Great write up.
Theres just a few things i think could be better.I.e.,
For the car types, like buggy, st,etc.You could write a little about what they are good for, like the st and buggies are good for tracks.And st and truggies are different, truggies are typically 4wd, sometimes have a wing, and a re more of a race bred truck.And for bl and brushed, i think it would help to explain how the turns are rated, and what kv means.
Maybe add motor break in as well.
Wouldnt change the rest.Again, great job.
