The tail wheels that come with the original kit runs were sort of a gift from the manufacturing side of the process. They aren't the best available, but they will work until you obtain something better.

If you want the latest, greates, super light unit, give RCBlimbpro a call for one of his. If you're not overly concerned about the weight, get an Ohio tail wheel assembly. They work well and last forever. The newer Goldberg products are a bit on the soft side.
