First of all, for a first dive, what a blast! This thing is way too much fun. Here is the video:
So, a few issues.
The feed to the ROV is a bit choppy. Would lose video and controls for a second or two every 30 - 50 seconds or so. Not sure whats up with that?
I have had ZERO luck with the Teflon tape sealing the tubes. Diving to about 20 feet was okay. We did a much deeper dive to about 60 feet and brought it up quickly. The electronics tube had about 1 inch of water. Bummer! Dried it all out, esc's lost programming, but everything still works fine. Whew.
I then decided (as I had brought some) to use the rubber balloon trick mentioned in another post to create little gaskets under the main rubber o-ring that seals the tube. This works like a charm! I recommend only using this. Cut them just wide enough to fit nicely in the groove where the rubber o-ring goes and it seals the tube very tight. We brought it back down about 40 feet with no more leakage issues. I wouldn't cut them wider than the grooves. I did that on the battery tubes and the caps were almost impossible to get back out.
All in all, more than a success. I have some more desiccant packs in the mail and plain another dive this weekend. Going to shorten the tether a bit as we wont be taking it down over 100 feet.
Obviously some weight distribution issues. I had it a little negative buoyant so I had to remove a weight which threw off the balance.
One other issue, as "shift" is ascend, when you hold it down or press it a lot, it keeps asking me if I want to turn on sticky keys... any way to assign this to a different key?
