It appears there's a bug in the rails with the current G2 version. This release will allow complete drone launch using the old style(just updated to rails). It's a shotgun type launch, all or nothing, right away immediate sort of thing.
In the near future I hope to complete a "rail shaker" that will knock loose any bugged out drones on the newer design. In the meanwhile this version will work just perfectly. =) thanks for the heads up on the bug guys!
