I started with some unnamed Drones then Tellos. (Have 3 of them & 1 fixer upper) Then I got a Phantom 3 standard ;-) have 3 crashed 1s & a 4 to that need work. Have 2 Rukos. (not much luck with them) Now got into the minis. there all used & broken 1 is bound I found out latter, & 1 is a demo I found out later. But can use the parts. so have a mini that I hope works & a mini 2se that needs a cam. & just fixed a mini 3 that I got working & crashed it. & fixed that today . I'm now much better at fixing tham flying. lol
