XRAY - Model racing cars

just got my xb4:-) 2014. any build tips or set up ideas?i run on 2 tracks. one is tight indoor small med traction dirt and the other is large for tenth scale outdoor with a roof.

one suggestion i have is there are a lot of different length bolts. its easy to grab the wrong bolt (too Long) and strip out a part. make sure you have the right length bolt by measuring all of them.
xray, maybe a plastic part to stick the bolts in with a line of each length would be nice. instead of using a caliper for every bolt.kinda like a droop guage that the bolts get put into.

If you are refering to different lenght of screws than you can easily match the screws to the screws that are shown in the manual they are printed 1:1 and in every section are shown just the ones you have to use.
