Up for sale is a NIB, never used or mounted set of pneumatic gear for the 1/5 Ziroli Hellcat. The full set is made by Sierra Precision which are one of if not the best gear made out there. Set includes main and tail gear, 5.5 inch scale metal wheels and tires, and a 1.75 inch tail wheel. I bought them new from Ziroli but the project never materialized. I paid $905 for this set. Will sell for $800 firm. If you are looking for this set for your build, save yourself over $100 right here. Add 3.5% if paying through PayPal. Thanks for looking.
