The next logical step after my recent 6" build is to do a 7" build, right?
Going for something a bit more modern this time; F4 flight controller w/ OSD, BLHeli_32 ESCs, etc. on a less oldschool looking frame. Using the same 1900kV F80 on 4S as my 6". I'm not a fan of bottom mounted batteries, but the body simply isn't long enough for a GoPro & a big 2200mAh 4S both on the top plate.

I just finished my XL7 fitted the props and they hit the front standoffs! I have replaced the standoffs with thinner ones that do not have the larger diameter at the top and bottom that are supplied with the kit but even now the clearance is less than 1mm. Any flex in a prop and its going to hit the top plate with potentailly disasterous consequences.
Did you have the same issue?
I have replaced with straight standoffs but still not happy about the minute clearance, also if I hit some scraggle and a prop flexes upwards its going to hit the top plate.
I noticed that the XL7 now comes with 294mm not 284mm motor to motor so I have asked for my arms to be replaced with the new variant which no doubt has been modified due to this issue.
I'm having the same problem. I first bought "Gemfan 7042 Flash Propeller 7x4.2" and while they don't touch the standoffs, the clearance is less than a millimetre. As soon as I take off, I can hear them touching the top plate because that's a few millimetres wider and the props are flexing up. Once I move them by hand I see where they touch. I was hoping that other props would work and these did: "HQ Durable Prop 7035 7X3.5X3V1S". They are just that 0.3 mm shorter. Still the situation is a bit anoying. BlueFish, if you found a solution or want to exchange ideas, let me know.
So tidy and thorough!
