Bye bye balloons!
Ok, so I had my electronics in balloons to keep them all clean and hopefully dry, but the wires were a mess and I just wasn't happy with it, so I looked at how some of you other guys have stuff tucked away and water proofed. I liked the idea of the radio shack project box, so I went and bought one of those and started figuring out how I was going to make it work. Below is a pictorial of how I went about it. Hopefully it will be pretty water proof by the time I get all done. I plan to seal up the holes I drilled in it for the wires with some fish tank quality silicone.
Here is the inside of the project box. You can see where I took a dremel and cut out the four smaller mounting posts to make more room.
I planned to put the project box in the battery location, so I removed the battery mount and slipped the project box in between the body mount posts. It was a little tight so I took the dremel to the sides of the box where they hit the posts to make a little more room.
I used the battery mount as a template to mark out the mounting holes I would need to drill in the project box, then drilled away. I used the dremel again to taper the holes so the screws would sit flush. The original screws worked fine with the battery tray risers. I used shoe goo to attach the risers to the box, hoping it would seal up the 3 mounting holes. Also, you can see where I had to relieve the sides of the project box to clear the body mount posts.
Here's another shot of the mounted project box from the top at a little wider angle.
And here's a shot from the side. As you can see, I still have lots of room to lower the box and still clear the servo.
I started putting the electronics in the box. It's a tight fit and I had to be a little creative, but I wiggled it all in there. You can see the stock ESC with on/off switch, my Spektrum SR300, and most of the wires. I wasn't sure if I would be able to fit the light controller in, but I just put it on top of the RX.
Here it is with all the holes drilled. I drilled the smallest holes I could for each wire. I removed the plugs to make it easier (or possible) to the them through. For the light and servo plugs I just popped them off, slipped the wires through, then re-used the plug. The battery plug had to be cut off. The way routed the through the project box cover will make it a bit of a pain to remove the lid completely, but I don't figure I'll have to do that too often. And I soldered on a deans plug so it would be easy enough to remove if I have to and pull the batter wires back through.
And here it is with the lid on. Still need to find my silicone. Actually I was going to lower the project box, but I really don't want to pull everything back out! Bummer too, since now I have to just barely push the body down because it hits the very front of the project box. Guess I'll end up pulling it apart...so long story short, if you use this method, make sure you trim about 1/2" off the risers before you put your electronics in the box! :lmao:
And here is the (basically) finished product. You can see how much cleaner things are with all the wires tucked away. I just have to add the deans plug and fab up some sort of battery mount - you can see where I plan to put it here in the last picture.
I'm not sure how well the project box lid will seal, but it seems like it should be pretty water tight. Once I get the wire holes sealed up with silicone I should be fine as long as I don't dunk it completely.
Thanks to everyone here for all the good ideas! Next up, making my own metal links to replace the plastic ones. Actually, I did the lowers and steering tonight and took some pics along the way. I'll write that up probably tomorrow.
