410 gearing with 8.5t in for Worksop?

[brooksy]

Just wondering if anybody could give me a rough idea what pinion to run with the above motor with kit spur for Worksop?.
I've currently got a 25t pinion on,could I go higher-26/27t?

Which 8.5t is it?
I had 24t on sp 7.5t and worked well on rd2 so 25t on a 8.5 sounds reasonable as a starting point.

It's a skyrc motor. Not a top brand but my friend has one in his k1 and it went well at Worksop.
I'll see how it go's in practice with a 25t on and go from there.

Stick a 5.5t in it

Been there,done that........not good.

I've got a 23t with a reedy sonic 8.5 and it runs cold
