Just another quick update. Took R2 for a walk and he really drove nice. I got the controls fixed so they are no longer reversed. Took a little bit getting used to controlling the drive train as well as sounds and the dome. He took the sidewalk bumps pretty good considering .... What a blast.
I just ordered 2 new batteries for the DX6 transmitter because the one in it doesn't last long at all. I think it's old or is just a bad battery.
I'll get some video of him driving this weekend.
