Hobbypower X525 Quadcopter Glass Fiber Folding Kit ARF With Mini KK2.15 Flight Control Board + 1000KV Motor +30A ESC

What do You expect for this price? All the parts work but they are the cheapest quality. I had problems with my kit from the moment I opened the box.First the distructions, that I seldom read, are very poor and are difficult to follow. They look like they have bee photocopied many times. Maybe a 3rd or 4th generation copy.Second one of the ESC's, speed controllers, would not work properly. The ESC would not throttle calibrate like the other three did. So I sent a request for a new one and have not heard from anyone concerning my issue. Thats okay, I ordered another ESC of the same make and four more of a different brand. I really love the new ESC's I got, Spider Opto 30a with SimonK from Amazon. Killer ESC's!The frame is very delicate. Be careful not to break anything assembling the frame. I know when this thing crashes its going to require a lot of surgery.The 10' x 4.5 props are garbage. They are not balanced and they bend and flex so much! My 3rd flight one broke in mid air and when it hit the ground 2 more broke.Once I got this thing flying its pretty good. Not the easiest to control. But its a lot of fun. I also purchased a FS 9x controller for about $100. The battery I used is a 3s 6400mah lipo for $65.00 also from Amazon. Theres a program called "Ecalc" that lets You put in all the parts to see if Your multirotor will fly before You buy anything. This kit can use a huge battery if You wanted to, but I would get better props before You over load it with too much weight.To be fair You get what You pay for. You can't complain when Your in the air for less then $300. A quality quadcoptor will cost five times the price of this $130 kit. I would still recommend this to anyone getting started, just buy more spare parts. The build IS fun. You can always upgrade as it breaks...

If you plan to build this quad, you need to buy a few extra things!Extra male to male servo lead wires.Depending on the battery you will need to buy/Salder xt60 instead of the supplied t plug which none of my batteries have so I read of changing the battery, convert the quad to a xt60.(. I have other quads using the xt60 so it's easier for me.)There are literally and I mean just pictures with broken English for directions. Here is a pretty nice guide to follow. Make sure the longer screws go into the arms of the quad. And the shorter screws go into the landing gear/feet.http://bestquadcopterkits.com/how-to-build-diy-quadcopter-drone/Transmitter/receiverMy fly sky fs-t6 Has also 0 instructions on what 1-6 on the transmitter are so buy one that has any directions that make sense.Battery and battery charger. I got a few around, planning on using my 2200 20c.Plan on going back and redoing a few things since I kept changing things since I had 0 instructions. So do not tighten anything fully since you might have to go back and redo a lot of it.The kit is great but for a beginner its a pain and a learning curve. Make sure you have the basic tools and saldering iron with Salder. A batter strap, zip ties, and a computer laptop nearby to check online forums when you run into problems. Which you will.Good luck and hopefully I hook up my transmitter bind it and start flying as soon as possible.

The parts here add up to a great quad for an insanely low price. This quad will NOT crash very well, but how many do? The main issue with the kit is the lack of clear instructions. For putting together 99% of this, that's no problem. For the other 1%, good luck. Getting the ESCs calibrated was actually surprisingly simple, but figuring it out was very difficult... at least for me.I am sure if you've built one before this wouldn't be so hard. Pretty sure I could another board and esc set easily from all the stuff I learned, and I suppose that's the reason why we build this stuff. It was just hard to get the info.Finally, some parts we got lots of extras. Others no extras. One of my propeller mounts (metal), was not stripped, so it would not screw on the prop. I have yet to even fly this thing, but I bought it for the parts mostly. I don't know if I will even use the KK board in the end, I intend to add one of those Tegra K1 devkits to it. I am bummed to have to wait a few days for that tiny part that debilitates the entire thing.Overall though, for this price... cannot complain much at all. I expected poor instructions since i read the reviews. Whoever did them, I think has a good sense of humor though.

It is an easy build if you can solder and have build brushless models in the past. But the quality of parts can be sketchy at best. Mine arrived missing some washers and screws. I quickly built this in less than 6 hours and was able to test fly it with a KK2.1.5 board. Your props will be horribly out of balance so balance your props first! Mine also came with a motor that was defective and stopped working before I had a chance to really fly it. The motor itself was very very very out of balance and wobbled, but it solved the problem and just stopped working. Ordered a new one and spent a little more money on it.They prop adapters are a joke will visibly have tons of run out, making the vibrations insane no matter how well you balance your props. This vibration will transfer to your FCB and makes it IMPOSSIBLE TO FLY until you remove the vibration. The trick will be to quiet down the vibration before it will fly at all. I have yet to see it fly without tons of vibration but I have my new motor on it's way.All and all it is fun to put together, but be ready to spend more to make it fly like you want it to.
