Quickboost has issued a replacement "tail wheel" for the Kinetic S-2 tracker. It really isn't a tail wheel, but rather a tail skid. The parts are three – a tail wheel, the skid, and the piston. It is well cast in Quickboost’s gray resin. You separate the parts from the casting blocks, sand the minimal attachment points, and assemble the wheel by adding the separate tire.

One thing to note in the comparison photos is how blob-like the kit parts are – almost no detail whatsoever. The kit part is molded as one piece, lacks any wheel hub detail, and will also need filling as there are definitely some sunken-in areas.

If you are building this kit, this part is a must-have! It is recommended, especially due to the low cost and improved detail. My thanks to Quickboost and IPMS/USA for the chance to review this excellent item.
