My name is Alex Kimmell. A friend and I have been looking at Ultralight aircraft, and are planning on building one. From what we know, all Ultralights have been built to be Monoplane aircraft with gas engines, but we would like to mix it up a bit. Dispite our age of only 13, we have undertaken the task of building a Electric Biplane to sail the skies with! Although, I am need of some help.
Our Original Plan:
Originally, we had planned on sticking two high torque electric motors and four car batteries in our aircraft, and varied the speed of the aircraft by switching the number of batteries supplying power to the motors, but through farther research, I am finding the plan a little impracticle.
I am looking for some help with finding some 12v batteries that are able to power two motors at a good RPM. I am also looking for two motors that can power an Ultralight Aircraft.
Our problem is finding the Motors and Batteries to power our aircraft.
Ultralight Aircraft Guidelines
These must be followed to build an Ultralight
Single occupant only for recreation or sport purposes with 5 gallons maximum fuel.
Unpowered free flight empty weight under 155 pounds or powered weighs under 254 excluding floats or safety devices.
55 knots maximum calibrated airspeed at full power in level flight, power-off maximum stall speed 24 knots calibrated.
Can be inspected by FAA to make sure it meets criteria as an ultralight.
Vehicle not required to meet any airworthiness certification standards
Pilot not required to meet any aeronautical knowledge, age, or experience requirements to operate or to have airman or medical certificates.
Not required to be registered or to bear markings of any type.
No operation is allowed that creates a hazard to other persons or property.
Only operate between sunrise and sunset unless equipped with a suitable anti collision light extending flight time to twilight periods 30 minutes before sunrise and 30 minutes after sunset.
Yield the right-of-way to all aircraft and not create a collision hazard with any aircraft.
Do not operate an over any congested area of a city, town, or settlement, or over any open air assembly of persons.
All operations are conducted in uncontrolled airspace unless prior authorization from the ATC facility to operate in within Class A, Class B, Class C, or Class D airspace, or within the lateral boundaries of the surface area of Class E airspace designated for an airport.
Must comply with flight restrictions in the proximity of certain areas designated by Notice to Airmen (NOTAM) and Temporary Flight Restrictions (TRF).
No person may operate an ultralight vehicle except by visual reference with the surface.
Visibility and cloud clearances similar to general aviation airspace.
If anyone could help me with this project it would be greatly appreciated.
