Very high torque motors capable of spinning very large props
in sport aerobatic models of 10-12 lbs. and sailplanes up
to 16 lbs. These are larger and more powerful than the 4120
series motors. These motors weigh 14.42 oz., are 49mm (2")
diameter and are 65.5mm (2-5/8") from back to front.
The hardened 6mm shaft is supported by 3 ballbearings for
a long service life. These motors can be mounted behind
a firewall or, with the addition of the Radial Mounting
Set, they can be mounted in front of a firewall, particularly
useful in some glow-to-electric conversions.
