Light weight and stong
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!

mixed feelings – maybe not for beginners
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

Tighten the folding arms so they won’t fold or vibrate
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.

Direct swap for broken flywoo explorer frame.
⭐ Explorer-Style 4-Inch LR Frame ReviewBroke 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 standoffsVTX standoffs and screwsELRS & VTX antenna mountsBuzzer mountAlso 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.

Almost an lr4 without the plastics
Almost identical to flywoo lr4. Rear is a bit shorter so thangs can tight. No props in view.

Don’t like folding arms
Very weak design wouldn’t buy again and I stopped using it. Just a useless piece of trash sitting in my junk pile collecting dust. Don’t waste your money

Fun little build – can’t wait to have it up and running!
This was a fun build. I had to go by the pictures for the assembly, but it was easy enough. I am excited for this build.

Ultra Light Frame
This frame is under 40 grams and perfect for sub250 4-inch builds. Great design, print files are available for this frame (open source version)
