Propeller size and clearance

Hardware Multirotors

Good day all
So far I have been using 2312 motors with 9450 props on my quads and my hexas. Its actually the DJI 2312S and 9450S which I want to move away from , as it seems they will be discontinued soon. So I am on the hunt for new motors and props. Currently testing the LDPower 2213 920kV motor. I have two props to test with this motor : 9450 carbon fiber self-tighning and the 1050 carbon fiber. I have mounted the 1050 on the quad and busy with some testing.

My question:
I would also like to test the 2213 with the 1050 prop on my hexa. However, the hexa motors are closer to each other than the quad. what would be a safe clearance between prop-tips?
On the hexa I have 27.3 cm motor center to motor center ( 11.14 inch ) which gives me just over 2.5 cm clearance between prop-tips. Are there any guidelines for this ?

Some detail:
quad frame : 450
hexa frame : 550
FC on both : pixhack V3
ESCs on both BLHeli32 30 A
Battery : 4S

many thanks !!

2.5cm clearance between tips should be plenty, unless your frame is extremely flexible. On the large X8s that I fly, the props have around the same clearance, but the props are 30" tmotor units. You should be fine with the smaller props you are flying.
