Hi, one guy here (thanks Tas) got his trial TSDZ16 and made little overview, I post photos here if anyone interested, as still little info about it is available:
You will burn xf19r soon with that amount of power. Mac is weaker motor than xf19r, has issues with some controllers too. Where did you find steel gears and maybe clutch replacement?
Pajda, you have probably some mistake in M58 test capacity by 1C discharge in your table, I always get results of 5500+mAh with 8A. And 50G 1C test is underrated too, maybe some cell clamp problem?
