Landing Gear was from Ebay - it's not great and I have since taken it off!
I bought the carbon fibre landing gear set that's on ebay (made by Tarot) and it weighs nothing - taken that off now though also as i've taken all the camera stuff off the 450!
The lid is simply a tupperware that I cut down and then re-gluded to make it less deep.
Keeping the KK2 away from harm and any moisture in the air is very important. I killed the KK2 on my 330 after flying it upside down into the grass
