hi, just a few mods ive done to my quanum v2's , most of them are ideas of my own , from the felt on the top and bottom inside of the goggles to stop the glare from the screen , the extended adjustment at the side for the fresnel lens , the camp bed mat 8mm foam on the sides to grip the lens holder better , the cut out for removal of the lens without taking them apart ;-) anyways, i hope this helps anyone new to fpv , as these mods help and make them so much better to use , the fresnel lens gets easily an extra inch and a half of adjustment overall this way, which is great if you have to wear glasses , it means you will always get your focus ....as they are originally, the lens at full adjustment is to close to the screen and does nothing that close , by the screen going to the front , that furthermost adjustment becomes useable , especially if you cut it more like i did..... give it a like chaps and chappettes ....
