What kinds of testing have been performed on the Ultrasport 254/331/496?

When American Sportscopter built the first two prototype helicopters, we instrumented the rotor blades, pitch links, control system and rotor shaft with strain gages. A 20 channel data recording system was installed, along with a slip ring, and 5 accelerometers on the airframe of the flight test helicopter. An experienced test pilot then performed a full flight test, and we gathered and analyzed the flight loads and performance data. We know the loads that each component in the dynamic drive train and rotor system is subject to under the most demanding flight conditions. We have applied several factors to these loads in our production design, ensuring you will not reach a load limit of any component when flying our family of helicopters. All flight critical components are built to the same quality standards as components produced for the major aerospace helicopter companies. All are specially designed and manufactured for the Ultrasport helicopters. No off-the-shelf automotive or uncertified hardware is used in our kits.


What if I live in a high altitude area?
The 331 & 496 are now available with Fuel & Oil Injected Engine  with are self compensating for altitude. The fuel system is pressure altitude compensating. 

What about maintenance and service?
  • Engine: Overhaul at 500 hours
  • Rotor Blades: Infinite life
  • Most other metal items: Inspect and grease as needed every 50 hours. Replace on condition. (R.O.C.)
  • All components wre designed for reliability and long life (i.e. 1,000 hours of more)
What about warranty of parts and parts availability?
One year warranty of parts. Airworthiness of the aircraft is the responsibility of the kit builder. There is a new Ultrasport distribution facility in Newport News, VA, USA which has good inventory of all Ultrasport kit items. Engine spares are available through the Hirth distribution network or Light's American Sportscopter inc.

Can I transport the Ultrasport by trailer? How far can it be transported with the rotor blades and tail boom assembled?
Yes, we recommend supporting the tail boom for extended trailering. we recommend removing blades if trip is more than 50 miles. Further info contact LASI.
Where can I find financing for Ultrasport helicopters?
We recommend contacting NAFCO Finance company in Lakeland, FL USA at (941) 644-8463. NAFCO specializes in financing for homebuilt aircraft and ultralights.

Is insurance available?
The Ultrasport insurance program is through Caledonian Insurance in Mercer Island, WA USA. The program covers hull value and $1,000,000 of liability insurance. Contact Caledonian Insurance at (206) 232-9870.




How long does it take to assemble a Ultrasport Kit?
It will take about 250 hours of work for an experienced person to complete the assembly. If you have never assembled a kit aircraft before, it will probably take you up to 200 hours of work after thoroughly reading and following the Assembly Manual which includes painting etc.

Do I need a helicopter pilots license to legally fly the Ultrasport?
  • 254: Technically no because it is an ultralight, but you will need training time.
  • 331 and 496: Yes

What will I do for my aircraft first flight testing?
If you are the firt time builder, we suggest that you can find the FAA Flight Test Handbook(Advisory Circular No:90-89A) at http://www.fedworld.gov/pub/faa-oai/90-89a.pdf to help you developing the flight test plans.

What are the Ultrasport safety features?
  • High inertia rotor system for excellent autorotaion characteristics.
  • Large deflection landing gear for safe and low CG landing loads.
  • Wide skids for high resistance to static and dynamic rollover.
  • Shrouded ring tail for personnel protection in vicinity of tail rotor.
  • Ballistic Parachute is a plannded option on the Ultrasport 496.
How long do I have to wait to receive an aircraft once it has been ordered?
