Slot.it chassis' take slot.it motor mounts.
The format (angle / side/ inline)  of the motor is driven by 
-  personal preference
-  the limitations of  the chassis (eg can the chassis support all formats?) 
- the limitations of the body (some car bodies and interiors hang low so can only clear certain motors and formats) 
- rules and regulation at the event you are racing. 

Offsets are an advanced tuning technique so I would advise not  to go that way initially.
Nothing wrong with starting with a sidewinder. Less likely to run into fouling issues during the build.

See pdf in the link below

Page 16 ( and forward) lists motors mount options. 
As soon as you can, go and visit your local club track even if you don't race initially, there is lots to learn there.

Tune in to worldwide slot chat next week. 
I'll be going through the motor formats. 

Watch yesterday's slot chat in you tube. 
Dennis did a good summary on the various motor types.
