I am just about to buy a Rapida Pro and wanted to see one mounted up first. preferably in a touring car (a JRXS if possible

).
Does anyone have any concerns or issues with this esc? I have only heard good things about it. Just wanted to make sure before I buy.
How "smooth" is the Rapida Pro compared to other esc's (eg. VFS-1 pro comp, GTX, Q2 and GM)?
And finally, is the mod touring profile on the back of the instruction manual a "good" point to start? and what would be the first things to change to suit track and environmenatl conditions?
Any help or advice would be greatly appreciated.
