Mosquito Personal Helicopter

ROTOR F/X is pleased to offer the exciting line of ReadyBuilt™ Mosquito ultralight and experimental helicopters with a complete range of choices and five different models to meet any budget or technical quest.

We are here to support your quest for vertical flight with these superior kits, builder assist services, ReadyBuilt systems, parts, service, setup, flight testing and flight training.

Personal vertical flight is now within your reach – choose your dream from any of the five models below.


Mosquito AIR – For simplicity and pure “out there” flying  experience consider the Mosquito Air. This is as basic and thrilling as it  gets, cruising over the landscape below with little to obstruct your view or the exhilaration of the wind rushing past. This pure fun ship can be flown under FAA Part 103 ultralight rules and does not require aircraft  registration or pilot license*.  No Pilots License Required To Fly This  Helicopter In USA**


Mosquito XEL – When your preference in a Part 103 ultralight requires more of a standard fuselage and cockpit then the XEL will meet your needs. The integrated fuselage standard to all XE models forms a most pleasing and aerodynamic shell with all the required instrumentation and comforts a recreational pilot might want. The included safety floats provide an exemption to the standard 103 lb weight limit to keep this beautiful ship within the ultralight category. This helicopter can also be flown under FAA Part 103 ultralight rules and does not require aircraft registration or pilot license*.  No Pilots License Required To Fly This  Helicopter In USA**



Mosquito XE –  If you have a rotorcraft rating or are planning on getting your license the XE is the place to start. Identical to the XEL but without the floats and with an unrestricted fuel capacity the XE will really take you places. Fly for over 2 hours, or even 4 with optional extended tanks, at a comfortable cruise of 75 mph and a very economical fuel burn of only 4.5 gallons per hour. This helicopter requires FAA registration and a pilot rating with its enhanced capabilities.  Helicopter Or Fixed Wing Pilot License Required To Fly This  Helicopter In USA**



Mosquito XE285 –  Additional power is the prime feature of the XE-285 helicopter. Identical to the XE in all other features, the XE285 boasts a power increase of over 30% for higher performance, a larger load or high altitude performance. You’ll also experience a rated cruise speed increase to 85 mph and a significant jump in rate of climb capability. As with the XE this helicopter requires FAA registration and a pilot rating.  Helicopter Or Fixed Wing Pilot License Required To Fly This  Helicopter In USA**



Mosquito XET Turbine –  This is the ultimate experience in performance, technology and pure “wow” factor. With a top speed over 100 mph and rated climb rate of 1,200 feet per minute this performer will satisfy the most demanding pilot and turn heads and gather crowds wherever you travel. There is nothing like the pure power and sound of the turbine propelling your helicopter into performance parameters all others will envy. The turbine engine is additional on this ship and engine cost typically ranges from $10,000 – $15,000 depending on configuration and options.
