Readytosky S500 Quadcopter Frame Stretch X FPV Drone Frame Kit PCB Version with Carbon Fiber Landing Gear

Great frame, and easy assembly. I honestly was expecting to have to re-drill or slot the frame coming from China. To my surprise every part fit exactly within a mm and there were no issues with stripping the small screws out due to misalignment. My only real issue was I paid for a pre-soldered board and got the regular non soldered one. For a few bucks difference Ill let it fly though. One note, if your good at building from examples this will be a breeze to assemble. If your expecting detailed instructions there not contained with the kit just a single piece if paper with exploded diagrams. Most would not have a problem especially with YouTube and such. But wanted to share since this is my first review. Overall great value for the money. Would have cost me more in time and effort to 3d print and get the parts myself individually.

I replaced my DJI Phantom 3 frame with the Readytosky S500 Quadcopter Frame Stretch X , It is lighter and flies so much better and longer with out all that extra plastic weight . It takes some engineering skills, but worth it. I had to modify some of there parts, but all and all it looks better, and not like a toy. I also have there S550 hexacopter frame, but I built it from scratch . again good sturdy light frame. Flies great with Pixhawk auto pilot.

I'm just getting into DIY drones, so my review wont have a lot of the technical jargon you might be looking for. So far my experience has been totally fine. However, SCREWS FOR THIS FRAME ARE HEXAGONAL, AND COME IN LIKE 3 DIFFERENT SIZES. Just a heads up. Also, THE INSTRUCTIONS ARE PRETTY LAME The guys at Readytosky probably need a better Chinese-English translator, just sayin'. But if you know what you're doing, it's pretty easy to build. I'm happy with this purchase.

Great frame, but use thread locker. The included screws do NOT have thread locker on them. I used Thread Lock Blue. I’ve flown this 3 times and crashed it once with zero damage ( my fault, I didn’t have the UAV balanced ) to the frame. The legs are the weakest link so I used a cut off wheel and took 1 inch off them. I purchased a second frame and extended the battery holder to allow me to use a DJI 2200mah battery

***Update*** 5-1-21 So after flying it for a few days, upon landing normally the legs broke again. The "T" part that holds the bottom horizontal rod to the thicker vertical rod snapped. Eventually both sides did. I used a couple of zip ties to hold it all together for a few more flights, but then I crashed it from about three or four feet in the air... It was a coasting crash - not too fast at all... And then the bottom PCB board snapped. After that, it was basically impossible to fly because of all the vibrations going to the gyro on the flight controller. The arms are still in pretty good shape, though they do flex a bit when applying throttle and the props start to lift the quad. I was using a 4S set up with a 6000mah battery. Fairly heavy, but when it was first built it flew pretty stable. At least until it started breaking apart. The PCB board definitely needs to be a lot thicker since that's where a lot of the stress it going into. The legs need to be redesigned and any parts that hold them together need to be stronger as well. It's a nice design and all, but very weak when it comes to landing hard or trying to FPV it. A lot of wobble in the camera as well - even when nothing was broken. Guess I'll be going on to the iFlight XL10 that is pretty much solid carbon fiber. The idea of this frame is nice, but unless you have a 3D printer to make your own legs it's not worth it. The arms are fairly strong, but one little crash from just a few feet in the air and they're gone. Granted it is fairly cheap for all that it is, you might want to consider something with a bit more carbon fiber...
