

like i said..

you got to start from your servo up.. the 3 servo to swash rod.. level your swash at mid stick.. then work your way up.. working as a set.. all rods from swash up should be same length..

refer to your manual.. it should tell you all the length needed for each sets..

[hallobaby]

i believe not your sevos and mechanical set up
its the blade you using....
the weight of your blade is different...
or
the CG of your blade is different....

i also have these issues when im using cheapo carbon blades..

Can I find out if the see-saw portion must be also level at mid-stick in addition to swash plate being level from all angles of view? I found that at the lowest stick pt, the see-saw gets tilted upwards. At max throttle pt, the see-saw and swash plate is level. Is that anything wrong?

Yes.. at mid stick everything must be level as well.. and blade must be "0" degree.. then both max positive stick and negative stick should give you same pitch.. If not then your servo arm is not 90 degree to servo.. that's why you must start from servo up...

1. servo arm 90
2. servo rod same length(depends if the servo is all in the same position)
3. swash plate level
4. adjust rod so that seesaw level
5. adjust rod so that flybar cage level
6. Pitch rod same length..

I think this is the sequence.. correct me if i'm wrong..

If servo is 90 and you are not getting equal pitch on both "+" and "-" pitch due to hitting the head block or swash.. then you have to adjust servo length again.. and start all the above all over again.. it either means that the 3 servo rod is too long or too short to start with..

hope this is clear..

Sorry but I understand some of what you're saying but I'm getting the pitch ok -11deg at lowest, 0 deg at midstick and +11deg at max throttle. Just that flybar cage or see saw thingy not level at lowest stick pt, still NOT ok?

sorry I don't understand your problem.. I don't have a heli with me.. so I'm not sure if that is ok..
