Mini Joker on 6S

[surfanarchist]

I'm looking for some information on a 6S power set up on a mini joker. Now with a motor in the 1000/v range how do you match the motor to the main gear to achieve a given head speed, say 1800 - 1900 RPMs? I plan on using a Neu 1910H/1Y motor which is a 1050 kvh motor. What would the stock 14 t pinion give me with this set up (running 6S)? Since the joker series uses a belt between the pinion and the main gear can one still use a simple head speed calculator to estimate headspeed? As you can tell I know very little about jokers but I like what I hear about the quality and all the CNC parts so I'm really considering getting one.
