Gemfan 513D 5149 Tri-Blade 5" Prop for 3D Flying 4 Pack - Choose Your Color

work great but are bigger then 5"

i am happy with the result. they cope with crashes well, sound ok in both directions. they are less efficient then normal props which is to be expected. They wont mount on all quads as they are 5.1" sized

3D mode

Add another dimension when flying. It’s so hard but so fun! I wish more ppl flew 3D mode.

Great Products, Fast Shipping

Haven't used them yet. For upcoming 3d project.
