My RP5 driven by a 7.4 Li-Po battery and a 25A controller (overkill) gets a speed of 12"/sec on carpet. The ‘features’, as well as Carim’s spreadsheet, quote 6"/sec.
Since I received it last week, perhaps it’s a new version. I just want to make sure that I’m not burning up the motors. The RP5 works great and I’ve made many runs.
