Artur’s last build this year is the Helix ZX6 from ImpulseRC, here he shares his impressions and some photos after building this quad.
ZX6 is a 6” version of Helix, it has advantage of being able to carry 6” props but motor to motor distance is very close to the 5” Alien which is really interesting. However, I will be using 5” props on this frame, mostly because of the 2300KV motors I am using. I also plan to use lighter 6″ props such as HQ 6×3.5 props for more speed and the 6” handling. Best of both worlds!
Building the Helix was a blast, only took me about 4-5 hours. I watched the build video by KrazyFPV because this isn’t just a mini quad frame, but rather quite a complex kit so I didn’t want to mess up with Flight Controller or Video Transmitter since I never used those components before.
- ZMX Fusion 2206 2300kv
- Aikon 30A Blheli_s ESC
- Helix Flight controller (supplied in the kit) (Running Betaflight 3.0.0)
- Helix Video Transmitter (supplied in the kit)
- FrSky X4R Radio Receiver
- RunCam Swift FPV Camera with GoPro 2 lens
- GoPro Session 5
What I Think About Helix
- Kit includes a lot of goodies so it’s like a half finished quad
- Good value for money
- Easy to build
- Very good carbon fibre quality, already prepped
- Diamond files included (same as with Alien frames)
- Programmable 5V LEDs included!
- Flight Controller is integrated with Power Distribution Board and is soft mounted (not a structural part)
- Video Transmitter has switchable power (25, 200 and 500mw) and settings can be changed via OSD
- PID values and many other useful things can be changed using goggles and radio transmitter – no need for a laptop to tune the quad in the field
- ESC fairings come with a different colors, so plenty to choose from to make a quad more colourful and less black
- Smart, very well engineered design with extreme attention to details
- Few camera plate angle options and GoPro camera plates included in the kit
- Serial to USB adapter included for flashing VTX
- Very easy to feed the lipo strap between the two carbon fibre plates unlike on some X racing frames
- Shipping from Australia (for now), cost a lot and also Duty/Tax applies to a parcel which increase the cost of the quad
- Only certain ESCs can be fitted inside the fairings (size of an Aikon 30A) so it’s not possible to use bigger ESC’s such as KISS ESC’s
- No option for using different Flight controller other than the supplied. Not necessarily a bad thing, It’s a kit after all
- No option for using different Video Transmitter other than the supplied (Not entirely a bad thing)
- Video transmitter is a structural part of the central tower so in theory it can get damaged quickly in crashes
- GoPro tilt angle is fixed at 45 degree. Very aggressive angle, way too much for the park fliers and even for some racers
- Impossible to adjust the FPV camera angle because lens is tight against the standoffs holding the camera plates together
