O.S. ® 1.60 FX Ringed Engines
OSMG0660 1.60 FX Ringed with Muffler
OSMG0661 1.60 FX Ringed without Muffler
Weight Without Muffler: 32.6 oz
Practical RPM Range: 1,800-10,000
BHP @ RPM: 3.7 @ 9,000
The 1.60 FX features dual ball bearings for durability
and smooth operation, plus a low crankcase profile
that allows for a proportionally taller, semi-squared
head - a design refinement that increases cooling fin
area and improves heat dispersion. The threaded
portion of the crankshaft is extra-long for more
secure prop and spinner nut engagement, and the
needle valve is remotely mounted for safety during
adjustments. The high-speed needle can also be
mounted horizontally, vertically, or separate from the
engine for more installation options! Both styles
include glow plug and 2-year warranty.
Futaba ® 9C Super Computer Radios

Enjoy 9-channel PCM and 8-channel FM capacity,
easy programming–and with the included 16K
CAMPac module, the memory capacity for a whopping
18 models! The 9C’s up- and down-timer has a third
function that keeps track of total flying time for any
particular model. Besides Basic offset trim, there are
three other glider offset trims to choose from. With a
selectable switch through channels 5, 7 or 8, you can
set up a 2-rate or 3-rate GYA gyro system for your
airplanes. Plus, the heli mode’s Throttle and Pitch
Curves feature a delay that smoothes the transition
from hover to idle-up. Comes with full NiCds, and is
available in FM and PCM modulations.
