Hey guys, got everything i need for 1 cell lipo. Its on the way, now i have a few q's

Here are the electronics i will be using: LRP SXX, KO SS Receiver, KO PDS-949ICS Servo, SP 4.0 ver2.

How do i power up the car? Im using the smc receiver pack It has its own internal switch. 450mah 1. What do i use? this switch on the battery or the speedo switch or both? What else should i know?

Should i rewire the electronics with 12 or 13g wire instead of 16? To get more current through

Do i turn off the "lipo cut off" on the speedo? How does the speedie work with 1s?

How does the set up get affected by the lower weight? Any major differences?

Thanks in advance,

Antoni
