Chopper recently attended his second convention of the year. I've applied some of the weathering to his paint and started on the dome electronics. Unfortunately I blew up the LED lightstrip because I was in a hurry. A quick and dirty replacement was a red reflector from my classic Mustang's taillight. It didn't light up but it didn't look horrible.

At some point during the convention an odd R2/Chopper hybrid was created.

This convention had a lot of open floor space so I was able to keep Chopper mobile nearly the entire convention. He ran about 5 hours straight and still had just enough power to get him to the car for the drive home. Mark's R2 was running a single 12v LiPo and got about 4 hours of runtime.
