Ok, I don't know if my hobby shop owner misguided me or I made a mistake and picked up to wrong prop size.... I purchased two 10x7 propeller, I'm reading everywhere that I should get a 11x6 or 11x7 with that size engine.

What are the implications if I use a 10x7? Less torque, higher rpm? Can I still use those prop, or should I really buy a 11x7?

Regards,
