hi

basically the master car sport and master car race were made for the use in normal 1/10th scale cars. logically it says on the case 5-10 cells or 2-3 lipo. now of course thats with the BEC. so if you cut the BEC then they may be used with higher voltage as so many other escs. i remember one guy that had an e maxx (3906) running a master car race with a plettenberg maxximum on 12c with good results five years ago. i guess he had also an external bec. i am not sure. the controllers back then had both logos on the case "hacker" and "jeti". today they are sold under the "jeti" flag as far i can see it.

in 2003 those escs were called 'master car sport' and 'master car competition'. i guess the competition is now the 'race'. of official specifications then were 66A current for the sport and 111A current for the competition. if that is still correct then at least the official specs of the sport are lower than the MM.

i have also read this interesting setup of your colleague running the master car sport in a savage ( and he mentioned to try then in his warhead) with 5s and reporting cool temps. i guess his nickname is 'takedown' or the like in rcu. to be honest that is somewhat surprising. however if it works its great.

the quality if those controllers is quite high imo. for instance the case is full aluminium. they are said to be smooth and you can set a 'current limit' etc. i have a master car race here i may try with 4s and an external bec in an lightweight MT (revo) and see how it does.

so i guess for 85 bucks you may give it a try with the 'sport' but nevertheless i would watch the temps closely.

bye
