The innovative, 33.5” (850mm) span FMS Ranger is the perfect way to start earning your RC wings. It’s easy and convenient. No assembly is required and no experience is necessary. Fly at a small park, basketball court, or in your own backyard!
FMS is dedicated to helping pilots of every skill level experience the thrill of flying their perfect radio-control airplane. For first-time hobbyists, lack of space can be as much of an obstacle as lack of RC know-how. FMS therefore created the Ranger 850mm, a 33.5” span high-wing trainer with the flight innovations of the 1220m (48”) span FMS Ranger in a more compact size suited for flying almost anywhere. It’s the perfect way to begin earning your wings.
Like the FMS Ranger 1220mm, this model’s high-wing airframe and wide-stance tricycle landing gear provide forgiving handling characteristics in the air and on the ground, making it easy for inexperienced pilots to fly. The included motor, ESC and micro servos add to the lightweight, 305g (10.8 oz) airplane’s incredible performance.
Stable flight characteristics and realistic, general-aviation inspired design.
Quick and easy assembly — no glue or special tools required.
Small enough to fly at a small park, basketball court, or in your backyard.
High-strength tricycle landing gear for easy ground handling.
Constructed of durable, ultralight EPO foam.
High-wing configuration improves stability and lift at the slow speeds inexperienced pilots prefer.
High-visibility color scheme helps with following orientation.
Turn your dream of flight into reality at the controls of the FMS Ranger 850mm. One of the best platforms ever designed for learning to fly, this model features an array of innovations that boost your confidence while you learn at your own comfortable pace. Because of its compact size, you don’t need a special flying field — you’ll be able to practice in your backyard or at the local park. Even better still, this Ranger goes together quickly and easily, without requiring glue or any special tools. The easy-to-assemble airframe features durable EPO construction and is tough yet lightweight.
The Ranger 850mm airplane’s stability-enhancing high wing configuration, together with its low wing loading and ability to generate powerful lift at low speeds, makes it an ideal choice for new RC pilots. Its forgiving flight characteristics give you a comfortable cushion while you learn the ins and outs of model control. Wide-stance landing gear with a steerable nose wheel provides easy ground handling. The realistic, general-aviation inspired appearance adds to the excitement of learning to fly.
This Plug-N-Play model comes with a 3850Kv motor, ESC and four 1.9g micro servos installed. All you need to do is complete a small amount of simple final assembly, install your receiver and charged 850mAh LiPo battery, and fly.
