Just like the Gemfan Hurricane 4023-3 props the new SL 5125 features Gemfan's innovative hub design that's compatible with both conventional 5mm and T-Mount 1.5mm. This prop is one of the Best and probably the ONLY (At the time of release) 5" Ultralite prop that's compatible with T-Mount shaft motors.
Blade Diameter: 129.54
Hub Thickness: 5.5mm
Shaft Hole: 5mm and 1.5mm T-mount with the optional included insert
Full disclosure: Gemfan is one of our team sponsors, but I found and bought these on my own and this is entirely my own opinion. I got them for a 5" ultralight build with 2004 motors. I actually had some concerns that even though the build was lighter, a thin prop with a shallow pitch wasn't going to give me the speed of my usual 5146.5s. But I was dead wrong about that. These props bring a surprising amount of power and durability. Especially for a T-mount. Nonetheless they are paper thin and super light. As a result even my 2004 motors spool up almost instantly. Giving the drone both top speed, but also an incredible quickness. My FPV image gets blurry when I punch them hard. After a few hard flights the blades take a permanent curve from their own vortex. So you know they're working. Definitely the best prop in its class for ultralight builds. I've stocked them for the rest of the season. Buy them with confidence.
I installed this GPS and now I can't get my drone to fly. The whole set up process messed up all my settings in BF. AS soon as I turn on the drone, the OSD says I have 14 sats. I can't get all the OSD functions to work in my goggles, even though I rooted with WTFOS. This is my first time installing a GPS in a drone and the thing came with absolutely no instructions. There are lots of YT vids showing how to set it up, but none show how to trouble shoot. Spent three days trying to get this to work, now I have a fancy paper weight.
