Sariel posted a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingWake up Samurai, we have a buggy to fix ;) In all seriousness, I think 42124 is a great modding material and my first step was trying to boost the performance while staying within the confines of the Control+ system. A detailed explanation and demonstration is in the video below, and the short story is: - with vanilla 42124 and regular 1.5V batteries I'm getting between 4 and 5 km/h - by adding a second drive C+ L motor and gearing the two motors up 1:1.6 (theoretically that's 25% more torque and 66% more speed) and still using the same batteries I got between 5 and 6 km/h - switching from regular 1.5V batteries to 1.2V rechargeable Eneloop batteries produces speed of slightly above 6 km/h I'm not happy with these results, it seems like the last iteration has a lot of power but it's actually only slightly faster. My conclusion is that the power supply is the limitation here, and to see a significant increase in speed we'll have to double it or replace it with something else, or go full PF on the 42124.
