View Full Version : Newbee, need help
I have been trying to adjust blade pitch. I have the swashplate level,and servo horns at 90. At 0% throttle, pitch is +1.5, at 50% throttle, pitch is +3.5 and at 100% throttle it is +9.5.
I can not get pitch set right. I want 0 pitch at 50% and +8 to +9 at 100%. What am I doing wrong?

First of all, which heli do you have? The remainder of my post assumes it's an eCCPM heli of some sort.
You mentioned the swash plate being level, but what about the mixer arms and blade grips? On a proper setup, the servo arms, swash, washout block mixer arms, seesaw mixer arms, and blade grips all have to be level at center stick and with the flybar held level. Another possible factor is the pitch curve in your transmitter: it needs to be 50% at center stick and, preferably, linear from 0-100 during setup.
Have you watched the Finless general setup videos, especially those dealing with CCPM setup?

The Heli ia a walkera dragonfly 60. It was a RTF, but I had noticed that the swashplate was uneven, so I made adjustments to swash links. Now I can only get +9 at full throttle, and +3.5 at 50% throttle and +1 or +2 at 0% throttle. And that is with the flybar level. If I adjust it down to get -pitch at 0% throttle, then my 100% throttle pitch will be lower as well. Do I need to take off the swatchplate links and start all over? I havent changed anything in the tx settings, and before all adjustments, I did have it to hover only about 2inches off ground, and it would start to move to one side and get the shakes. That is why I thought there may be a problem, and that is when I found the swashplate uneven.
Ok, I think that I have figured it out. There are links on top half of head to adjust and change blade pitch, and the whashplate movement will change blade pitch. So I need to take all link off the swashplate, and lower swash, and make adjustments on the top links,
right? :smokin: Im catching on, just take some time, but is'nt that the best way to learn! Just do it till you get it right!:lol:
