The Crater 46 has a constant current rating of 46 amps. This means that this ESC can withstand and deliver 46 amps without overheating. Rated for 55 amps for a maximum of 20 seconds. Any amount of current higher, or for a longer duration, will damage the ESC. Rated for batteries from 3 cells (3s, 12 volts), to 6 cells (6s, 24 volts), meeting most multirotor applications. The Crater 46’s mounting pattern is 30.5mmX30.5mm, which is standard for multirotor with prop sizes from 3” and up (5” or more). The hole size on the board is M3, which means that a 3mm bolt or screw will fit through the hole. The Crater 46 is running BLHeli_32 firmware. This firmware has been written specifically for ESCs with 32-bit processors. Older ESCs ran slower processors, so they relied on 8-bit firmware, like BLHeli and BLHeli_S. The faster processors also give the ability to run fast throttle response protocols with lower latency (delay).

Open the program, connect your FC to your PC, hit the “Connect” button in BLHeliSuite32. Once you are connected, plug your battery into your multirotor. Now hit the button marked “Read Setup”. You will now see your 4 motors' information displayed in the configurator. Look for the setting marked “Motor Direction” for each motor. Reverse the direction of any of your motors that are not spinning in the right direction. Then hit “Save” and exit the program. Go back into Betaflight and test your motors again. If they are spinning the right directions you are ready for props and a maiden flight!
