Hello Tamiya fans! I am upgrading my tamiya TL01 chassis and I have some questions...I want to replace old brushed silver can 540 motor and mechanical speed controller with combo motor...so I chose to replace the brushed motor with this one https://hobbyking.com/en_us/hobbyking-x-car-brushless-power-system-4000kv-60a.html ...but there is a problem in specification I cant find the dimensions of the position of threaded holes on brushless motor (see picture below)...I also contact the hobbyking store and they are not sure if this motor will proper fits into the mounting holes on chassis...maybe has anyone some experience with installing this motor? I am also woundering about ESC "Running mode"...in specification is written "Forward only or forward with reverse (user programmable mode)" in case of setting "Forward only" what is the purpose of the button reverse on transmitter? ...is use only for dynamic brake? ...is this setting useful for prevent the pinion gears damage? ...I also need some advice about the proper 2S lipo charger...which is enough "smart" to stop charging when the battery is full? ...thanks.
