2-1. Radio Operation
2. Start Up Guide
1. Switch the radio on and make sure the power indicator light turns on and the
radio beeps once. If this does not happen, check to make sure the batteries
were installed correctly. When the battery level in the radio becomes low the
radio will begin to beep, signaling you to replace or recharge the batteries.
Note: The 3 Speed Toggle ranges from fast, moderate, and slow.
When operating the tug at slow speeds it may be neccessary to
switch to the moderate or fast speed position on the toggle when
turning at 90 degrees. Factors such as terrain and incline may
affect the maneuverability of the tug.Adjust the speed at your own
discretion.

2. Start Up Guide
Warning: The control stick on the remote is very sensitive and will cause
the tug to move if it is moved accidentally. When not using the
remote it is recommended that the power switch is turned OFF.
Note: If the remote is not used for more than a couple minutes it will start
beeping as a indicator that it is still in the ON position. This is not an
indicator of a low battery.
2. To drive the tug, move the control stick in the desired direction.

2-2. Operating the Tug
2. Start Up Guide
1. Before turning on the tug, make sure that the tracks and bottom of the tug are free
from obstruction.
2. Turn the tug on using the ON/OFF button. There will be a short series of beeps and
then the power indicator LED around the Power button will illuminate to show the tug
is on. The Power Indicator LED will blink to indicate the charge level of the battery is
low.
3. Turn on the power switch on the radio controller and the power indicator LED will be
green and the transmit indicator LED will be red.

Check for proper seating and alignment.
5. After lifting the tug off of the ground for any reason or taking it in and out of your
aircraft, you must check to make sure that the sprockets are correctly seated on the
tracks. If the sprocket is not properly seated it could result in damage to the tracks.
6. Visually check the tracks for wear on the treads and wear on the inner plastic surfaces.
Also inspect for damaged or missing rotoclips as a result of driving over small rocks.
Damaged treads should be replaced before operating the tug.
Note: The circuit breaker reset button will trip if the tug is overloaded. To reset
the circuit breaker open the top cover to push the reset button down. If the reset
button pops back up wait 1 minute then try again.
4. When towing your airplane ALWAYS be cautious of the steering angle limitations of
your aircraft. Do not oversteer your aircraft with the tug. This can cause damage to
your gear.

2-3. Adjusting The Wheel Cradle To Your Tire
1. Remove the link locking pins from both sides of the wheel cradle and position
the cradle in down position as shown below.
Link Locking Pins

2. Place wheel chocks behind the rear tires of the plane to ensure the plane does not roll
backwards.
3. Drive the tug under the wheel of the plane until the wheel cradle locks in the upright
position. Make sure the wheel is touching the back gate as shown.

Push this side
up towards tire.
4. Push the front side of cradle until it is touching the tire and reinstall the pins.
If pins cannot be installed while the front side is touching the tire, move the
front side of cradle away from the tire until the pin can be inserted into the
next closest hole. You do not want this to be too tight on the tire.
Do not force the adjustment pins in.
5. Release the latch using the radio and back the tug out from under the plane. Drive the
tug back under the tire to check that the wheel cradle is set up correctly and to ensure
the cradle is latching securely. When releasing the latch always make sure the wheel
is against the back gate. If not, the latch may not release properly.

2-4. Adjusting The Dovetail Spacers To Your Tire Adjustment Pin
Dovetail Spacer
1. If the dovetail spacers are in the furthest back position and your tire does not fit or it is too
close of a fit remove the dovetail spacers and adjustment pins.
Furthest Back Postion

2. Adjust the dovetail spacers by removing the adjustment pin and sliding the spacers
towards each other. Ideally the dovetail spacers should be moved the same distance on
each side to keep your tire centered in the cradle. The distance between the dovetail
spacers should equal the width of your tire plus one inch maximum.
Width of your tire
plus 1” max

Spacer
3. Align each dovetail spacer to the nearest hole in the dovetail guide. Insert the adjustment
pin in either one of the two aligning holes on the dovetail spacer. The cradle might limit the
access to one of the aligning holes therefore insert the adjustment pin into the aligning
hole that is easily accessible.

2. Start Up Guide
2-5. Adjusting The Track Tension
Track tension may need to be adjusted after several hours of use.
Follow the instructions below for each track.
1. Remove 6 track cover screws and remove the outside plastic track cover.

2. Loosen the three front rail end retainer screws. It may be necessary to rotate the large
sprocket in order to gain access to one of the retainer screws.

3. Push the rail end forward using a small pry bar to add tension to the track. There should
be about a 1/2” of play at the center of the track.

2-6. Loading The Airplane Wheel Onto The Tug
1. Turn the tug power ON and the radio power ON.
2. Use the latch release switch on the radio to lower the tire cradle
3. Drive the tug to position it just in front of the wheel.
(Some tail draggers can be approached from the front or the back
depending on the wheel configuration)
4. Drive the tug under the wheel at a moderate speed; No need to get a running start.
5. The wheel will roll up onto the tug and will push the back gate of the cradle to the
latched position.
Note: It may be necessary to apply a little pressure with your foot to the top of the battery
cover to get the wheel started onto the tug.
6. Drive the tug in the forward or backward direction to maneuver the airplane to its desired
location. Be cautious of the steering angle limitations of your aircraft. Do not oversteer
your aircraft with the tug. This can cause damage to your gear.
2-7. Unloading the Airplane Wheel Off of the Tug
1. Turn the tug power on and the radio power on if not already on.
2. Push the tug slightly forward so the airplane tire puts pressure on the back
gate of the cradle. The back gate is the gate that is closest to the latch mechanism
3. While holding a slight pressure on the back gate release the latch by holding the latch
release switch on the radio.
4. While still holding the latch release switch move the tug away from the tire.
5. The front gate should go down and the airplane tire will roll out of the cradle.

2. Start Up Guide
2-8. Charging the Tug
1. Before charging your tug, be sure the radio and tug are both turned OFF.
2. The charging indicator light on the charger should light up red once the charger is
connected properly. The tug will be fully charged once the charge indicator light turns
green.
It is recommended to leave the tug charging when not in use.
3. Once the tug is fully charged, unplug the charger and turn the tug on. Then turn the tug
off for a few seconds and back on again. This will reset the tug. It is now ready to be used.

2-9. Charging the Transmitter
WARNING: Only use the supplied charger to charge the transmitter when using the
supplied batteries or the following:
- 1200mAh Ni-MH or Ni-Cd ‘AA’ Rechargeable Batteries
The use of the transmitter charger with alkaline batteries installed can damage the
transmitter. Do not use the charger if alkaline batteries are installed in the transmitter.
1. Plug the transmitter charger into a 110v AC wall socket.
2. Plug the connector from the charger into the charging jack on the transmitter. The
charging indicator LED, located on the side of the transmitter, will illuminate green
indicating the transmitter is charging. Once the transmitter is fully charged the charging
indicator LED will turn off.
3. The charging rate of the charger is 150mAh. When using the 1200mAh batteries that are
supplied, the radio requires a 2-4 hour charge when fully discharged (1200/150=8). If us-
ing 2200mAh batteries, it will take approximately 4-6 hours ro recharge (2200/150=14.6).
It is recommended to keep the transmitter charging when not in use.
