Towing
Towing with the Carbon Cub is only recommended
for advanced pilots. While towing, be sure to fl y in
a large, open space. Also be sure that you have
two pilots, one for the sailplane, and one for the
towplane.
The E-fl ite
®
UMX
ASK-21 sailplane is designed to be
towed by the E-fl ite
Carbon Cub (EFLU1180) from a
smooth runway. A tow line (approximately 28 feet
(8.5 m) long) is included with the UMX ASK-21 or is
available separately (EFLU1257).
Do not attempt to fl y or operate your ASK-21 any
longer than 25 minutes on a battery.
1. Position both aircraft near each other on the
runway, facing into the wind.
2. Tie the tow line to the tow plate on the
Carbon Cub. Tie the other end of the tow line
to the release mechanism under the nose
of the E-fl ite UMX ASK-21 (see tow release
installation section).
3. Space the aircraft apart so there is no slack in
the tow line. If there is slack, it can result in
damage to one or both of the aircraft.
4.
Ensure that the tow line is resting above the
Carbon Cub’s horizontal tail
so the Carbon
Cub can pull the sailplane into the air safely.
5. Quickly apply power to the Carbon Cub once
both pilots are ready for takeoff.
6. Keep the Carbon Cub on the ground until the
sailplane and is 2–3 ft (0.9–1.2 m) above the
Carbon Cub.
7. Slowly apply elevator to lift the Carbon Cub off
of the ground. Be sure to keep the Carbon Cub
under the sailplane until you have reached your
release altitude.
