Hello! I have several old Ronin stabilizer models. None of them are in perfect working condition, however if someone is looking for an entry level gimbal or wants to try repairing them, I'll let them go very cheap. I have a RS4 pro with screws that I can't figure out how to tighten - the whole device will need to be opened up to access the loose screws.
I also have some of the older models that I don't use anymore. You're more than happy to try / test out the ones I have to see if they'll fit your needs. Super flexible on price - as I said they're not in great working condition but feels weird to just throw them away.
