I had the same idea of using the metal tape. But, I performed a simple test first. I wrapped my cell phone with a layer of cooking aluminuim foil and tried to call my phone. The phone started ringing. Tried two layers of cooking aluminuim foil and the phone could not recieve a signal when I tried to call the phone.

Next, wrapped the phone with a single layer of the metal duct tape. Call the phone and it ringed. Crap. The metal duct tape is a lot thicker than the cooking aluminuim foil. I would estimate that the metal duct tape is the same thickness as three layers of cooking aluminuim foil.

Tried a double wrap of the metal duct tape. This is approx same thickness as 6 layers of cooking aluminuim foil (I estimate). The phone ringed. So, I decided that the metal duct tape is a FAIL for interefernce protection.
Awesome test, thanks

What about adhesive copper foil tape?

Allot of music shops sell it so you can shield the back of guitar pickups makes for a cleamer sound.

i bought some from amazon

im sure copper would work better than aluminium foil

i also have all the gps mounting on velcro per another persons suggestion and it works fine. i can easily adjust to get rid of toilet bowl
I was curious if the GPS was any more or less sensitive to the GoPro 3 than the GoPro 2? Or are they about the same.

Seemed about the same, each would cause loss of GPS signal when in close proximity to the antenna

Testing out the new green vibration pad from vibrationmounts.com. I went from horrible jello-filled 1080p using earplugs to crystal clear 1080p using the green vibration dampening pad. These things are expensive but worth every penny (especially if you have a friend that is willing to split the cost with you).

I've had success with fairly inexpensive dubro foam rubber from the LHS. Here's some of my footage from over the weekend.

Looks good. And a hell of a lot cheaper than the green vibration pad. May have to pick some of that up for the frakenquad I'm going to build this winter.

Do you mean this one? You weren't kidding about the cost but the video looks great. I've had pretty good luck using the foam earplug method... it's not perfect but it drastically reduces the vibration.

**edit** I've also tried Moon Gel but didn't have much luck with it.

Actually , this is the one I use. The web page shows a blue one but the bottom of the page gives you different options. The green one is supposedly tuned to the types of vibrations produced by motors in the 900 kv range. $90 is steep though. The pad is big enough for 2 gopro cameras though so you could split the cost with a friend.

If it still works, sand the scratches and paint it. I do not think you will be able to find a replacement unless someone has one that is dead.

I was going to say... the scratch shouldn't affect the operation, correct? If it works, the scratch is cosmetic. But if that's not good enough, then yeah, sand it down and paint it. I'm not aware of just the cover for the puck being available for purchase.

Battle Scars

As long as they don't look like my cat chewed them, I like to leave my dents, dings, scratches as is.
The airframe looks like it's well broken in, and not babied.
The white finish on My GPS has the black plastic showing through in a couple of spots.
A nice, shiny, new looking rig is nice, but it won't stay that way long if you plan to fly it.

Based on testing I recently did trying to debug a new Naza (which turned out to be bad), I'd say you're fine testing without ESCs connected.
You're getting communication since you see 3 reds & 1 green LED flash.
I'd try another location to test GPS.
Remember that you pretty much need open sky above and around your test site.
Finding GPS satellites won't happen if conditions are marginal.
