Here at YB we are always glad to present new Lego GBCs. ANd today is one of that days. The youtuber 05yattaran has posted some new and elegant Lego GBcs in his youtube page:
Although this module may not seem to be technically complicated, when we aproach to the rear part of it we can see the gearbox which changes the speed.
GBCers used to used a Lego Speed Regulator for this function but it is an old piece and not easy to find, so this solution is brilliant!
This second module is not as complicated as the previous one, but I like it as well. The colours used and the style of the Lego Pieces he has used has impressed me.
