Ofna hyper mini st-e

[leonard]

Hi, I'm looking into a ofna hyper mini st-e. I read an article that they used a mamba max with a 4600kv motor and 11.1 lipo. I have a mamba max with a 7700kv motor and was wondering about running 7.4 lipo cause i already have this stuff. According to the math it would put out a little more rpm but I'm not sure what any other differences there would be. Any ideas on this? Any help would be appreciated!! Thanks.
