A few basic questions. I am currently considering buying an extender and know very little. 1. Which range extender(s) is/are currently available for the P3 4K? Please include a link. 2. Does the improved range also allow for longer FPV range, or will FPV cut out at the same distance as the stock transmitter? 3. What type of range will I get with the extender? 4. Difficulty of install? Also, are there any online tutorials on how to do this for the 4K (aside from the one I found that's in Chinese)? Thanks!
