3D-printed Wheels & Parts for the Fun Scale Models B-24 LIBERATOR
Derek Micko's Fun Scale Models B24 Liberator "Wongo Wongo" is a masterpiece, a real "cut above" the other airplanes in his squadron. Although it has many features such as 4 motors, scale wheels and retracts, and 2 working bomb bays, it goes together with the same techniques and the laser-cut balsa kit will be available soon at Manzano Laser Works (click here). Derek has a detailed build log for this model, that you can see HERE. Here's the debut VIDEO for the B24 on YouTube! Rabid Models is partnering with Derek to produce custom 3D-printed parts just for this plane! Many other items that you'll need are available from Rabid Models, such as the motors, ESCs, propellers, servos, connectors, electronics, etc. Its a long list! We've produced 3D-printed black rubber "diamond-tread" tires and fantastic scale mag wheel hubs for the main landing gear, along with a scale nosewheel and hub. You can add decorative strut covers to the main gear legs. We have an "acorn" prop hub (steel or plastic) that screws onto the prop adapters, and we have the 5" propellers. The small parts collection includes control horns, washers, sleeves, connectors, and gear wheels for the working bomb-bay doors. There are 3D-printed 2.16" model 500-lb bombs. The FSM B-24 uses a specially designed 3D-printed locking 95-degree micro-retract unit. We have most of the servos you'll need, along with some other items like pushrod micro connectors. And we've designed some specialized sanding tools to shape the leading edges of the wings to the correct NACA profile specified in Derek's drawings. B24 SMALL PARTS SET "A" - includes the following 3D-printed items: (3) 1/16" wheel washers, (2) 90-degree servo mounts for the nose retract, (2) small control horns for the ailerons, (2) micro torque-rod connectors for 0.047 wire, (2) micro 90-degree wire connectors for 0.047 wire, (2) connector sleeve for 1.5mm to 0.047 wire, (2) large rudder control horn, (4) 1/32" washers, (1) elevator control horn, clear plastic tube material, (4) eight-sided control horn with double-axle flange THE B24 MOTOR PACKAGE includes the following items: Four 10gm 1811 2000kv brushless motors and four 12-amp ESCs with connectors, four motor mounts, four 5x4.5 propellers (2 Std, 2 CR), and four prop adapters. You will also need four propeller hubs, available separately (choose either steel or 3D-printed ones). You will most likely need some servo wire extensions and 3 short Y-adapters, unless you use multiple throttle channels. These are available separately. You'll need to make your own wiring harness for the motors and Derek used a separate BEC for the electronics. ATTRIBUTION NOTE: the 3D-printed "locking trunnion" retract was NOT designed by Rabid Models. This is "Landing gear retract rc V2" by user "cerro94" shown on Thingiverse: https://www.thingiverse.com/thing:1418261 and is licensed under Creative Commons - Attribution. Rabid Models modified the trunnion and is manufacturing & packaging the retract in a smaller size specifically made for the FSM B24. General Notes: 3D-printed parts are PETG (except for the tires, which are TPU) and are unpainted but require very little preparation - they can be painted with any plastic-compatible paint. Painting is recommended because all plastics will deteriorate over time if exposed to sunlight. The propeller hub is designed to use a 5mm steel hex nut and screws onto a prop adapter. The decorative strut covers and wheel hubs can be glued together with CA or Foam-Tac cement. The scale wheel hub halves are designed to be glued onto the tire and have starter holes for the axle - drill out the holes to match the axle wire size you are using. The strut covers are designed to fit around 1/16" music-wire landing gear wire (as specified in the kit instructions). The other 3D parts are utilized as per Derek's instructions and his build log. The retracts operate with specific servos and other parts are required to be supplied by the customer per Derek's plans, such as various sizes of music wire, cardstock, plastic sheets, and wiring.
