Quick Question...
 

Do parts from the Shuttle Z/ZX/ZXX work with the challenge? Reason Im asking, I need a Main frame and Stablizer Bar arms for my Challenge, but all the online stores sell parts for the Z/ZX/ZXX. Thanks Everyone.

Nearly all Shuttle parts are interchangeable. At least the newer ones anyway.
The Z/ZX/ZXX all use the same frames as the Challange as long as they are the newer style.

The Challange has the top start system. As long as the frames have the mounting points for the top start, they will fit.

Stabilizer arms are the same.

If you use century / heli-world for ordering parts, just type the part number you need into their search engine. It will pull up the right part for the challenge.
