Waterproofing your RC Rock Crawler with Ease

Remote controlled or radio controlled vehicles were first in presented during the late 1960’s by an Italian company which specializes in toy cars. Right then and there, car enthusiast flock to get a glimpse of the first ever radio controlled toy car which made the headlines. Since then, a bunch of other models came to being. From then on, other countries replicated the said toy vehicle and somehow made a better version of the innovator’s creation. Countries like the USA, China and Japan joined the trend in producing the popular invention.

Today, with the help of technological advancement, radio controlled toy cars reached a new high which is now being called as Rock Crawlers. These rock crawlers are exact replicas of monster trucks which are of course still battery-operated but is driven to challenging terrains such as rocky mountains and even running waters in small rivers.

Though highly capable, radio controlled rock crawlers can be driven through teen uneven surfaces but the most challenging part it will face is crossing through surfaces with running water. This is quite difficult as the electronic parts of the rock crawler is not waterproof so when it comes in contact with the batteries, the servo or the wirings, the entire machinery, no matter how advance will come to a halt. A struggle that has made rock crawler owners exhaust other creative ways to solve their dilemma.

With several tries, some rock crawler gamers discovered the secret how to waterproof RC Rock Crawlers and to creating a waterproof radio controlled toy. And to help all you beginners out there, Here are some of the widely used methods in doing so.

The first approach is what we call the containment method.

Basically, what we ought to do is to have the non-water proof parts of the rock crawler, such as the receiver and the electronics main control, boxed into a compartment. And the materials we need to have are a clamshell box-preferably transparent in presentation to allow the user to check for the parts inside the box every now and then, an electronic driller and water-resistant silicone glue.

The main goal is to place the receiver or batteries inside the clamshell box for the batteries to be safely kept from water contact. The box must allow the batteries, including the wirings, fit snugly to avoid taking up too much space inside the rock crawler.

  •  So First and foremost, you need to puncture the side of the sides of the clamshell box to provide an entry point for the electrical wirings. To do that, you need to carefully punch out some holes with the use of the electronic driller-about one to two holes will just be enough.
  • Then you side the batteries inside the plastic casing and cautiously insert the wirings right through the holes and make sure they are all aligned properly.
  •  Close the box and now you are ready to seal the case.

To be able to do that, grab a silicone glue and gently squeeze it out, applying it evenly to the areas of the box that need to be sealed such as the opening of the box and the puncture holes on the sides.

  • After applying, allow the silicone glue to dry up then add another coating to make sure that the case becomes water resistant.
  • Then just place the box inside the crawler and you are good to go.

The next strategy in waterproofing your rock crawlers is the balloon technique.

This is one of the most conventional ways of preventing water from coming in contact with the rock crawlers. And the things you need to have are zip ties and medium-sized balloons.

  • Primarily, you must place the batteries inside the balloon.
  • After suiting up the batteries, pull the mouth part of the balloon to cover the wirings then carefully pinch the lower portion of the balloon’s opening then twist it to tighten its hold towards the wires.
  • Then, insert a zip tie to the twisted part of the balloon and lock it up to totally seal up the balloon.
  • And if you are feeling a little insecure, you can add up to two more zip ties beside the first one then cut the remaining portion of the zip tie. And that is it. Your Rock crawler is ready to catch little waves in the river.

Another technique is to use plastic dips to prevent damaging your rock crawlers resulting from water contact.

The pieces of stuff you will need are a thin metal wire and a plastic dip.

  • The first step is to attach the thin metal wire on top of the batteries, make sure it will be able to hold its weight and will allow you to remove the wire after the whole process. This will serve as a device to pull up the batteries out of the plastic dip.
  • After attaching the wire to the battery, you can now submerge it to the plastic dip. Once fully covered, raise the battery and allow the plastic to dry up.
  • After which, dip the battery once more and do it for about two to three times more. Just make it a point to include some parts of the battery’s wiring in the plastic dip.
  • After drying up, remove the attached metal wiring, and then it’s done.

Lastly, there is another way to prevent water from destroying the important parts of your radio controlled rock crawlers and that is with the use of grease-lots of grease. This is a non-traditional way of waterproofing your rock crawler. What you need for this method is a can of grease, an electrical tape, and a screwdriver.

This method is advisable for the servo of the rock crawler. The first thing to do is to open the servo using a screwdriver. After removing the screws, place a generous amount of grease inside the servo as the grease is waterproof. After doing so, place the lid of the servo and wipe off the excess grease from the body of the servo. Then attach the screws back in its place then that’s just about it.
