3 inch FPV Racing Drone Frame

I'm kinda noob with quads, but this is my 4th generation build and after much wa$ted gear, it is now all digital. The analog garbage just caused more crashes due to limited range, lost control signal, poor video and/or telemetry. Since this frame design has a pair of both 30 and 20mm mounting centers, I made this a 20mm stack + DJI vista + ELRS + GPS + Vifly finder. Also AKK 1407-3500K cheapo motors. I even shoehorned a LR2450 rechargeable to power the GPS/vifly for fast hot start. (and longer help find me duration) That's a lot to cram onto this tiny frame, but the 'mini' electronics make it barely possible. (some clever construction too) My overloaded (4S) contraption is why the 1.5mm thick battery hat broke after a minor hard landing. But not totally this frame's fault...I removed the two vertical brace plates that normally are intended for mounting the analog camera -and substituted round standoffs and little rubber camera mounts for the Caddx digital camera. This weakened the frame's battery mount -so I bought a second frame kit and glue sandwiched the two battery platforms together, making it a 3+mm plate. The remaining frame is robust enough to withstand my clumsy attempts to learn to fly -or crash due to inflight motor failure. lol 1 star off for being too lightweight, 2 stars off for durability due to the battery plate, but that's IMHO. In reality, its a 4 star all the way. All part of the fun.

Haven’t got to fly it yet since there’s snow every where but this frame is solid. I have a 5” apex frame and I expect this 3” frame to be just as strong if not stronger. Building it was pretty easy and only took a few minutes to assemble the frame. I think this is going to be an awesome drone and I can’t wait to fly it! It’s a heavier end frame so keep that in mind and expect the drone to move fast with this amount of inertia!

I consider this the BEST beginner 3" frame. It is more durable than anything youll find on RDQ or pyrodrone, but it is not nearly as durable as a proper 5" basher. I love how SIMPLE it is. 1 bottom plate, and 1 top plate - even a 3year old can assemble it. It is kinda heavy, but with 4-blade, 5-blade and 8-blade props, it flew freaken amazing. After destroying 3 of these though, I am off to find something a tad more durable, I give this a 5.5/10 durability on concrete, and about 8/10 if you only ever fly on grass. Definitely worth the asking price, but not 5 stars.

Excellent frame, flies great. I was looking for a frame to replace my Diatone r349 4s, which broke an arm on a hard crash. Wanted something more durable than the 349 and wanted to stay in the 3" range. This came in considerably more heavy than the 349, as the frame is roughly 2x the weight plus I added a vista unit (which I kinda regret- I think I had better overall quality with the micro swift and tbs vtx, lots of pixelation with vista). Weight came in at roughly 310g with a 850 4s battery. Yikes! 1408 motors and 349's esc still provide PLENTY of power for ripping freestyle. With same rates... I notice I need to keep the throttle around 20-30% higher to maintain a hover/cruise. Flight time was around 4-5 min instead of 349's 6-7 min on an 850 pack. Flew absolutely great on my 349's PID tune (courtesy of AndyRC). Will probably upgrade to bf 4.3 and tweak the filters and PIDs a bit more, but as of now it flies better than any of my previous rtf models with shipped tunes. Flips and rolls just seem so much more precise. Overall, much happier now with this frame and more confident it won't shatter or crush motors the way the 349 did. This frame is rock solid. It's given me a new perspective on the importance of a well designed frame. Edit: Ran logs through bf Blackbox viewer. Absolutely no abnormal vibrations/resonance. Was able to turn bf filters WAYYYYY down and motors are barely warm to the touch. Could probably go further, but want to leave some room for a bent or damaged prop should I ever need it. Update: went head first into a metal sign at high speed. Not so much as a scratch.

45 crashes and it’s still going. Has yet to complain or call me names.

Absolutely did not expect this frame to be as good as it is. Wow. Everything fit well and it was easy to build a sub-250gram drone with more power than I need.

Have flown this for a few weeks now with T-Motor 1507s 3” 6S 650mah batteries with some decent crashes nothing crazy but the frame itself is holding fine, the bumper and skid plate not so good they are hard 3D plastic and have broken in different crashes I did make new bumpers and skid plates out of PETG and TPU and seem to work better. Frame is good though for the price to flies good.

Good value bit heavy but i really liked it durable dropped from over 100 feet didnt break several times

Perfect frame for my analog unit and flies just like it should

Wall proof, carpark proof, car proof, bounces off trees. A good copy. And quick to assemble. What's not to like.

Its a bit too small, not 15cm as described .
