Rotor X Atom – Review

The RotorX Atom is a 122mm Motor to Motor sized micro quadcopter from RotorX. It runs small 75mm props, so even standard 3” props will not fit. However, do not be fooled by this small craft, it still packs a huge punch.

Frame:
The frame is made from 2.5mm carbon and a 1.5mm top plate. It is, as you would expect, a unibody design. The configuration is more like a ‘deadcat’ than a typical H quad, despite this we have yet to see any handling issues. The quality of the carbon is good and all the cuts are clean. There are proper metal standoffs for the front 2 posts, which we think is vital especially if you crash hard directly onto a tree or post for example.

One of the biggest issues we think with the Atom is the use of a Naze32. We dislike this as it does increase the Motor to Motor distance slightly, and also weighs extra. In crashes the proximity of the wires means that they can easily get caught in propellers and fixing the damage can be a time consuming process. However we do see the upside of having the Micro USB Port instead of having to use an Adapter if one was using a MiniNaze for Example

Assembly:
We knew we were getting into a hard build when we got the Atom, but we didn’t think it would be that tight. We were completely wrong, this thing is a very tight build and you really do need to be an experienced builder to have any chance of building this thing. To make the build easier we purchased a Genix PDB. This significantly improves the build in our opinion. As it means the Naze is easily removable, instead of having to painfully de-solder connections every time you wanted to remove the Naze. Most importantly, it means you don’t have to run a parallel harness in order to all your ESCs, which we are not a fan of as one of our friends fried his ESCs doing this.

The hardest part we found was shortening the motor wires enough to be able to fit the ESCs on the arms. However this can easily be combatted by simply wrapping the wires around the ESCs then soldering them to the pads on the ESCs. Apart from that, all that was required was precise wire lengths from the ESCs to the PDB, and we were ready for the Maiden.

Flying:
For us this is by far the atom’s greatest strength. The portability of this thing means that even you can shoot the smallest gaps, whilst still holding your own on the even the longer racing courses. The 1306 really make a difference on this regard, and we don’t think that if you used 1104/5 you would be able to compete with the 180/210 class of quad. On the other hand the 1104/5 exceed at backyard flying, and to an extent indoor racing. However we do prefer the 1306 combination as it does give you the best of both worlds.

Overall: The Atom is a pain to build and you do need to be a skilled builder in order to make it. However, if you can get it in the air we are willing to bet you will not have more fun on any other multi-rotor. It is truely a fly in any place kind of quad and flying it on 170 FOV makes you feel like a fly, the complete lack of any momentum makes for an incredble overall flying experience!!
