Usmile® S500 PCB Quadcopter Frame Kit with Landing Gear Skid for fpv quadcopter fpv drone able to mount Gopro Gimbal F450 Upgrade Similar to F550

I finished the build for this frame a few weeks ago and have been on approx eight flights so far...Very pleased with the performance, stable and solid all the way around. I'm using Afro ESCs, 3DR motors and APM controller. Easy to assembly - it even comes with directions. The bottom mount rail makes it easy to balance a camera and battery for perfect flight. The only compliant is the integrated PDB... on mine a couple of the solder points came off completely. I'm pretty sure I just got a bad one even so, the seller was quick to send a replacement - shipped in one day. Five stars for service, four on the product just because of the issue with the PDB.

This product is such a quality, my drones fly effortlessly and high. Its so huge! It is the same as it was described by the seller. I really like it, very lightweight as well and sturdy. I am happy that I did not regret having this. Plus the color is perfect, every detail is awesome! Highly recommended.

cheaply made

I have purchased 3 of these frames. Please note, 4 star is because of fitting issues. It does work! But with the knowledge the holes are "slightly" misaligned. Will it effect your build "no" but you will experience slight frustrations, yes. However it does work perfectly, it is a great at low price frame just expect some difficulties during building. The frame does perfectly as well as any other S500 frame. While on my 3rd frame, I would buy again and again!

The frame is very sturdy and well built (Except the legs which easily snap). It includes a detailed installation guide and extra screws for additional aftermarket attachments to the bottom plate. However, mine had a short in the back left ESC connection which burnt out two of my ESCs. It is likely just my unit but it is worth mentioning. Also, the kit doesn't include an alan key for the screws and bolts, so you need to supply your own.

Sturdy frame, easy to assemble. Has a lot of slots for adding devices such as controllers and GPS.

I hate to give this 3 stars but it just didn't deserve more. I like everything about this kit: the color scheme was perfect, it is very sturdy, and the PDB/ main level/plate was solid. However, the top level/plate didn't line up correctly and I had to bore out the screw holes and take in the edges. It very well could be that I had the only faulty kit. But it was a pain. That being said, I would buy another one and take my chances because the good far out weigh the bad.

This frame worked great, not very stable with APM controller but works amazing with NAZA. FAAAAAAAASSST drone. I want to race a Phantom 4 in "Sport" mode and I'm only using 3s lipo and cheap emax 2213 motors.
