Introduction
Skill, know-how and space has always been limiting factors in
bringing new enthusiasts into the wonderful world of R/C
aviation, until now!
FMS has always been dedicated to enabling pilots of every skill
level to enjoy the thrills of flight. Innovation then, is in our DNA.
FMS is proud to announce the 850mm Ranger. Like its sibling,
the high winged airframe design with a tricycle landing gear, is
very easy to fly by default. A dedicated flight control paired with
a GPS sytem allows pilots to fly under beginner, intermediate
and fully manual flight modes. An innovative flight perimeter
fence and return to home functions provide bulletproof reliability
and ease of mind- flying has never been so simple.
Flight perimeter fence function: if the aircraft is in excess of
120m away from the pilot, the aircraft will return to home
automatically, with the pilot having the option of taking over the
controls at any time. Once over the home point, the aircraft will
circle at a 25m altitude at roughly 40km/h.
Return to home function: in the off chance that the pilot loses
orientation of the aircraft, the return to home function can be
triggered and the aircraft will fly back to the home point. Like the
flight perimeter function, this function does not take away the
pilots' ability to control the aircraft at any time.
Once over the home point, the Ranger 850 circles until further
control inputs are given.
Absolute beginners rejoice! The FMS 850mm Ranger has
everything that is needed for flight! A 12A esc/receiver combo
reduces the need to connect cables and a 2315-3850kv motor,
7.4V 850mAh 25c battery and four 1.9g micro servos give the
lightweight 305g aircraft incredible performance. Fly at a small
park, basketball court or even your own back yard!
The innovative 850mm Ranger is the perfect way to start earning
your wings!
