I've purchased an RCA 407. It came with a Tarot ZYX 3 axis gyro and I'm using a spektrum DX 7. I've completed the software setup and mechanical setup. My colletive pithc is at -6, 0 and +10. They want the the pitch @ -2 at lower-stick, +5 at mid-stick and + 10 at the upper.
My question is what do I use to get that? This is my first fbl gyro. Do I use the software, radio pitch curve or set it mechanically? I've tried moving the points in the radio pitch curve but that did not work. I did not see anything in the software except adjusting pitch to change collictive travel.
I did have it setup mechanically, lower stick was -1 and servo arms were 90 degrees, mid stick was +5 an the top was +10, I was advised not to do this because I would confuse the gyro.

RAC 407 collective pitch curve

Thanks Jose! I did replay to your post on helifreak. The radio pitch curve menu did not change the pitch. I'll try what Cap suggested and use the advanced menu in the software.
The kit does comes with scale blades. My friend also has one and -6 at low stick is too much, he had a hard landing on his test hop.
If anyone has a Tarot and having problems, the youtube videos "HK 450 FBL conversion pert 4 and 5" are great training aids for setting this gyro up. Just wish he would have done a "what if pitch curve adjustment". I think he did a great job
Again THANKS for your input.
