The cheapest alternative for brushed motors. Good quality and minimal cogging, motor construction the same as ezruns, yeah racings and other clones. Motor is not exactly a 540 version but 380 in specially designed heat sink can. During driving heats more than 540s but still on the acceptable level. Fits very well for all rc chasises. After wearing of the bearings you can easilly replace old ones by new which can be bought on rcmart too and donate a motor second life. Regarding ESC, no bigger problems because set contains a program card and anybody could adjust all necessary parameters. Summarize, good choice for all who wants to buy their first brushless system, and don't care about special instructions how to use and do not overheat motor. Set can survive huge tortures without issues, At the moment BEST BUY on RCMART !!
