What replacement parts should I keep on hand?

[Geoff]

Hey Geoff, you make any parts for the Cinetank?

Only leg extenders so far, or things people have sent me to replicate like the motor mount bottoms (a good crash seems to break that sealed black base pretty easy on the bottom of the motors) But not owning one limits you to what you can make of course...

The issue I have found with selling quad parts is simply fitting, nothing worse that printing something you don't own yourself only to find out the scale is off when the customer gets it, so I pretty much have stuck to making things that I myself have, so I can be 100 percent sure I wont be sending out replacements for anything, which I learnt the hard way of course. In fact, I had such a problem with some parts I bought the quad and/or flight controllers specifically for printing out parts, and not actually flying them, how crap is that!
