This machine perform the best with 3S 400mAh – 450mAh LiPo. Ovonic is a reliable battery manufacturer that can provides high quality 3S 450mAh LiPo battery for this drone

Radio receiver:

It’s a plug and play model, so you’d need to install your own RX. The R239 already has a cable soldered to the FC, which can plug straight into the Frsky R-XSR. That would be my go-to receiver option if you are using a Taranis.


It’s quite a bendy frame, and speaking from experience this might introduce bad oscillations. I am hoping this is less of a problem for a micro quad of this light weight.
The plastic frame provides excellent protection to the electronics. But due to the flexible nature of the frame, when you hit something hard, your propellers might take some impact as well and get bent. Therefore it’s a good idea to get spare props.


The camera is a Runcam Micro Swift V1. This must be a special edition because it has a green case I’ve never seen before, almost mistaken for a Caddx 🙂 Camera is well protected by the frame.
The FPV camera tilt angle seems to be limited at around 20 degrees as you can see in the picture. The frame/camera slot allows for a higher up-tilt, but there is no more room between the VTX and FC stack.


On the back of the camera we have the Runcam TX200U video transmitter, which is a 25mW/200mW VTX with Tramp Telemetry capability. With this feature, you can change VTX settings using Betaflight OSD as well as Taranis LUA script


Motors are the Mamba 1105 5500KV, with Gemfan 1940×3 props. All the installed and spare screws have loctite on them which is great touch. It’s good to finally see some “proper propellers” rather than “toy grade” props from the last version.
