Tryng to rich 100 mph

hello gentlemen, I decided to bring a modification to the little Mistyc, namely the drivers, a rear support for a much stronger setting and this time I will actually run with 8 cells, the support is made by hand with a drill, some files and abrasive paper, once with more rigidity will also come a bit of resistance.
I installed 2x ZTW 200A and 2x TP 4050 in the small boat and there is still room for two 4s batteries + an external BEC with a 2s
