Here is the only link I can find to a Hirobo Shuttle ZX:[link]http://warhammer.mcc.virginia.edu/ty/heli/hirobo/shuttle/zxassy/zxassy.html[/link]
It is not the best in terms of quality and convienence but it is better than nothing.
Check out this site too if you haven't seen it yet.[link]http://www.raptortechnique.com[/link].It is good for an overview on setting up the heli even though it is dedicated to the Raptor, most of it applies to all helis in general.
If you can hover an electric well then you should have no problem hovering a nitro.I tried the new Protech Zoom 400 (awesome heli) the other day and it is quite similar to a nitro heli if not slighly more difficult.

Hope the manual helps!
