Nothing earthshattering for the community, I'm sure, but I finally got the guts to try the MP Starscream leg mod. I figured it was either this or pay $100 for the iGear one and then have to find Reprolabels. I was so proud I had to share! Right shin rotated for the photo (damn!), but overall it was just cut the fins, open them to create a slot for a sliding screw. Screw the bottom part of the fins to the leg and glue the top part to the wing. I'm emboldened enough to make a weekend of MP Skywarp and Ghost Starscream now.
