Default DFC head adjustment??????
I just got a DFC head to go fbl.
I have 2 much positive pitch at Zero throttle (7/8 deg)
I can adjust the swash linkage to the servos but that's a Lot of adjusting.
How do you adjust a DFC or can you.
Thanks,
Roger

I believe adjusting the swash linkages is about the only way. My swash linkages are shortened on my 500E fbl. You're right it is a pain, but you only have to do it once.

Default Thanks guys
Maybe I'll just set this aside and buy a normal FBL head>
What is the point of a DFC other than doing away with a 4 ball swash?

  • Lower CG
  • I think DFC like higher head speed
  • Less parts replacement on crash

Here's my Tracx/Compass 500 setup. It's its own version of DFC. DFC basically means no swash driver or washout arms. Less moving parts and less mass. Super easy to setup and maintain.
