If i buy the TB mini remote, will the carbon fiber cover block the signal?
It may but you could always put the antenna outside of the deck.
P.S. I sell the same remote for 50% of the price 
Is it the exact same? Will i need any extra connectors?
Yep its the exact same, and can ship tomorrow! Most ESC’s have the correct 3 pin PPM connector so you shouldn’t need any extra connectors.
*Still depends a bit on setup like dual VESC etc
