My 12 year old has built this from his mind, so please be kind. :) This is a semi-automatic 2 gear transmission. He is having trouble getting the torque done correctly. We know the car is heavy for how much torque is required, but at a bit of a stale-mate on proceeding. Any advice on where to go for answers? I feel almost like we need a real mechanical engineer who also does LEGO! Thanks for your help! submitted by /u/Gold-Negotiation-636 [link] [comments]
