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.
The Eurofox is sold in Europe as both factory complete and kit form, but is only available as a factory built aircraft in the U.S. From 2009, the Eurofox models were marketed in the USA and Canada by Aerotrek Aircraft of Bloomfield, Indiana.

Both versions are offered with the 80 hp (60 kW) Rotax 912UL and the 100 hp (75 kW) Rotax 912ULS engines.
