Readytosky 150mm FPV Racing Drone Frame 3inch Carbon Fiber Quadcopter Frame with 4mm Thickness Arms

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

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.

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

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

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.
