ASSEMBLY MANUAL B-25 Mitchell ARF - RC DEPOT

Section 9: Retract Valve and Hardware Step 4Install the air tank in the pre-cut position below theradio tray. Follow the installation diagram instructionsfrom Robart to hook up the remaining air lines. We haveincluded enough extra air tubing with the optional airkit to allow for ease of connection. Use approximately 6inches of air line between all “T’ fittings. Add a few dropsof medium CA at the arrow to secure the tank in place. Step 5You will need to make a decision at this time abouttransporting the model. If you plan on taking the twowings halves apart for transport, then you will need topurchase two additional quick disconnects (1 pkg.) andplace one quick disconnect in each of the main retractlines just before the “T” fittings used to connect themain retract lines together. If you will be leaving thewing together, then you will only need to install the twoincluded quick disconnects inline so the wing can beremoved for transport. Step 6Pump the retracts up to approximately 100 PSI so youcan test how long the gear will hold air. Both the up anddown positions must not leak, but obviously the mostcritical is when the gear are retracted for flight. The gearshould maintain pressure and only lose a few PSI (lessthan 10 PSI) in 30 minutes. If the retracts will not hold airthis long, then please refer to the Robart troubleshootinginstructions on our web-site at the following URL:http://www.hangar-9.com/Content/RT.pdf53
