Here it is guys im running a 1/12 scale pancar with tekin rs pro what is a popular setup for a booster for one cell lipo currently im using a receiver pack that connects directly into the receiver but it sure is taking up a lot of room is there something else i can use besides a receiver pack.Thanks

I have used a couple of these:

I added some heat shrink around them for safety.

Boosters work great but I prefer a pack. You don't need much of one. On Tekins, I use a tiny little 180mah lipo wired into the switch.
