gearing querry

[JOOTZ]

i was trying to order parts for my RF yesterday and got stuck on the pinion gear teeth. would appreciate if you guys would fill in the blanks so i could get going on this build.
i have high speed gears and a dig unit coming, please include those in the math.

35T motor
pinion gear
?? P
?? T
spur gear
81 T
?? P

55T
pinion gear
?? T
?? T
spur gear
?? T
?? P

i am looking at the tekin FXR 35T combo since i am familiar with it from experience on my MRC build and i already have the hotwire. if you could link me up with part numbers for the spur and pinion set for both a 35T and 55T so i could make a decision i would owe you guys for life, NK.
i also cant find a hitec 5965 servo anywhere, what you guys recommend and should i use the same servo for the steering and the dig ? TIA

i use 48p 81t spur and 22t pinion with a 5t cobalt.(could still use way more wheel speed) i tried a 35t but couldnt get enough torque. i need to order hsg so dont know yet where ill end up.

This should help you figure it out...

i got the HS gears coming are you thinking go with the 55T and stay with the spur and pinion set-up your using now ?

im gonna run the hs gears with the motor and gearing combo i have now,,81t spur and 23t pinion,,,should get it pretty good

i think im going to stick with the puller but yeah i think 81/23 should be the ticket with the hsg's

got that, thanks chief. now comes the hard part-buying/LOL

i've got the 18/86 with hs gears and a 55t on 3s and dont have the torque that my axial does with a ~27t motor with a final ratio of 55:1 on 3s. my axial will climb straight up a wall and doesnt think about stoping and my rf gets 2" up and stalls. seriously wtf?
both trucks have the same exact electronics setup except for motors so that aint it.

whats the deal?

try 86/23

i dont have a 23 but i do have a 25 and tried that and it was worse perfect wheel speed but no torque. im ordering a hhh35t here pretty soon and i think that with the 18/86 will be good. of course my 55t is like 2yrs old and sees mud and water all the time. idk but maybe my 1lb. each wheel and tire combo might be doing it. i guess ill just keep playing around with it.
