First budget build starting from something i already have

//Crosspost from fpv drones weekly megathread​HI all,As my first experience i wanted to build an Eachine Tyro129, because it's really good value. I'll try my best at soldering etc.If correct, my complete gear setup will consist of:Turnigy 9x (already owned) + FrSky module (to be installed) + original firmware(?possible?)Tyro 129 (GPS module and vtx incuded) + FrSky XM plus receiver (or a no solder alternative)FPV with eachine 800DM gogglesI want to be able to do RTH and osd with: speed and altitude, is this setup ok? I've learned that the XM plus receiver is able to do telemetry on it's own...Considering that i already own the Turnigy 9x (no receiver) from the list above, i wanted to know if there are "less or no soldering" almost equal alternatives to the shopping cart above, without going much higher with the budget.​Thanks IN ADVANCE via /r/drones https://ift.tt/3aNvJwV
