C.Andy’s have produced this AHA race management system for clubs and event/series organisers. The system places a small circuit board between the LiPo and the ESC which limits the electricity delivered to the ESC. The amount can be easily programmed by the organiser and easily checked through the use of LEDs. If the racer uses too much power the system will blink red and the driver wont pass post race scrutiny. The idea is to equalise the power from different ESCs, batteries and motors for example if you are using too much timing, you will use more power.
