Hey,

I received my XII today & I really like it. :)

But my question is: I do not want to use the 64dp spur gears, but 48dp (have over 20 pinions in 48dp from my TC and don't want to buy new ones in 64dp).
Does Xray already offer such spur gears for 48dp pinions and if not which brand can I use (which fits the XII and the diff balls)?
(If anyone doesn't like another brand to be called here, please write a PM to me).

I need a fast answer please ! Thank you. :- )


Greetings,
Patrick

OK Dave,
so you are thinking the same like me. That means Kimbrough should be the right decision. :)

But another thing: How many teeth should I choose - 69, 72, 75...which one fits and is good to begin with?
Thanks!

My question again, please give me a short info:

depends on what motor wind you are running and the size of your tyres.

I'd suggest 69 for stock or 19T/10.5, and 72 for a lower wind as a start point

yep, the dust covers will fit. I have a set but don't use them anymore and they are a pain to fit and just add weight. My diff is built with only a smear of lube so nothing to attract muck.

@sorci: where can you buy those dust covers (maybe PM) ?

I searched them everywhere in the web but can't find them.

Thanks in advance ! :)

Those look like Kimbrough dust covers.
I once had a gift-certificate that I won at a race... I used it to buy a bunch of spur gears for my T2, and bought a bunch of those dust covers to fill up the value. (Then I bought a 007 and never used the gears :oops: )

hellow,

I drive a checkpoint 19T motor.

on a spur of 96 standart 64P. Would it be possible to use this spur? like with a 17T motor pinion? Our will i burn the motor on a ratio of 5,65?

Swords,

for 12th scale driving in Europe we use a different approach. Measure the tire diameter x TT x pinion / spur = mm per rev.

for a 19 turn motor like the checkpoint money motor start on a small track with 45 mm and for a large track with 52 mm

so with tires size 46.5 mm x 3.1416 x 30 / 96 = 45.65 mm

33 pinion will give a 50.21 mm ratio

35 pinion will give 53 mm ratio
