Review on ReadyToSky 220mm FPV Racing Drone Frame Kit - Martian II Carbon Fiber Quadcopter Frame with 4mm Arms, 5030 Propellers, and Lipo Battery Strap by Robert Sorrells

I love this frame. I've ridden this thing at speed on frozen ground and metal posts, rock faces and it's been fine every time. I've bought frames that haven't survived a single fall, but this one is very strong. To be honest I see no reason to spend $100 on a real Alien frame. Except for the great purple screws. I ended up not using the red PDB that came with the kit just because it doesn't have a 5V pad. I used my typical Matek PDB which I use for all my frames. I was nervous that the lack of PDB would affect stiffness, but it didn't really happen. I still use the black "pad" that goes under the PDB. I highly recommend this frame.
