RotorX RX122 Atom V3 - 4"

I always wanted to build a RotorX RX122 Atom V3 4" frame because I kept seeing great reviews on it. So here it is, a light 4-inch quad that weighs in around 142g - 150g depending on what props you use. Overall it was a pretty easy build with a HGLRC XJB F428 stack because all I need to wire up is the Motors, VTX, Camera and RX. Initially I was using the stock dipole antenna with the eachine VTX03 but it was not doing as well as I hoped so I switch it out to a TrueRC AXII.

As for the props, It all depends on what you want to get out of your Atom. I like the flight characteristic of the GemFan Flash 4052 but it does weight a lot compared to everything else I have tried. Even with the extra weight it still flies very efficiently, I get about 6 minutes of flight time (depending on the way you fly). I also like how quiet the flash props are compared to the 2 blade Dals. However, the GemFan Flash props are a tad bit larger which has less than a millimeter of clearance between the props. As of now I was able to fly it without any issues or props strikes but it is just too close for comfort. Over all this is a great frame, I know it is an older design, but it just works. So, I will be keeping this setup in my collection for a while.

cool quad! Strange they sill call it 122... it's not 122mm at all :D

The build looks great btw. Do you know if the quad is under 250g with the battery added? If so it would be an awesome build for when the new laws are introduced here in the UK next year.

Thanks for the reply. Amazing build and its very likely to be my next. The atom frame just looks great

No Problem, I am sure you will be happy with this frame, it is simple and works great. Only one small drawback.... it does not have too much flexibly with the camera angle. If you have a 3d printer you can print out other camera angles, but it is still a pain to change.

Ok, thanks for the advice

The iFlight XL5 V3 is a fantastic freestyle frame for the price. It features chamfered edges on some very nice quality carbon fiber. My goal for this build was to use high quality components at a relatively low price. Not only that, but I managed to reduce the number of solder points to the bare minimum. I've never built such a plug-in-play quad! The flight controller has an integrated VTX and doesn't..

Update! Happymodel has released a new V2 Frame which uses a more durable plastic. The Happymodel Mobula7 is one of those rare treats to hit the micro scene. Countless models hit the market every month, but this one just happens to check all the boxes. It's a 2S brushless micro with a 75mm motor stance. It's slightly larger than the more traditional 65mm brushed micros, but it's still quite small...
