Here is an easy to use head speed calculator for the Hurricane 425 and 550.
Edit: Link no longer functional.
EDIT: Most of these great head speed calculators no longer seem to be available for whatever reason. The xls file on the last post submitted by Vas works really well. I use it all the time.

honestly... that head speed calc is not bad... BUT.. it does require having an internet connection... I'll host the stand alone one I use and link it to here.. using a head speed calc is a great way to determine gearing options to get the most out of your motor and heli...

Just to let you guys know. I downloaded the above head speed calculator onto a flash drive and scanned it with 2 different anti virus programs, and 2 different anti mailware programs. No threats were found with any of them, so I ran it to see what it was.
Actually, it is probably the best Gaui 425/550 head speed calculator that I have used. It has no pre-set check boxes like the others do. You put in whatever values you want, even an 18T pinion if you like.
Tokugawa, sorry for all the fuss over the links you posted, but, we like to be cautious when it comes to things like this. Never know what kind of things people will post on sites like this.

+1! That's a great program, Tokugawa! I just tried it out, too! My only question is this... What's used as the voltage calculation for a 6S battery? I'm asking because if it's 22.2 volts, that would produce the absolute minimum headspeed one could expect with a set of gears... Which is probably a good thing, but I'd just like to know. Thanks!
Sorry for all the fuss.

here's one a mate did up for me. All the different gear sizes have drop downs with hopefully all scenarios. All boxes are variable, just type in your required numbers in them...ie motor kv, efficiency,batt voltages etc etc Have a happy and safe new year all Vas Attachments:
