This is the original “Mark Hale” design tail wheel spring kit. Don’t be fooled by other spring kits that don’t include all the hardware and that have springs that are big and clumsy.

Our kits come in two sizes, standard which will fit all 25% to 40% airplanes. And our H/D kit that has stronger tension springs but remains the same size and comes with all necessary hardware and will fit 40% and bigger.

This is the most complete and best designed tail wheel spring kit on the R/C market to date.
