IMO building kits it's nearly as much fun as driving... Sometimes more...

Tamiya kits are the best. There instruction are very similar in layout to Lego instructions.

best tips for building from a kit.... Take your time... Its a learning curve. Don't worry about how long it takes...

One thing I highly recommend is YouTube... There is basically a how to video on everything, even build series of some popular models
for things like:
filling up the shocks with oil
filling up the diff with oil
adjusting the slipper
adjusting the gear mesh
running in nitro motors
i would recommend reading the manual but also watching a how to video.

One thing I've done in the past and still do... Before I buy a car I generally download the manual first to have a look and familiarise my self with the vehicle and most importantly factory upgrades.... Some vehicles have little cheap upgrades that are worth fitting as u build it. Example.. TiN coated suspension pins....and for 1/10 Tamiya stuff there is things like carbon gear shafts, hardened diff yokes, steel gear pins and in some cases alloy bellcranks, and servo mounts.... Generally no matter what car there is always something
