RC10 - original gear/ pinion set up ?

[zakspeed]

In the process of finishing my original gold tub RC10 runner. I'd like to put a decent motor through it. The spur gear is a 54 tooth, i have a spare 13 double (will this be any good) if so what pinion should i run. the manual dosnt give any pinion sizes but the picture of the motot shows what looks like a 13 tooth pinion?

I have an 11t mtroniks will this do for the 13 double?

any help greatly appreciated - cant wait to get this running

A 13 double is a bit of overkill for one of these. I would start with the smallest pinion you have and work up from there to avoid overheating.

Which gearbox is in there first, is it the newer 'stealth' transmission (three gears inside) or is the original RC10 gearbox (diff on the spurgear and two seperate gear sets in the box)??

The 54 tooth spur means you are running the original 6 gear setup with a 32dp spur gear. using a 13 turn motor is probably pushing it a bit for the gearbox, at the time of the original car a 21 turn was fast.

I would recommend replacing the spur gear with a 48dp one, it will fit straight on. You'll also find it a lot easier to get hold of 48dp pinions as 32dp pinions are impossible to get hold of. Most runner RC10s will have the stealth gearbox fitted, it is more efficient and handles a lot more power than the original one.

Gear ratio will depend on where you are running it and how you are running it. I run my RC10 on racetracks using a 17 double motor and it is geared properly with a 14 tooth pinion and 96 tooth spur. If you want to use the 13 turn I recommend the largest spur gear you can get, in 48dp either a 93 or 96 tooth. Start with a 10 or 11 tooth pinion and work your way up from there.
