I have a v2.7 OpenROV for sale, with extras. I purchased the kit last summer (2015), but due to health issues I never started on the build. I have all the recommended adhesives and other extras including an IMU and the LiPO batteries and several chargers.
I have the unit listed on eBay right now, but thought I would list it here as well. Please PM or email with questions if interested, and we can arrange to talk about it.
Thanks for looking.
