rb5 pinion?

[barry]

What is the box standard rb5 pinion size and gauge? And is it a good all round choice?

Thanks,
Barry

I've found out the gauge I need - 48dp. Bearing in mind I have no regular track so can't say whether I'd usually be driving on a twisty circuit etc, what would be a good all round pinion (or 2 ) when using a 6.5t brushless and 78t spur.
Thanks,
Barry

21 - 22 - 23 is what I mostly use outdoors.

what do most of you use a motor in an RB5?
I ran a (CS) 7.5 in mine this weekend in Kampenhout (Belgium, astro) and I seemed to have a lack of power.
I used an Tekin RS Pro so no problem there.
I use the same combination in my Predator (4WD) but with a 6.5 in stead of a 7.5 and have plenty of power there, even when using a regular throttle profile on my Tekin ESC.

I ran a 78-spur in the RB5 with a 26-pinion.

5.5= 21
6.6= 22/23
7.5 = 24/25

maybe you were a touch over geared but shouldnt make that much difference
what lipos were you using ludo ??

i used an old Trakpower 4200 and then an LRP 5200-lipo.
still had the same feelings of lack of power... but could be me?
I used a 24-pinion but the switched to an 26 because I lacked the topspeed of the other drivers on the long straight.

funny thing, with the 24-pinion I ran very good the previous week on a grass track (also with long straights) and the car had plenty of "go".

do you guys seriously use an 5.5 in an 2WD RB5? wow. Seems a lot of power for such a small car.
I have plenty with a 6.5 in my 4WD Pred.
