Blue-green algae produce two toxins, each with different symptoms. Signs of neurotoxin poisoning usually appear 15 to 20 minutes after ingestion. In animals, symptoms include weakness, staggering, difficulty in breathing, convulsions and ultimately death. In humans, symptoms may include numbness of the lips, tingling in fingers and toes, and dizziness.
Aeropro imposed the weight limitation so that the aircraft could comfortably meet ASTM stall speed requirements (a maximum of 51 mph) for Light Sport aircraft. The Aerotrek stalls at 43 mph indicated airspeed with flaps down and 49 mph with flaps retracted. Trim and flap levers (left inset) are easy to reach. The trim is the shorter lever, while the longer flap lever moves through its full range without detents.
