O.S. have long made engines for R/C
helicopters and built an amazing reputation
in that market for power, precision and
durability. It was therefore logical to offer
customers an electric alternative for
that emerging need. The motors here are
intended for helicopters in the 600 class
and have carefully chosen kV options to
suit the popular helicopters on the market.
Each motor is of course CNC machined,
fully ball raced and with particular attention
to cooling by careful internal design and
an effective, integrated fan. As usual, only
the best materials are chosen for the O.S.
motors to ensure a long and trouble free life.
Would you expect anything else from O.S?
• CNC Machined Case
• High Power Magnets
• Integral Cooling Fan
• Pre-Fitted Connectors
• Fully Ball-Raced
