I've got the whole Trex 500 series from ESP Flybar to X, but except the Pro version. If I'm remember correctly Pro is the very first version with Tail server mounted "In Frame", body is slimmer and bigger than early version. After this the L version than introduced Battery mounted "In Frame" concept, Pro still mounted the battery out frame. So Pro body frame is not compatible with any of the before and after version.
If you're not a technical man, strongly recommended not to get any model before L version, because they all have serious mechanical design problems on body parts, all my old models have been modified in order to get max server's travel for extreme

maneuver fly. That's why Align upgraded the model to L version with the new server mount concept to reslove the issue which has caused server burnt to many flyers.
