If your hex wrenches are unlabeled (or you wore the labels off after a bunch of bench sessions), and you keep grabbing the wrong wrench, just wrap a band of colored plastic tape around each handle so that you can easily tell which wrench is which. The tape also comes in handy for labeling spark-plug wires on your full-size car, stereo and TV cables, you name it.
To achieve airbrush-like results and reduce overspray, just spray ordinary RC paint into the large opening of a small funnel, and a narrower stream will come out of the small opening. Don?t forget to wear a particle mask when you paint.
You can extend the time between air-filter clearnings by putting first-aid gauze around the prefilter. It’s available in several widths and lengths, but the 2 1/4-inch wide roll works best. Wrap the gauze around the air filter a few times and tuck the end under the air-filter end cap. When it gets dirty, tear it off, and replace it with a few layers of clean gauze.
The nose section of the Mini Inferno buggy body can break off easily if you aren’t careful when you remove the body. If the nose piece breaks off, glue it to the front gear cover with Shoe-Goo. The nose piece will stay on when you remove the body, and it can be easily peeled off if you need to open the gearbox.
Use the fine plastic automotive-body repair mesh (available at most automotive supply stores) to prevent debris from passing through the cooling holes in your nitro vehicle. The mesh is easy to glue to the inside of Lexan bodies. Cut pieces that are slightly larger than the holes, and glue them inside the body and over the holes with CA.
You can easily build an onboard glow igniter using a single sub-C rechargeable battery cell and a few simple, inexpensive parts. First, solder a battery bar to each end of the cell, and strap the cell to the chassis in an easy-to-access location. The battery bars will give you a spot to which you can attach leads from your charger, so you’ll be able to recharge the cell without removing it. The next step requires a section of wire, a crimp connector and a small, two-prong, momentary pushbutton switch from RadioShack. Select a crimp connector that fits snugly over the electrode end of your glow plug but can also be pulled off when required. Crimp one end of the wire onto the connector, and solder the other end to one prong of the switch. Solder another length of wire from the other prong, and attach the other end of the wire to the positive end of your cell. Finally, solder a length of wire between the cell’s negative terminal and the engine block. It is easiest to use an eyelet connector (also from RadioShack) and attach it to any steel screw on the engine. This wire will serve as a ground and will complete the circuit. Now, when you want to start your engine, just hold down the switch while you pull the starter cord or use a starter box. You can even wire 2 cells in series for more voltage and starting power.
The O-ring seals fit tightly inside the RC18T’s shocks, and pushing them into the shock bodies can deform them and cause binding. Install a shock shaft (with the piston in place) through the shock body, and then slide the two O-rings over the shock shafts. Slide the O-rings all the way down the shaft and into the opening in the shocks. This will ensure that the seals are installed correctly.
Oran syringes work great for measuring 2-cycle oil and putting it into your gas vehicle’s fuel container. Most hold 2 teaspoons of liquid, so it’s easy to calculate how much you need: 2 full teaspoons equal 10cc, so if your vehicle requires a 30cc mix for every gallon, use 6 teaspoons of 2-cycle oil in every gallon.
There’s no denying that the high-end soldering irons deliver the best performance, but you can improve your inexpensive pencil-tip soldering iron. Use a hacksaw or Dremel tool with a cutoff wheel to remove about half of the tip. The modified iron will heat up faster and get hotter. After you?ve cut the tip, use a file to re-create a pencil or spade tip?whichever you prefer. Wear safety glasses during this modification and make sure that you unplug the soldering iron before you start to cut.
