I am using a Viper EXC and 7.5t motor (sensored) and a 23t pinion. This will have the power turned right down until my driving improves!!
However, when i turn one or both wheels by hand, or push the car along the table, its really 'notchy'. Is this normal? if not what could be the problem?
The car came with a few spares including the TLR diff rebuild kit. As I don't really know the cars history, am I better off just rebuilding the diff using the kit anyway?
Also - daft question time. When i spin the wheels in the air with the motor, they balloon up (like the monster truck tyres etc). Is this down to crap tyres (they are brand new and pre glued by the last owner - bowties), or will it sort itself out when actually going down the track?
Many thanks - Jim.

I will bring the car with me, if you have a few minutes to spare to have a look over it for me, would be really appreciated. 'Gnarly Old Dog' - what colour is your car/whats your name so I can find you for a chat?
I agree with you all on the speed of the motor, but it has a programme card where it has a profile (pre-made by the factory) where it only delivers 60% power (as well as a few others). Will this not tame the motor while I improve then i can slowly up the power output?

I must add that the advice you've received here from
Frecklychimp,
Gnarly Old Dog, &
Garry Spice is pretty much spot on.
Otherwise, being as you purchased a
used car - I would suggest giving the car a complete disassembly and maintenance treatment (thorough going over). There's really no telling what problems have been left you from the previous owner, some gears might be chewed in the tranny or bearings need cleaning or replacement, and it might need a good going over to make sure it's up to snuff. You just don't want your first day at the track to be any more of a hassle than it's already going to be due to unfamiliarity of the track and getting used to the car (so you don't spend your time there just wrenching).
As others have mentioned, tyres are really the most important part of the equation of getting around the track - you'll find those dirt tires you have are going to be basically useless. But you'll see this the first day rather quickly.
Otherwise, as others have mentioned, your motor choice is really over the top (especially for a newbie), unless you happen to be running a large outdoor 1/8 scale track. And while being able to turn down the power 60% will help some, it's probably more advisable to look into obtaining something in the 10.5-to-13.5 range for anywhere you're going to run indoors (and save that 7.5 in the pitbox as a back up, or running elsewhere).
