I recently acquired a trackmate timing system with 6 transponders. The ends on the transponders are just cut off as in this photo. What is the best way to use them with the WLtoy 1/28 mini rc cars?
id find what the transponders max and minimum voltage are. and if it all else i would add a battery to power it. if rc has a empty channel id use that after adding a rx plug. you can always add a Y harness to use a used channel but have the voltage you need to power it. many ways
Yeah, either a spare servo port on your rx or possibly piggybacking off the esc (so it gets battery voltage if it supports whatever voltage you use). A separate battery wouldn't fit, I'm guessing.
