Hey WakenBake - What are you flying? Running Iris+, Solo & DIY here...don't be a stranger!
There is a newish camera/gimbal folks are starting to run from SIYI - I don't have details but if you're on Facebook or know someone that is there is an active group of Solo experts and users that are extremely helpful.
The SIYI A8 Mini is a good gimbal/camera option for the Solo. There's an easy installation kit for it in this store, and lots of other upgrades and options. Even fully ready to fly Solos are available here.
