YoungRC 4inch FPV drone frame kit RC Mini Ran'4 Carbon Fiber Frame Kit

I love this drone frame I got this drone frame, and honestly, this thing is just too cool not to talk about! Putting it together was surprisingly easy, and it's super strong. It looks amazing, and the price is just right. It's a bit big for indoor flying, but you can still manage it. Outdoors, it's a champ – the wind won't push it around too much. I'm really excited to complete the drone with the other parts. If you want a solid frame that won't break the bank, give this one a shot. Happy flying, my friend!

Great Frame! This is a very close clone of the flyfish LR frame / Flywoo LR4. TPU parts are a bit different, but if you want to re-use things most will fit. In my case, I was doing an update on an LR4 v2, and needed enough clearance for a 20x20 board, and walksnail air unit. This took all of it well - although it's a little tight! Build is intuitive, so if you've done a build before you'll have no issue (and if you haven't look up a video for the flyfish atlas or flywoo lr4) The folding arms is a neat feature, but if you loctite the screws (and you should) it isn't going to do that anymore. In the end, this is a great frame for less than $30!

product came shipped in an odd fashion. it was like one of those russian nesting dolls but just a series of bags . the smallest of which appear to have been hand sealed by a lighter. the actual components appear unaffected which is nice BUT there's no parts list or even a build instruction which is a big head ache for a beginner like me especially when you have over 30 parts. some of which are obvious and can be build from the sales image but this is going to be an evening of frustration I can tell. depending on how smopothly this goes I may buy more frames. the price point it right, the product came in decent condition. the lack of instructions is just a huge nuissance for someone with no experience building these things

Very light frame. O4 Pro compatible with Flywoo LR4 prints. Fit was good, but finish left something to be desired. Rough edged, and TPU prints are not well printed. Short frame, so O4 pro mounting with a 20x20 stack is tight.

⭐ Explorer-Style 4-Inch LR Frame Review Broke an arm on my Flywoo Explorer 4" LR and couldn’t find replacement arms anywhere in the U.S. Found this frame that looked nearly identical, ordered it, and had it the next day. Everything swapped over perfectly — no mods needed. Reused all my Flywoo standoffs, camera mount, and TPU parts, and even the VTX standoffs and screws for proper spacing. Didn’t touch a thing in Betaflight — still running Flywoo’s stock PIDs, and it flew like it was on rails right away. Top and bottom plates are slightly thinner than Flywoo’s, but the arms are thicker and stronger. It’s been through two crashes with a heavy 4S 18650 pack and came out with zero damage. Honestly, I think it flies even better than the original Explorer frame — smoother, more stable, and feels locked in. For the price, it’s a no-brainer: Flywoo arms are $10 each (when you can even find them), and this whole frame costs about the same as two sets of arms. If you’re rebuilding a broken Flywoo Explorer HD or starting a new 4-inch long range build, this frame is 100% worth it. 🛠 Reuse these Flywoo parts for a perfect fit: Camera mount (TPU + standoffs) All standoffs VTX standoffs and screws ELRS & VTX antenna mounts Buzzer mount Also includes a nice TPU belly bumper with a carbon insert under the mid standoffs — adds a bit of landing protection. Bottom line: everything fit, flew better, and handled crashes like a champ. Highly recommend.

Good weight for 4". The 3d prints are nice, but the vtx antenna is kind of at the wrong angle to connect to a mounted 20x20mm vtx, using the stock holes for it. Would buy another. Would like to see spare parts, but its cheap.

Junk pieces are small and flimsy. There is no assembly instructions product has no documentation anywhere requesting a refund asap

I’ll start with the only real complaint I have on this frame, I feel that the three carbon plates that compose the body of the frame are a tad thin, especially when you consider the narrow standoffs that are included with the kit. However, the performance of the frame exceeds my expectations. It’s definitely designed with much more aggressive geometry, so I wouldn’t recommend this frame for anyones first build, but if you’re comfortable flying high octane builds then you can’t go wrong here. All in all I’m pleased with the value and performance of this. To the manufacturer, PLEASE beef up the body and hardware kit some, that’s literally all this needs.
