Good news, I got my replacement back. Bad news the threaded part you bolt the saucer onto had something in it. It was soft, maybe something to protect the threads during painting? Who knows. I was able to chip it out and run a bottoming tap in it and now all is fine..... With that one.
My other one with the gap in the seam on the secondary hull I decided to keep it until I noticed two of the orange leds on one of the nacelles stopped working. It should have 5. The right one, left as your looking at it in the attached video, now only has 3. I tried a new set of batteries but no go.
I've requested another return label. At least I have a decent box to send this one back in since they sent me new foam with the last replacement.
