Thought I'd share my bad experience with the carbon quality of the Crazepony X210 frame (https://amzn.com/B01IONSHW2 also sold on Banggood). I decided to try it because of price and good prior experience with the H210 (QAV210 clone) which is pretty much identical to the original and very crash resistant.

Building the X210 was not hard, not a lot of spare room but everything fits nicely. I received the 3mm version like many others, despite ordering 4mm, but decided for the price, it was not worth the hassle to return and, on the bright side, was lighter. The arms did feel a bit bendy right from the beginning.

The first few flights were amazing - probably the best flying experience I've had. Unfortunately a few flights, and relatively mild crashes later, I started to notice increasing oscillations. At first I blamed KISS, which is a separate rant , but also noticed the arms were feeling even more bendy.

I unwrapped the ESCs to inspect and discovered a pretty severe de-lamination on the arms. Both front and back arms were affected. Seems the frame does not hold well to crashes at all.



I really like the flight characteristics, so I am considering a real QAV-X 4mm at this point. Wanted to ask you guys what your experience is. Does it suffer from similar issues? Do you recommend another similarly sized frame? 

I am also considering the Xhover MXP200B, the Hyperlite 4mm, MRM Reaper or Switchblade. Something that is small X frame, but though on crashes and with good camera protection.

Wow, that's crazy how much you can bend it due to the delamination.

I have a QAV-X 4mm and I definitely recommend it. It's expensive but also super though, the carbon seems to be top quality.
So far I had only one really bad crash, it dropped from 8-10m (25-30 feet), about the height of a medium tree, with one arm directly hitting the asphalt road. I thought that was it but it had only a bit of delamination on the tip of the arm which I easily got rid of with a file to avoid further delamination.

Here's how it looks after fixing


Besides, it's a great looking frame

This is what puts me off buying a unibody style frame.

I got the realacc 210X 3mm from banggood and so far no problems with the quality. But I haven't crashed it hard yet, so time will tell

Generally true, tho in this case I would be swapping all 4 arms - not much benefit

I used to be that way as well Hamster, I was always thinking that I have more chance snapping an arm off on a unibody frame than I would on a replaceable arm quad.

Truth is I fly both types of frames, and in 2 years of flying and loads of crashing I have snapped 2 arms off quads and both were on NON Unibody frames.

The Tweaker 4 inc and 5 inch unibody frames have been superb, as has the QAV 210 and 180.  I know many people have snapped unibody arms off, but I think that overall the hit kill ratio of frames breaking be it one style or another probably works out the same.


All depends on where you fly and what you hit and how you hit it.  Urban jungle flyers clearly have more potential of causing major damage to airframes, where as open grass/wooded areas is less.

What I really like about the unibody frames is that they are normally more lightweight than the frames with separate arms. And I must say as you Jordan, the X210 flies really, really good. It flies so good that I was actually surprised that I was flying an undermounted battery quad with such a low COG, since I already stated in another thread how much better I think a quad with perfect COG flies (http://intofpv.com/t-lipo-above-or-below...+placement). I think it could have something to do with the light weight (280g AUW for the X210 and around 360g AUW for the Martian 3 frame I was testing earlier).

Here is a GEPRC version of the frame. I don't know about the quality, but from what I have read, the GEPRC carbon quality should be quite good. http://www.banggood.com/GEPRC-GEP-TX-Chi...ent=robert

Jordan that has to be one of the worse carbon fiber quality i have seen
Some put glue on the edges to prevent delamination maybe that would have helped but good CF shouldn't do that...

I am not sure CA would have done much for that......might have delayed it a bit, but it looks like that goes all the way through the arm. Thanks for posting this Jordan, my next build is going to be a 210 and I was looking at that frame.......not any more.....

Yeah, I coated the sides of the carbon with CA and with a black oil-based barker before the build. The layers delaminated entirely, and on multiple arms. I've never seen this on another frame before.

I posted a 1-star review on Amazon and retailer contacted me shortly after, offering another frame. I am skeptical, and the build will be on the shelf for a while I wait and replace, but at-least I requested the 4mm version, which is what I should have received to begin with. Hoping the way the frame is designed, the bottom plate would be easy to swap.

Hahahaha. Wow this story is almost exactly my experience with this frame. I got mine cause the H210s have served me well. When it should up the bag it was packaged in was labeled 3mm and it was so bendy, so I immediately left a review and set up a return. Crazepony contacted me offering a refund plus 10%. I asked if they actually had 4mm and that I'd rather have that. It's been well over a month of emails back and forth. Well it's supposed to be 4mm that should show up early this week, so we'll see. At least they're letting me keep the 3mm too.

I've been down the clone route and after breaking a few decided on the qav 210 and since, the qav-x. I like the fact that all spares are available locally and I haven't got to buy a complete frame, waiting weeks for it to arrive

The Crazepony H210 is an exact copy of the QAV210. They usually show up next day or two through Amazon. Only once has the frame come with a 2mm top plate so I always replace it right off the bat with an authentic one from the local shop. Up until this X frame I've had great experience with them. In fact my first was a true QAV210 but it broke just as easy as the clones that proceeded it for four times the price. By easy I mean hundred foot powerloops straight into the ground. I will add in the X210's defense though is my old QAV250 has about the same amount of flex to it's bottom plate. Most of the time I'm of the strong opinion that the cheaper route in this hobby is going to cost you a lot more, but frames breaks no matter who's making them.

Trollhammered, our experiences seem identical - that is hilarious

I will give it another week and if the replacement frame does not arrive or it is not 4mm, I will not bother with it. I have a few other frames sitting around, including an H210 - which has been fantastic. Most likely I will order an authentic 4mm QAVX tho, I really liked how it flew.

Banggood just released a new version of this frame. Looks like the changes are a better camera holder, better carbon and led lights.
