车燈聯动控制會有說明書教怎樣安裝?
No need. Just need to connect 2 x 2 pass thru' connectors (2 x in/out) to Channel 1 & 2 of receiver, steering servo and ESC. You can try yourself easily, just be reminded the +/- polarity, usually the brown or black wire side of the connector is -ve and should be to the right of the receiver (or check the manual of your receiver)
電調即是電變?
Yes = ESC (electronic speed controller)
遙控,馬達不用upgrade?
Common motors and radio control do support forward or reverse, no need to upgrade.
