I placed an order a few weeks ago for one. but I'm on the fence about canceling.
I've had to deal with these 510 issues on my cuboid. Didn't want a repeat. But then again, it was only 40 for the unit.
How easy is it to replace the 510 on the rx200/s?
Use the link below as a rough guide. I replaced both my RX200 mods with FDV 510. I never really had an issue with the original 510 until I got the Gemini which has an awkwardly long 510. I ran a home made spacer by cutting a gift card for a while because I was too lazy to replace the 510.
The battery tray does have to be cut to fit the 510 negative nut. Once you open the battery tray you will notice the top battery terminals. I used a dremel to cut just enough to retain the button holders. Sorry but I did not take any pic, but you will understand what I mean when you open it.
Replacing the 510 in an RX200... Fairly easy actually.
