VIABLE AND AFFORDABLE ELECTRIC AIRCRAFT IN 2015
But first: 3-1/2 Decades of aviation in 3-1/2 minutes
The 1980s: Ultralights Era
The 1990s: Microlights Era
• Moved to the Czech Republic
• Manufactured >500 Zenairaircraft
• Won Picolla Schnieder Cup Seaplane race 3 times
• Greek National UL Champion
• LOW SPEED
• LOW DRAG
• LOW WEIGHT

WHICH AIRCRAFT WORK TODAY ON ELECTRIC?
What works now?
4 of 5 Requirements to work:
• Low Speed
• Low Drag
• Light Weight
• Certification Standard
• Affordable
Unobtainum?
My Electric Plan:• Develop new aircraft-specific motor
• Cut propeller noise by 80%
• Develop safe and high power-to-weight ratio battery system and integration
• Design new PSA aircraft around electric power and certification constraints
OUR NEW MOTOR• Low rpm: 1,200 @ cruise power• Twin rotor for efficient cooling• Synchronous Axial Flux design• 3-Phase AC
• Custom design specifically for aircraft• Competitive pricing & available for OEM• 55 Kw theoretical power • 12 Kg weight
OUR NEW BATTERY SYSTEM• Carbon/Kevlar-sleeved cylinders for safety
• Flexible configurations & no heavy case
• Excellent cooling
• Cells are 65 Ah LiPo Cobalt and 3.7 volts nominal
• Lightest ‘total system’ in Kw/Kg on the market
• Integrated 350 Amp controller and BMS
• 2.5 hour recharge. 2,000 cycles
Safety is our priority!1. Cylinders prevent gas
expansion. Cell producer has zero failures.
2. Integrated BMS3. Cell cooling4. Battery Management
Monitor5. Pilot education

How about an Electric Amphibious Aircraft?How cool would that be?
Noise is just about the biggest problem seaplanes have and a seaplane with our electric system will be nearly silent!
An electric amphib that would sell for only $50,000!
This can become a reality this year!Our new amphibious float design is now finished.
