I run a V3.1, which is bloomin' amazing buddy, but, i also run two Sky RC toro 120A units, the alloy ones, and i find them VERY comparable in set up and performance to the Hobbywing, punchy as hell TBH, apologies for chiming, but may save you some cash buying new too?
Ive been running the SkyRC for a good while now with zero issues
