RE: Stepping into nitro helis (Shuttle)
Happy Late Thanksgiving Dart,
I have to take a look at my ZX and see what I did for that setup. The Quick UK head gives more travel with better clearance between the lower washout arms and the pitch links at full negative pitch.
I know if you use the stock link lengths given in the manual you'll find the mixing arms are not level at 0 pitch. Its simple to adjust the arms from the paddle bar input links to level the lower mixing arms, just make sure they are the same lenght. I always go equal turns on each link when I adjust and things stay together that way.
Level the upper mixing arm the same way and you should have a nice starting point. I think my ZX is running +10 0 -8 in idle 2 and +10 0 -4 in normal and idle 1 but I have to check. The Plus is at +12 0 -10 with the Quick UK parts and the OS .37 pulls that quite nicely.
I really dont like the fixed pitch links below the swash plate but I've been able to make things work okay with them.
