YoungRC F450 Drone Frame Kit 4-Axis Airframe 450mm Quadcopter Frame Kit with Landing Skid Gear

Sturdier than I expected. The arms do use a good quality of plastic. I did not use the legs, I may. The legs are as others say very flimsy but this is good, they bend and absorb impact and are cheap to replace. I use the stubby legs that are build on the ends of the armsThe weight with no legs was 312gWhen I hold this frame by two of its arms and try to bend with just enough force that I see a small deflection I notice the bending is all in the arms. The fiberboard looks like it will not be very strong but it is. Even with all the cutout holes.This is an old workhorse drone frame, not intended to be a racer.

Easy to put together. Good quality. So far has survived a few hard crashes of the drone outdoors.

Used as a donation for a few parts I needed. The two red arms mostly. The white arms are not as strong broke both of them but I am having problems getting an arducopter flight control working. Other parts swam to be holding up.

I've bought two of these and if you're a beginner, you'll probably want to buy two also. I built my first GPS drone with this frame and it's a pretty sturdy frame for a first time drone build. The landing gear are crap and will break very easily so I just don't even bother to put them on. I'll probably be buying another one for another GPS drone build with DJI Naza system.Update 09/01/2019I have since bought a total of 3 of these kits lol I have 2 fully built and flaying GPS drones with this frame. I will list my specs for both so hopefully someone might find it useful.Drone #1 (with camera attached)Flight Controller: Airbot OmniBus F4 ProReceiver: FrSky XM+ESC: Turnigy MultiSar 30A BLHeli_S 4 in 1 ESCMotors: 2 RacerStar 2212 920kv & 2 Turnigy Multistar 2212 920kvGemFan 8045 PropsBeitian BN-880 GPS moduleRunning: iNav Flight2nd Drone:Flight controller: Mateksys F405-STDESC: Racerstar REV35 35A BLheli_S 3-6S 4 In 1 ESCMotors: Racerstar Racing Edition 2212 BR2212 980KVReceiver: FrSky XM+GemFan 8045 PropsBeitian BN-880 GPS moduleHiLetgo HC-06 RS232 4 Pin Wireless Bluetooth Serial RF Transceiver ModuleRunning ArduPilot Firmware and QgroundControl for Android

Very solid Quadcopter Kit. I used this for a drone class in college which we built our own drones all using this exact brand. It survived a crash and held up great!

Ordered and received Fast from Amazon. Fair quality, little heavy weight and arms have lots of molding flashing that needs to be trimmed with hobby knife and/or sanded. Also no assembly instructions included but came with screws for frame and motors w Allen wrenches. No lock washers included which would be needed or use Blue Medium Locktite.Another thing is mounting points for arms not prescion drilled/molded which causes arms to not line up correctly with opposite arm. Had to file mounting area on arms and slightly re-drill holes for exact fit and alignment.Bottom PCB plate includes built-in power distribution traces, not sure if I will use because of the electrical interference with Flight Controllers and GPS many folks mention on forums. Will update review when get build flying, having to reorder motors since received bad ones ordered thru Amazon.Overall not too bad for low priced F450 clone kit.

I bought this frame to build a drone from scratch. On of my ESC's burned out and the drone fell from a height of about 30-40 feet. Only one arm of the drone frame snapped! Saved my parts and everything else on the frame! Well worth your money.

The frame arms and the boards are of good quality and durability. I thought the landing skids would be a nice touch to my build. The drone found the weak spot in the skid on the first rough landing. They are nice in concept but not designed very well and poorly implemented. But you will be happy with the other parts. Like others have said, get another for spare parts.
