ermm yeah ok the bacics i havent been drifting for long so here goes
1.)rear camber 0 - +3 on both get it as low as possable use some chalk an run a single line round the whole bottom of the chassi run it for 5 mins and check if it all worn off rais it 1mm and if it not touched lower it 1mm and keep on doing that untill it is rubbing the chalk slighly,this is the ride height
2.)balance the car this may mean adding lead weight to one side of the car or movign the ESC or seciever or even the stearing servo in my case had to butcher it up good

poor SST
3.) hard compound tyres or even electric tape over the tires but make sure it goes clock wise around so that when your running it doesnt unravel
4.)locking the diffs with ball bearing diff take them apart and remove the balls and tighten back up for geard diffs you can simply jam blue tack in there and it locks it and is easy to take out(with time) some people run with locked rear and tight frotn and other go with both locked its personal preferance so try it out
5.) gearing is also personal but you want a low gearing to the acceleration is high because top end speed doesnt matter so go for a small pinion and big spur
6.) in my oppinion belt it better for the pure reason you get no torc roll baced by the prop shaft but some people dont see the difference so its persnal choice again
7.) seventh and most critical is HAVE FUN and enjoy your progress
