This R/C R2-D2 Action Figure is like a Star Wars fanboy’s wet dream come true. The size of a regular action figure, this tiny droid is fully controllable from the included lightsaber remote. Authentic R2-D2 sounds, turning head and red LED eye complete the package. No more playing with your old skool Star Wars figures by shaking them and talking in a funny voice, this is the real deal… and we don’t kid when it come to Star Wars. We would have killed for this little R2 gem as a kid and it’s still pretty damn cool as an adult.
These mini R/C R2-D2s come directly from Japan and are fully licensed by Lucasfilm. Ignore the Japanese instructions and simply flip the switches on the back of the R2 and the remote to get things going. Button style batteries are included. Our supply is limited so get these while you can.
By the way, this is selling for $29.99.
