[notatoy]

hi guys i need some help i am doing a nitro conversion , now the motor i have has a 3.17 mm shaft . i know i need a mod 1 pinion question is these pinions are 5mm bore so will i need a reducer ???? if so can some one tell me the one i need . oh and what would be the best tooth count for a 1/10 scale running a 3900kv motor .any help appreciated guys thanks in advance ..

Here is the bore reducer. Drop down screen/arrow will give you two options to choose from. http://www.rc-monster.com/proddetail...rod=RCMreducer

BTW 3.17mm is 1/8", so you would need the 5mm to 1/8" reducer. Just in case you were wondering....

We need more info to give you gearing recommendations.

Info such as vehicle make and model, battery specs, tire height, motor info, intended useage, mph desires, etc. Pictures are good too, especially of hot chicks. (this last part will not help with the gearing situation, but why not?)

Model Specs:
Length: 453mm

Width: 320mm

Height: 183mm

Weight: 2.5 kg / 5lbs

Wheelbase: 305mm

Ground Clearance: 25mm

Wheel Diameter: 100*51mm

Nice lightweight vehicle it seems, and the rollcage is interesting.

I would think the motor/esc combo will work alright, but I'd prefer an 80amp item myself for a bit more headroom. I dunno what the kv rating on that thing is though- 10turns doesnt mean much to me....

[suicideneil]

Gearing will depend on the kv rating of the motor, now we know the voltages and tyre diameters. Not sure what spurs that thing uses, but Im sure something from a kyosho or similar 1/8 scale vehicle will fit. The ratio is listed for diffs, ony says 1/8 scale, but I'd guess 43/13 probably.

hey neil the motor kv rating is 3900kv... i will check the spur today hopefully that will be enough imformation to reccomend a pinion of correct tooth count ,
