I have recently aquired a NIB Prettner Calyspo from Modeltech. It has Nib springair retract pkg, and a OS rear exhaust with pipe and mount also nib. Box shows storage wear but the kit and gear are pristine. Only work done was to fit the motormount to the firewall. May be looking to sell this as a package and wanting to know the value of this setup complete. Thanks for your input. Kenny, AKA chilechopper. [email protected]
