Gemfan Flash 7042 Durable 2 Blade Choose Color

Works perfect

Just brought this prop works great for my application. Has good thrust with my 1960 KV motors.

These are the first props that really worked well for my 7" Floss racing setup - on 6S 1500KV the speed on offer for a setup with GoPro session on top is still seriously phenomenal, and more importantly the grip and smoothness are excellent. Balance and smoothness are impressive, and the low weight makes it easier to tune around these. If you're trying to run a 2306 7" lightweight setup, these would be my primary prop recommendation just because the low weight makes tuning around smaller stators excellent, although on y primary 2507/2408/2508 rigs these are still excellent.
I'm partial to the clear versions, since they flatten out at a higher speed (the opaque versions seem to flatten out quite a bit around 115mph in level flight, the clear ones pick up almost another 10mph).
Durability is also shockingly good for a large propeller - I actually have two chewed up set of these that have lasted well over a year and dozens of packs all of which involved crashes and scraggle punches, but they still fly well enough to run race gates or cruise at speed.
The only comparable prop I've experienced is the latest HQ 7x4.5x2 grey biblade, and it's more of a feel difference than actual performance delta between the two, these carry forward the same tendencies of the rest of the Gemfan Flash line of being a bit softer in the lower-mid throttle range, but resulting in an overall much more linear throttle response across the band with appropriate motors.
