Always a bit sad to see someone leave the hobby, that said I've been lucky to get some parts extremely cheap this way, so can be a win for someone coming into the hobby and without the unlimited budget it seems to demand. Maybe worth putting some minimum prices on things or giving a will sell immediately for price (assume plus shipping).
Also maybe just don't like the platform but reminder ebay is a good place to get rid of some used stuff too sometimes and can get more attention than it would get here (is nice to pass along/sell to someone here too).
I crashed my Tarot due to pilot error while attempting an automated takeoff. I repaired it at considerable expense - new airframe, new 3 axis gimbal, etc.
I ordered a new set of Tarot propellers but it was going to take awhile to arrive from China, and so I was able to install a set using spares from previous mishaps. During its first post-repair test flight a propeller broke apart in midair and it crashed, destroying the airframe as well as the brand new gimbal.
I sorely miss building and flying my own multicopters, but there comes a time when you must cut your losse. I must pursue another, less expensive hobby: music.
Agree with others here, 5" or 3" even can still be a lot of fun and far less dangerous or likely to break itself, and you have a nice TX, would also say consider just taking a break on it (maybe still get rid of the mega components since can recoup some cash for small quads).
