Default Gearing - 64 vs 48

Hi,

I'm thinking of getting some 64dp spurs for my T1FK05. Now, q's:

1) 64 better than 48? (I'll be racing touring)
2) What size of the spur do I want?
3) Optimal combo for around 7 to 8 final drive ratio (internal on FK is 1.7)
4) Kimborough spurs good?
5) Final q: should I get 64dp spur and 64 dp pinion, or 48 dp spur and 48 dp TITANIUM pinion.

TIA

Basically if u race outdoors on tarmac u might wanna stay away from 64pitch gears(unless ur using team losi xxx) cause the stripped easily.

Compared to the 48pitch gears, the 64pitch gears would definitely be smoother but once a small stone jammed ur gear it would be stripped.

So I would definitely recommend the use of 48pitch gears if u plan to race outdoors and 64 pitch gears if u wanna race indoors on carpet.

Just my 2 cent!!!

I prefer the 48dp gears too,infact im still on the same spur gear that came with the kit,4or5 years ago Must be a record lol.


Was forever chewing 64dp gears on an old yokomo and a pro2 outdoors. Small stones are evil,I can imagine even moreso in a tub chassis for example as they wont shake out easily during a race. I just think theyre a little more fragile than 48,so I steer clear of them myself.

You have the same adjustment ratios on 48 so can't see any benefit of them really. Guess its just personal preference.

Default 64dp

My son and I use 64dp on a RDX and never really had a problem. Only once recently when a motor moved, but then a 48dp would have been damaged aswell

We use 64dp to get as close as possible to the right ratio for a track.

Try it and you will see.

64 is smoother than 48. Most touring cars uses 64.

Spur sizes differ on the ratio and final drive you want for your car. If you want more torque, then you should set your final drive in higher ratio. For speed, lower ratio.

Speed mind spur gears or HPI spur gears will fit perfectly in to you FK05. I am not sure about the Kimborough. I haven't tried them yet.

For your last question, If you use 64 on spur, then your pinion should automatically be 64 too. Same goes to 48p. As I mentioned, 64 is smoother and better for most touring cars.

if you race stock - probably 64 is better, even outside, as you can change your rollout by smaller steps,

for mod - im racing 48, and i find it to be better in all applications

64, 48...

...it all depends on the driver and availability on LHS around your area. We have both the 64 & 48 available here in Manila but most drivers still uses 64 on both stock and mod classes.

I use 64dp for many years and never stripped one! I prefer them since the choice of ratio is bigger and they are quiet. Even in Offroad (many yrs ago, some of you weren't born yet )I used 64dp in my Schumacher cat (first series with the epoxy stick chassis). Nowadays 48dp is prefered for offroad and 64dp for onroad.

ditto with a few previous posts. i've ran 64p in outdoor touring for awhile and can't say i've had any more/less problems than when i was running 48p. the ability to make finer ratio changes is what i feel to be the real advantage.

I have had nothing but problems with 64 pitch. I know I'm setting the mesh properly, it's just a combination of bad luck and the general poor quality of spur gears

I've run both and prefer 64p. Having much more gearing options definately helps in finding that sweet spot for stock motors. I use Xenon spur gears and they have worked very well.

diameter of a 64 pitch spur is smaller than the 48 pitch spur. maybe you need a different combo for your spur and pinion. may i ask what final drive are you trying to obtain? and what car are you using? (for its internal ratio)
