Props for 450 quad

[BenMadrigal]

I have 10in props for a 450mm quad but was wondering if I could fit maybe an 11in. I think I can but would like some outside opinions.

Is the motor layout a perfect square? If so, then the biggest prop you can fit is a 12 inch prop. Before you move to bigger props, make sure that your power system is able to handle the extra load of swinging a bigger prop. You might also have to retune the PIDs on the flight controller.
