the controller is another factor. the sbcg is by far superior.
independant buttons, better switches, an improved charging plate and telescopic aerial make for a big improvement over the box-like original controller.
if you do have a lot of freinds and are intending to build tracks then sbcg is the winner also. bcg has 4 frequencies (27,35,40 and 57) where as sbcg has 6 (27a,27b,27c,40a,40b and 40c).
and if you have ever been a collector in your life of any sort then you might also consider that collecting multiples is a bit of a waste.
the shells and chassis are a vast improvement in the sbcg range, far more detailed.
the sbcg and bcg both use the same parts, although the ease of switching front rims on the sbcg is a matter of unclipping Vs. having to remove pcb cover, lifting pcb, unscrewing then dissasembling front end (dont loose the steering spring!) swapping the new front wheels in and then reversing the whole process.
sbcg official upgrade kits are available and contain more than the bcg kits do. there are two types, speed and technical. they both contain a mix of parts i.e the speed one has gears and suspension. bcg kits come in four varieties: tires,motors, gears and suspension.
hope this helps…
