No, 1 x 5200 6S Multistar . Next test 2 x 2200 6S Zippys. After that 2x 5200 3S Traxxas in series.
I predict the 2200's will still be top dog but post those results! I could be wrong.
Where are you mounting the single and doubles? That can make a difference.
My next test since I'm Thunder Power poor at the moment will be with 2 nano 2650's. That holds promise I think to get beyond my 27:36 mark with the 2200's.
