Which of the following Hacker motors would be the preferred choice for a Diablotin Super if I was interested in max power vs. max endurance?

Is there anything else that can compete with the Super? It's all I seem to hear about lately.

What does 13S mean?

What other brands would be equivalent or better?

Any tips on aerobatic setups with the rest of the electric related equipment?


B50 18L $179.00
B50 13S 6.7:1 $249.00
B50 11S 6.7:1 $249.00
B50 9S 6.7:1 $249.00
B50 10L 6.7:1 $269.00
B50 10L 5.2:1 $269.00
B50 11XL 3.7:1 $289.00

TIA,
