These motors are great for 2S like Beta75X! They are lighter than most 1103 motors on the market because the bell design is very open. In fact, they are no heavier than my 1102 engines! When using these motors with BetaFPV 2S ESCs, they are wired without soldering. I am completely satisfied with the soldering, but I still really like this convenience! I suggest using the 40mm props that BetaFPV sells. They work great with these engines. You push the shaft and hold on. I do not recommend using these motors with larger propellers (e.g. 2" or 3"). Those big bolts can slip on the shaft but 40mm bolts work great!
