Pinion for DB01 with 12*2 motor?
 

Hi all,

Has just built my DB01 (Durga), and have fitted a oldish T.Q. Motor 12*2t that I had come over rather cheap.

My main vorries are the desition of pinion to use to not overload the motor... :confused:

In Oople's review he used a 21t pinion with a new 14t motor, I do not know- but my guess is that the test motor and my motor could be compared to one and another, think that the 2t difference is eaten up by the age.

I today only have the supplyed 17/23t pinions, but I do also have a couple of 22t pinions, from past Tamiya kits, I guess they should be 48dp pitch, but when I roll the pinion on the spur, they do not fit the mesh as good as the supplied once.

So could anyone help me out with ideas? :thumbsup:

Thank you in advance!

Your old Tamiya pinions WON'T be 48 dp as Tamiya only introduced 48dp for the 501 and DB01.

I ran a 12x1 (modern) motor on an 18 or 19 pinion depending on size of track. Don't assume that your old motor will handle a larger pinion, that might be a sure-fire way of killing it first time out.

Ok, thank you for the quik response.

So I will go for the 17t for now, will bring some more home to choose from.

Could have sweared on that they where 48dp, but its a while agoo they where used, so my mind is prob. slipping. Dont even know what car they are from, could be, TT01, DF03, TA05 among a couple of Kyoshos....

Well well, thanks!
