It is not a question of which is better, just which one will fit best.

Most modified drivers use high 80's and low 90's spurs.
For stock 10.5 I would use spurs between 78 and 83. That would work fine...

And if you want to run mod, spurs like 84 and 87 will do the trick
At least they did with me with a 4.5 motor

Thanks for the clarification. I guess I should have focused my question a little better- sleepless night lol. My real concerns are spur gear diameter to wheel diameter: I plan on running bsr's out the box at 60mm and I worry that getting too big a 48T spur gear puts the teeth uncomfortably low as the tires wear, and getting "too big" a spur gear limits the tuning affect of placing the motor towards the rear for more weight transfer

I also run BSR tires and UFRA's. Also start around 60-61mm and I run them up to 54-55mm.
I never have to worry about my spur hitting anything. I mainly run a 81t. Trust me, with stock 10.5 boosted or blinky almost all rollouts can be run with a 81t. And you don't have to worry about the tire diameter.

Have been doing that for 5 or 6 years now...

Just realized my trusty Futaba s9551 doesn't fit the included servo mounts... I would like to use this servo as I have a couple spares but if there's no servo mounts that will work for my servo, is there a recommended servo that will fit?

Can anyone give me a ballpark rollout for my Serpent S100LTR? Will be running 10.5 blinky on 2s on a fairly long track. Just a starting point would be good as I have no idea with these cars lol.

Cheers
Simon

Depends on how long the track is.
If it is a nitro track then you could start out a a rollout of 55 and work your way from there.
We run about 60 rollout but this at the big nitro tracks in Europe.

Cheers Roy, it's a pretty long track that runs 1/8 nitro fairly comfortably. Will give 55 a go and take it from there. Thanks again
