sam the 5.5 refers to the number of turns on the motor and iirc 5.5 is roughly equivalent to a 9 turn brushed.
In simple terms its gonna go like smelly stuff off a digging stick!!

Castle quote it as being equivalent to a very good, 9 to 10 turn brushed motor. What size spur is currently fitted?

Ah right cheers I looked on the novak site they have a chart, it refers to the amount of turns then.
The spur gear is the standard one I presume its the P Booth sig addition used once .... not sure if that 83? Castle hasnt arrived anyway yet looks like I've been pulled up by customs again

Track?
What size track are you runing on?
I would start around 21 on pinion but that just depends on track. Also if your bashing dont let the motor get over around 160-170 just change the pinion to achieve the proper heat of the motor. Jeremy

The Castle combo turned up today and I had ordered a 21t pinion that came the other day.
Holly flip its quick !! Just playing about at home I'll keep an eye on the motor temp thanks.. One thing that was a pain was the Castle motor has three screws through the can either end so you cant slide it into the Cats motor mount without removing them.. doh
