AplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusplusqweqwjmmmNice and handy unit. I successfully measured the KV and RPM. The easiest way to connect it is through the battery's balance lead (solder 2 bare pins in the lead and connect them to any size battery, mind the polarity)
Th screen displays volt, KV, rpm and motor poles (most motors have 7 poles). The meter has two buttons: A changes the major reading display, B choose the motor poles. Weight 13gr. Come in a nice protective bag, like the hobbywing escs...(?)this unit measures the RPV, the voltage of the bat and the KV, it is really simple to use.Bought it, easy to use and quite small, only LCD readings no backlight, can read (rpm), battery voltage in (mv) and motor (kv) ratings but you have to know how many motor poles say 12, enter 6 with button B, otherwise its inaccurate. No hassle form me. 5 starsso small and read rpm, kv and voltage manual is under tab. great to leave it in side plane's belly
