I purchased myself an FC40 for Christmas. I love it and have been having some fun in between rainstorms. [youtube]https://www.youtube.com/watch?v=9z2Vt2H4Jp8[/youtube] Questions I have: 1. I really would like OSD to know how high I am. I am looking at the http://www.goodluckbuy.com/fpv-flight-c ... e-gps.html, but do not have experience soldering to boards or the like. Is it plug and play? 2. Gimbal, I want a gimbal. Are they easy to install or should I have bought a Vision +? 3. SJ400. I would like to add one of these to my setup, anyone have comments on the quality?
