you do have a rechargeable receiver pack, right? if youre still using alkalines, i suggest you get an inexpensive rechargeable pack and charger so youre servos will stay powerful much longer during a run.
you dont have to remove them from your car, unless youre going to clean the entire car with denatured alcohol and wd40. but you do have to unplug the battery pack or turn the switch off during storage.
im not familiar with that car's layout, but i can suggest the ff:
A. extension cable for the receiver pack
- buy an extension cable (one end male, one end female) for your receiver pack. connect the male end on the battery channel of your receiver.
- make a small hole on the battery box of your kit, enough for the extension cable plug and wires and the receiver pack plug and wires to pass through.
- now that the female plug of the extension and the male plug of the receiver pack are now accessible externally, you can just plug and unplug your receiver pack without removing anything. just make sure that the wires and plugs are away from any rotating drivetrain parts. also, to be safe, get a locking clip for the plugs so that they wont accidentally get unplugged while running your car.
B. switch with charge lead
- buy a switch with a built in charge lead. this way, you can just turn the switch on and off without plugging or unplugging anything.
- the built in charge lead will let you recharge your receiver pack while still mounted on the car.
- the downside of this is that the switch may get easily fouled up by fuel or other dirt and may short or damage your battery. so youll have to regularly check and clean the switch, or buy a silicone switch cover.
hope this helps
