Alexey Lantsov coaxial thrust system for F3P
Nova days almost impossible to imagine top class F3P model without coaxial thrust system. Benefits are obvious: torque moment of propellers are compensated so model makes left and right rolls precisely the same manner, torque rolls could be done both directions which is a must for final sequences. Airflow created by contra rotating props is less turbulent and all that allows to earn more so precious points from judges.
Alexey Lantsov made even more by combining outstanding flight characteristics with superb efficiency, lightweight and state of art engineering into one unit.
Alexey Lantsov coaxial system is probably most efficient F3P thrust unit in the market. Custom designed motor and propellers reduces power consumption to extremely low levels dramatically increasing flight time. This allows to use smaller batteries so saving weight and still have plenty of flight time reserve (Check technical information for more details).
Friction gear is not accidentally chosen by Alexey, having in mind that during thousands of flights in various conditions crashes happens even for most experienced pilots. When teeth s of simple gears tend to rip during crash, friction gear simply slips saving whole unit. Another important feature of Alexey’s friction gear is its quietness. Hard to hear motor whiz creates atmosphere of peace and full concentration in a hall. Who knows, maybe it could make positive impression on judges.
Every part of unit is designed lightest possible way leaving required margin of strength. This was possible only because of top quality materials used in production like CNC machined high grade aluminum alloys, titanium, carbon fiber.
Being state of the art equipment, Alexey Lantsov coaxial systems are very straight forward to use. Requires almost no maintenance and adjustment (only replace O rings of friction gear every few hundred flights). Just screw on, solder wires and ready to fly.
