Yes, but I found on another part of their website, the ability to place an order for it. Based on the above post from MGS it is procurable now. I need to ask my IA if we can install it now, or wait for an STC just for the plastic adapter.
I sent my picture to Uavionics and they said they did not have an adapter for the wingtip. I'm going to check with a 3-D printer int he area. I made this wax model that I need scanned and printed.
