Thought people might be interested in this as a great upgrade to the E7SE.
After having heaps of trouble sourcing Ralphs trays for my E7SE and not keen on paying $50USD just for postage to get the 3D printed ones sent to Australia I decided to go all in and try one of Patricks Goblin 700 tray systems.
I'm stoked with how it has turned out and absolutely love the ease of sliding the batteries in and out. I can land from one flight and be spooling up again for the next within about 20 seconds.
Sorry about the average photos...
