Oh no no no, Castle Link Live allows for on-the-fly settings changes!!
I am sold on this now! $800 or so for the car and another 100 bucks for an older i touch or iphone. I do think I will pick up some 5k 40c lipos, but that is less than 100 bucks too. Almost every big rc I have done has cost around a grand if you factor in the batts and radio gear.
