I haven’t used this company so I can’t speak to the quality of their work, but they claim to be a legal firm that provides service, and other, contracts for drone service providers.

For anyone that needs a tablet extension mount for their Cendence RC, I purchased the Aboom Tablet Extension Bracket that was designed for the Phantom 4 for $8.00 and it fit my iPad Pro 11 perfectly into my M210 Cendence RC (see images)...
I have the standard tablet mount that comes with the M210 (see image) but it doesn't expand far enough to fit my iPad Pro 11. Has anyone sourced a tablet mount for the Cendence RC that can fit an iPad Pro 11? I can always downsize to a smaller iPad, but I'd prefer to find a larger tablet mount...
