Face Spinner
A Face Spinner (FS) is a type of spinner, but with the weapon motors facing forwards with small discs on each motor and weapons on them (parallel to the motor's axle). Despite having generally a weaker weapon than HS and VS and not being able to toss opponents like VS, they do continuous damage and have very fast spinup time. Plus they do not wobble if they lose weapons.
An in game example is Coal Miner.
Other notable Face Spinners are Meganerdbomb's BBEANS 2 entry Shebeast (did pretty well) and Rejected's bot Rabid Pit Bull (one of the best stock FS ever built).
The best Face Spinners are fast and use wedges to get under opponents and hold them there while the weapon grinds them down. Depending of your style, you would choose either iron spikes (for strength) or razors (for damage). Razors are a good choice if you really can get under your opponent and pin it like Rabid Pit Bull.
A well-built FS can be devastating. See Rabid Pit Bull.
