Float Set For FMS 1700mm PA-18 Super Cub
by FMS

The Float Set for FMS 1700mm PA-18 Super Cub (SKU: FMSFLT006) is a dedicated seaplane landing gear conversion system engineered specifically for the 1700mm wingspan FMS Piper PA-18 Super Cub (V1 and V2). Molded from lightweight, high-density EPO foam, these floats feature a hydrodynamic stepped-hull profile designed to break surface tension quickly, reduce drag during the takeoff run, and deliver smooth tracking on water surfaces.

Engineered as a direct bolt-on upgrade, the float set replaces the aircraft's standard tundra landing gear utilizing factory fuselage mounting points without requiring cutting, modification, or adhesives. The system includes an integrated water rudder with a pre-installed 9g steering servo and linkage rod, granting precise low-speed water taxi authority and directional control in crosswinds. Heavy-duty painted aluminum struts and diagonal cross-braces maintain scale aesthetics while absorbing impact loads during lake and river sorties.

Key Features

• Direct Airframe Compatibility: Engineered specifically as a drop-in conversion for the FMS 1700mm PA-18 Super Cub and PA-18 V2 platforms.

• Integrated Water Rudder & Servo: Pre-installed 9g sub-micro steering servo and articulated transom water rudder provide responsive steering during off-plane taxiing and docking maneuvers.

• Hydrodynamic Stepped-Hull Design: Dual-chine, stepped hull geometry promotes rapid planing, shedding water cleanly to enable short-run STOL water takeoffs and controlled flare landings.

• High-Density Molded EPO Foam: Resilient EPO construction delivers float buoyancy with minimal added weight while resisting dinging and water ingress.

• Rigid Aluminum Strut Framework: Painted aluminum main landing gear struts with cross-bracing maintain rigid tracking and withstand rough-water chop.

• No-Glue Bolt-On Installation: Mounts directly into the factory landing gear recesses using standard machine screws, allowing fast swaps between tundra wheels and floats.

• Plug-and-Play Servo Integration: Includes extension and Y-harness cabling to slave the water rudder servo directly to the receiver's primary rudder channel.
