If this system was already purchased, the pressure tank can be mounted inside the top of the fuselage behind the cockpit. A smaller pressure tank that is compatible can be purchased alone-#172 Small Pressure Tank (ROBQ2372). To convert to retracts, here are the updated items; #TFB25 Robart Tri-Gear Retract System for B-25 Mitchell (ROBQ1624), #188VRX Standard Deluxe Air Control Kit (ROBQ2307) #190 Air Line Quick Disconnects (ROBQ2395) Standard servo to operate air control valve (HCAM0149) If a replacement fuel tank is needed, order the Sullivan 14oz tank (SULQ1742), or the DuBro 14oz tank (DUBQ0214). Some minor trimming and modifications may be required. This model is eligible to compete in the Fun Scale Class in AMA as well as IMAA events.
