K'Nex gears and DIY Throttle

Hello and nice to meet you in this wonderful forum...
Guys i have bought all the gears from the K'nex site
K'NEX User Group - Gears
and i try to make a throttle with two levers for a twin engine aeroplane...
a bought a couple of 10K pots (A) (i think this is the linear and not the B logarithmic) and some 6mm rods cause the gears have a hole for 6mm shaft and the pots's shaft is also 6mm.
i used the gray 14teeth gear for the pot and the 34 teeth gear for the rod that it is moving with the throttle.
First i want you to tell me if there is another gear with more than 34 teeth but as the K'nex to use it with the gray one,
cause now with the 14teeth and 34teeth the lever have to make almost 120 degree circle which i dont like it...i prefer to make a 60 degree...So i want the relation of the teeth gear to be almost 1:5.
Second i want you to help me mount all these together cause i think i am doing something wrong...
In a while i will upload a pic from my cellphone to understand what i did...
thanks in advance
