Looking at making a 1:2 scale r2d2(not in crazy detail) from wood and just for reference I was wondering if anyone had seen a pretty small motor with high speed and if possible, a mount?
The wheels I'm looking into are 3" diameter by 0.2" wide but I could change quick. Needs to be under 4" as the feet cover is only 7" at the bottom and 3" at the top. A servo style motor would fit best but don't see any 90rpm high torque servos. Any suggestions?

Oh wait. Youre looking at 1/2 scale R2D2 and want to run on AAs?
Cheaper AA batteries have average capacities of around 1000mAh in my experience. 1000mAh/2A = 0.5 hours...
Consider something with a larger capacity, as recommended above. 7.2v 5000mAh LiPo would last 2.5 hours, almost twice as long as the best AA batteries.
