I've lost my DJI Mini 2 drone around 3 days ago. I could not retrieve it. I'm planning to buy a secondhand dji mini 2 drone only without controller. Will it be possible or can it still be connected with my existing remote control? Thank you

The mini 2 has been superseded by  the Mini 4k-the Mini3, Mini3pro, and the "SE" would also work on your RCN1 controller....and  in my experience, the cost  of some of these be the same or less than trying to find a brand new mini 2, but either, Yes, IF the  drone is "unbound". Ie: a brand new one from DJI being the very,very best bet...

    A used one is problematic and I would not buy one without personally being with the seller to bind it to my controller before buying it.

Thanks for this insight mate. I do really appreciate it. As for now, I'm trying to negotiate to buy just the aircraft for mini 2 and hopefully, this will work well in my existing controller from my lost drone.

It will, but again- for a used drone, I definitely recommend personal contact-binding and linking it and testing before buying. There are so many posts here where people are struggling to get a second-hand drone unbound  from a previous account.
