| Model Tugboat Hull Kit |

For Radio Control |
| Manufactured by Vac-U-Boat™ |
This tugboat kit now comes with the new Vac-U-Boat 3-Blade Scale Bronze Metallic Plastic prop.
You can now purchase this hull in two configurations:
| TG100 Vac-U-Tug Jr. Complete Hull Kit. | A complete hull kit described below. |
| TG102 Vac-U-Tug Jr. Builder's Hull Kit. | All of the vacuum-formed plastic, piece of Velcro, set of decals, rub rail, and rudder-skeg assembly. A complete "exterior" for you to install your own drive system. |
It is easy for the novice to build the Vac-U-Tug, Jr. in just a few hours. The drive system is very durable and should provide years of service with very little maintenance. The H.I.P.S. "High Impact Poly Styrene" hull is lightweight and strong. It is trimmed by a rubber rub rail that will greatly reduce the chance of damage to other boats during a collision. At full throttle, it runs at a normal walking pace making it easily controlled by young children without the risk to the "adult toy boats" in the area. This is an ideal "first kit" for anyone new to scale model boating. At club meetings it makes a great visitor's boat because of it's long run times, slow speed and low maintenance.

New Deck Improvement: The deck now includes recessed trim-lines to cut out the rear hatch opening and the top of the cabin leaving a cleaner look and stronger openings. A small piece of clear plastic is included to cover the hatch opening. The rear hatch opening can now be secured with narrow tape to waterproof the deck yet give a window into the stern of the hull.
There is plenty of room inside for your radio gear and batteries. The motor is pre-installed in the removable motor tray. It draws only .45 Amp cruising at full throttle. With a two channel radio, electronic speed control & regular servo use, the total draw can average .76 Amp. With a new, fully charged 1,500mA 7.2 volt Ni-Cad battery, Vac-U-Tug Jr. will run for 1.5 to 2.0 hours! With this setup, about 29 ounces of ballast weight is necessary. This means that you can substitute heavier batteries or add electronic gear without overloading the hull. Oilite® bearings support the stainless steel prop shaft in a custom drawn brass stern tube. A tube of non-toxic, plastic-friendly Synco Superlube® synthetic grease is included for filling the stern tube. Our exclusive brass motor-prop shaft coupling uses an acetal plastic dogbone that has self-lubricating properties to minimize wear. The resin rudder is cast over a solid brass shaft and supported at the rudder arm with another Oilite® bearing. The motor tray & skeg screws are stainless steel. A DU-BRO™ E/Z Connector is provided to attach the stainless steel pushrod to the servo . The boat can be painted with standard "hobby enamel" short spray cans available at discount & hobby stores. To finish the boat, a set of outdoor sign-quality vinyl decals are included.

NEW RUDDER DESIGN NOW INCLUDED!
A new injection-molded rudder is now included in the tug kit. Shown on the left next to the original rudder, it has about 40% more area and will allow greater control in reverse. It can be sanded or trimmed to a more "scale" appearance if you wish. The shaft of the new rudder is slightly larger in diameter than the original. 0.124" verses the original's 0.123" to 0.1235" diameter. If you are upgrading an existing tug, you may need to use a 1/8" drill or hone to carefully enlarge the rudder bearing and the hole in the brass skeg in your tug to accommodate the new rudder. The new rudder (white part) is 1-11/16" wide by 2-1/8" high (at the shaft). Shaft is the same 3" length as the original. Matched/honed bearings for these new rudders are available if needed. Just ask.
To complete this hull kit, you will need: ADULT SUPERVISION, 2 ounces of 6 or 15-minute epoxy, medium CA glue, (Regular or non-toxic model cement will work fine but CA "super glue" is needed for the end joint of the rubber rub rail) electric drill with bit assortment, screwdrivers including a tiny Phillips screwdriver for servo screws, scissors, hobby knife or Xacto® knife, 29 ounces of ballast weights (a carton of 5,000 BB’s or lead shot work well), pencil, masking tape, light sewing-machine oil, two short cans of model spray paint or non-toxic type brush paints compatible with plastic.
To complete the radio-controlled boat, you will also need:
A two-channel AM or FM radio, (rudder & throttle), with one servo,
2.4 ghz radios are nice because there are no frequency conflicts with other transmitters. This is important if you are rescuing disabled boats.
You can use a two-stick model or a pistol-type radio like R/C cars use,
An Electronic Speed Control (ESC) with forward and reverse,
A "High Frequency" ESC will give you smoother low-speed control than a standard ESC.
A 7.2 volt rechargeable battery (six cells),
For a 20% boost in power, a seven cell 8.4 volt pack, (Recommended for tugs used for towing or recovery work.)
A 2s Lithium Polymer 7.4 volt battery will work well.
Or try a 3S 11.1 volt LiPoly battery for more power. Make sure your ESC can handle this higher voltage.
LiPoly batteries are dangerous to use and charge if you don't know how to work with them. Learn about them, use proper chargers, and use them in this boat at your own risk!
A Battery Charger. Inexpensive wall chargers will work
but "Peak Detection" chargers are best for your batteries.
