Manufactured by Uwe Scholer of Germany, the Striker series of chassis have become the benchmark for PU or rubber tire racing.  The manufacturing and production quality is very high.

The 5513D has a 55mm wide base plate with a thickness of 1.5mm.  The base plate has an opening that is sized to fit the range of popular 13D motors including the Fox 10, Fox II, Falcon, Cheetah, etc. The motor bracket positions the motor flush with the bottom of the base plate to reduce the CG.
