Seems like a moot point given this little bit of news: http://www.tfw2005.com/boards/transformers-news-rumors/401936-third-party-accessory-leader-class-starscream.html But I was in the middle of kitbashing some jet engine thrusters for my Takara MP-M01 (Movie Masterpiece) Starscream. I was inspired by Frenzy_Rumble's previous work on a more screen-accurate Screamer, using two of Energon Scorponok's jet engine feet that I got cheap off eBay. I have zero experience with kitbashing and/or painting of any kind since I was a kid, so this is all a little new to me and my first real attempt at customizing anything TF-related. Still, it was a fun learning experience! I MacGyver'd the boosters onto Screamer's back using parts taken from two wire/shirt clips that came with JVC Air ear buds/headphones. Shame I had to scavenge them for parts since the clips themselves are very handy when used for their intended purpose. XD Anyway, the thrusters slide and clip on to Screamer's back fairly securely with metal pins I pulled off a miniature Yankees Stadium souvenir replica (they were the foul ball posts, haha - and they fit nicely into the holes meant for the spring hinges after I removed them from the clips). After unscrewing and taking the thrusters apart, I just slotted the clips into the holes on the jet engines meant for Scorponok's shovel-feet, screwed them back together, and whaddya know, everything is a perfect fit! The boosters are easily removable (sliding into the empty space between each top fin and its hinge) and don't hinder the placement of the pegged-in missiles. Although not adjustable for poseability, they can stay on the figure snugly even if I turn Screamer upside down. I had planned on painting them a gunship gray to match the rest of Screamer's color scheme but with these new 3rd party add-ons, not sure if there's a point now. XD Oh well, again, was fun experimenting and I do like the results, even if they sit on Screamer's back a little too high and a bit too far off to the sides. I still think they look rather good on him as is but we'll see if the 3rd party add-ons will come out any better. Enjoy!
