mabuchi or nanco i think running most a lot better as Maxon motors - Nicks build very good machines with the nanco ,very fast and good power -and i run the same machine after 2 years daily use without any issue. Dan Kubin have change the motor back from maxon to mabuchi because they are better running and i notice this with a lot other machines too. Maxon i think its only expensive and maybe its better to change from time to time the motor for 30 bugs as to buy a motor for 200 usd and have it inconsistent running after 6 month. I notice the maxon change after a few month the consistence and power and get softer with time. The only expensiv and very good brand i can recommend is faulhaber - the are strong but a mabuchi or nanco is not bad as a faulhaber -but all most better as maxon
