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.

The iFlight XL5 V3 is a fantastic freestyle frame for the price. It features chamfered edges on some very nice quality carbon fiber. My goal for this build was to use high quality components at a relatively low price. Not only that, but I managed to reduce the number of solder points to the bare minimum. I've never built such a plug-in-play quad! The flight controller has an integrated VTX and doesn't..

Update! Happymodel has released a new V2 Frame which uses a more durable plastic. The Happymodel Mobula7 is one of those rare treats to hit the micro scene. Countless models hit the market every month, but this one just happens to check all the boxes. It's a 2S brushless micro with a 75mm motor stance. It's slightly larger than the more traditional 65mm brushed micros, but it's still quite small...

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 used straight standoffs at the front (you can see in the more recent photos), rather than the dumbbell shape ones it came with, because the 3D printed micro FPV camera mounts I use only fit over straight ones. I haven't had any issues with any of the props I've used. 1mm clearance is plenty & completely normal on minquad frames. If/when the prop flexes, it can only get further away from the standoffs/frame - you're flexing, not stretching!
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've built & flown many different frames with similar clearances & it's literally not once been an issue for me. Like I said, if a prop does bend upwards the tip will in fact curve further away from the standoff & the top plate.
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.
