Receiver Frequency Access

When you change to an aftermarket receiver you can often loose the ability to change radio channels without having to remove the receiver cover. However that can be easily cured as shown in the example below that uses my T-Maxx receiver box cover and my JR RS300 receiver. While the receiver box for the E-Maxx is different, this procedure can still apply to it as well.

The most important thing you need to do is to decide where the access hole should be located. You need to take into account factors such as the receiver's layout, where the crystals or channel switches are, and how it will be placed in the cover . Once that's determined the rest is easy.

In my case I drilled a 1/2 inch hole in the receiver cover so I could access the channel selection devices on the RS300. The reason I used a 1/2 inch hole, will be shown in the next step. Below is an example of what my cover looked like after this step was complete.

Now that a hole is in your receiver cover, without a method to cover the hole from the elements your receiver can possibly become damaged by any various number of liquids. You could simply use a small piece of duck tape to seal the hole, but I wanted something that had more of a factory look. I happened to have a spare plug from an Electric Stampede transmission cover. A 1/2 inch hole would allow this plug to fit, and would give me a similar look to the stock rectangular channel plug. Below is a picture of the plug installed in the cover.

The picture below shows the receiver as seen through the hole, which is what you would see if you were trying to change the receiver's channel.

Remember, the most important part of this modification is the planning involved in where to place to hole. Otherwise, you'll wind up with a receiver box that looks like Swiss cheese!!!
