THE HUMMINGBIRD HELICOPTER KIT LEGACY
The Hummingbird 300L helicopter model is based on the S-52 helicopter. The S-52 model was FAA certified. The Hummingbird helicopter kit has been improved over the years and sells as an amateur build kit. The Hummingbird 300L is an experimental helicopter kit with wheeled landing gear, good for any type of surface (only found on million-dollar helicopters), has a cabin with plenty of space, for up to four passengers and of which we can proudly say that it is a safe helicopter.
WHAT MAKES US STAND ABOVE THE REST
Spotlight On Safety
Safety is what sets the Hummingbird helicopter apart from other experimental kit helicopters as well as certified designs. Thorough engineering and meeting FAA design standards makes the Hummingbird one of the safest helicopters available.
The following lists some of the extensive design testing completed on the Hummingbird;
- The fuel system is designed to the latest occupant safety and post-crash fire FAA regulations for Part 27 certified commercial rotorcraft.
- Transmission/Rotor containment in order to protect occupants.
- Seat mounting structure designed to collapse in the event of hard landing.
- Shock absorbing struts assist in the event of hard landing.
- Epoxy resins for composite components meet FAA fire resistant regulations.
- The firewall meets FAA Part 27 regulations.
- The fuel bladder is protected by 370 lb. puncture resistant liner.
- In the event of engine failure the blade pitch is automatically reduced to assist with pilot reaction time.
- FAA approved windshield & installation with wide area visibility, chin windows and sun roof.
- Lycoming aviation powerplant with excellent performance margins.
- Components tested to FAA standards for fatigue life substantiation.
- No mast bumping or flight restriction during maneuvers or wind gusts.

So ask yourself, do I really need a certified helicopter with all of the strings attached for the type of flying I enjoy when a Hummingbird offers the same or better engineering, safety, performance and costs. Fly anywhere with no restrictions. Build it yourself while learning every aspect of it, maintain it yourself, make changes with no FAA involvement. Bring back the fun factor!
Oh, and the Hummingbird has no 12 year calendar inspection or 2200 hour overhaul and no mast bumping!
