I have a Sceadu 50 with a Hatori 60, Just picked up a GV-1, The first thing I did with my pitch was set the radio 9chp curves at 0,25,50,75,100%
Then set the mecanical linkage at top end +11 center 0 low end -11. then when that was set I went back into my radio and set the curves for each condition. Normal mode was set for -6, -3, 0, +5, +10 (You can tame this to your liking for hovering practace less neg is a good thing when starting out) Idol 1 same pitch as normal, Idolup 2 is set for -10, -5, 0, +5, +10 Thro hold is set for -11 -5 0 +5 +11. Thro setup is 17% 26% 35% 65% 95% Norm mode Idol 1 65% 50% 35% 65% 95% Idl2 95% 65% 35% 65% 95% My head speed stays steady at all modes and flys like a bat out of hell lots of fun. Sceadu's Rock hope this helps
