 R2-D2 Return Of The Jedi "A Plastic Model Conversion"

Bought this model from Sparts1954 over on Ye Olde Rocketry Forum ... his brother had started to build it, so I figured it would be a great candidate for a PMC (Plastic Model Conversion) to a flying rocket.

The kit is actually a 1983 Re-Boxing of the kit released in 1977 from the original Star Wars movie. Basically a new box and re-printed instructions. Nonetheless... it's made in the USA... which is awesome.

The kits all there... I did an inventory of all the parts. In fact, it had an extra part from another kit... it is marked "Made in W. Germany". Thanks again Chris.

It's about a 6" tall R2-D2. I figure an Estes D-12 will be a great motor for this PMC, with a rear eject spool.

Here's what all the pieces parts look like:
 

 Here's the box art... pretty cool... I'm a sucker for Star Wars stuff:
 



 
Here's the MPC assembly instructions:
 






And finally... a photo of that extra part (with an Estes C6-5) for scale... kind of looks like an ejection seat for a fighter plane?

 Body Mod's Day 02

Cut the 1-1/4" dia. hole in the upper body for the BT-55, then sanded the bore with a Dremel to fit the 1.325 O.D. BT-55.​​Cut the BT-55, the Bulkhead and the 1/4" Dia Dowel.​​Did a mock up for BT-55 height inside the Upper Dome.​
 







Injected glue into the cavity between the O.D. of the C-80 and the I.D. of the body. Also started gluing the Bulkhead and Dowel into the C-55.​

 Laser X2.. a two stage sounding rocket

An upscale of the classic Centuri Laser X design, but staying true to the reality of a two stage rocket.

This one will use a composite motor, with a delay, for the booster.  The ejection charge lights a fuse that's connected to the sustainer motor. 

Should make for an interesting flight.
