[Robotgroup] Drive a Droid proposal...

Wed Jul 9 12:59:55 PDT 2008

Even better, I have this set in storage I built years ago for the Star 
Wars episode III premier:
http://www.cozmicfunk.com/SciFiSet.html

You could use that for your backdrop (minus the Boba Fett), it could be 
arranged in a semi circle because it has four panels. I was using this 
for First Night proposal years ago and it never flew, The group would 
have to be responsible for moving it etc.

I would be happy to loan it to the group since you guys have been 
generous to me :)

I think this would be more fun and intuitive than a standard 2 stick transmitter. The stick would be proportional if per-chance someone wanted to do a non full-throttle movement.
