+ and - with BL


+ No maintance, you could have the engine and ESC for 10 years+ with correct spur/Pinjon kombination and good looken after
+ Good performance, for grip racing it's compared with a 10-12 Turn racing engine, but in drifting it has the bottom end needed
+ Nice with batteries, The batteries hold much longer than a brush motor with the same performance
+ they are expensive like 2500NOK (220 $) buth with a competition Brush engine you need Motor, ESC, "Brush Changer" and may brushes and that has a total of three times as much!
