The PC-01 condenser is ideal as an upgrade if your RTR car is to be equipped with a high-quality Savox servo, but the internal BEC of the controller does not provide sufficient power.
The PC-01 has a capacity of 2700µF. The use of this back-up capacitor prevents voltage dips best. Of course, the PC-01 can also be used in rc planes or rc helicopters.
Please observe the polarity!
