Finally got around to painting one of the two Earthrise Starscreams I had stashed into Sunstorm. I was dreading trying to keep the wing stripes but turned out easier than I thought.
Paint rub is an issue and the tolerances seem really tight, so I doubt I'll be transforming it much.
And with the recent reveal of Nacelle, I'm expecting an announcement of an official Sunstorm.
But at least the symbols are right way up in robot mode!
