i currently have a sxx v2 with mod+stock upgrade, any hints on settings for this speed control? im currently sitting at 1/6/2/2 with orion vst mod. also only running '1' because i see all setup sheets running 1 (3.2v lipo), but default is 3 (6.4v lipo), why are setups running "1" or does this refer to something i am missing?
