Helix ZX5 FPV Racing Frame
Helix ZX5 FPV Racing Frame
Simply put, the Helix ZX5 deserves an award for innovation in racing frame design. With a square motor layout and a custom designed ultra-compact core, it set new standards for FPV racing frames. In the hands of Australian pilot Thomas "BMSThomas" Bitmatta, the Helix has won both National and International races!
The frame structure is made from durable high quality carbon with chamfered edges. It uses aluminum hardware for most mounting points except the core which uses high tensile steel screws. A lot of thought has been put into the core of the frame - everything fits together nicely with minimal wasted space. The standard-size FPV camera is fully protected by the carbon side plates, the ESC’s are protected by injection molded plastic fairings and the rest of the electronics are out of harm’s way. The FPV antenna has been designed to take strain away from the SMA connector, and the receiver antennas are protected by stiff tubes that keep them out of the prop disc.
CUSTOM FLIGHT CONTROLLER One thing that sets the Helix apart from the competition is that it has a custom designed FC and VTx. The flight controller runs BetaFlight on a STM32 F3 chip, with a low noise MPU6000 Gyro. It is packed with features, among which are 6S capability, built in microphone, built in PDB, LED outputs, ultra-clean filtered outputs for FPV, Integrated OSD and more!
CUSTOM VIDEO TRANSMITTER The 40 channel video transmitter serves as a structural part of the Helix, holding the camera side plates in place. It’s built on a very thick circuit board to insure durability, and can provide a selectable output of 25, 200 and 500 mW of clean video transmission. Power and frequency are easily changeable through the OSD.
These are the component recommendations for this frame:
FPV camera - HS1177 (top connector) (Rotor Riot Swift 2 fits with slight reaming of side plates)
RC receiver - No larger than FrSky X4R-SB
FPV antenna - Lumenier Axii - SMA
Motors - 2204-2207 class motors to suit prop size (19x19 motor base)
- ESCs - Aikon 30A or 30A+ ESC's smaller than 30mm x 15mm x 4.5mm
Very nice, cuts through the air like nothing ive flown before. Handles well, broke and arm though, and since rotor riot doesnt sell replacements, im stuck waiting on the ausies to ship me some here in california. Hopefully the 30 dollar shipping selection will speed things up. Other than that, cant complain. Same old top knotch quality you get from impulserc as always. Love it.
When build vídeo and setup fc?
From Rotor Riot:
The video is now available in the description!
As with everything Impulserc produces, this is a high quality product. The purpose built components and frame fit precisely and produce a very clean build. The streamlined frame gives it good flight characteristics for racing and can easily be tuned for freestyle. I highly recommend the setup Thomas suggested of T-Motor F40ii’s and F30 ESC’s. I’m amazed at the power and speed without smoking my batteries. Even with a GoPro session this thing is still a beast in the air.
A few small gripes though: Getting the motors and ESCs mounted with the arms and fairings is a major pain. The design is good as it protects the ESC but simultaneously squeezing the fairing down and lining up the bolt with holes on the arm and motor takes quite a few tries. Also, you will want to use BLHeli to set motor directions because you don’t want to be taking them apart to swap wires.
The other gripe is not having a choice of fight controller. I’ve been using Kiss exclusively so I now have to learn a whole new FC. Would be nice if they could make a deal and offer a Kiss version. Others have posted videos on jamming a Kiss in but you have to do some significant modifications and end up with something not as clean. Not a deal killer, but would definitely add some interesting alternatives to a really great system.
Lastly, the ESC fairings. Because of their design the fairings cannot accommodate all ESCs. Little Bees and Akons fit but Kiss 24A will not. Again, you could simply mount oversized ESCs on the arms but the arms are kind of thin adding to the probability of damaging the ESC’s.
High quality frame and components
Incredibly clean efficient build
Streamlined frame for racing
Getting the arms motors and fairings mounted
No option for KissFC or 24amp ESCs
Having something designed from the ground up to meet certain performance and handling characteristics gives you the opportunity to know exactly what you’re getting. If you build within its constraints it’s easy to have it live up to those expectations. This frame sacrifices customization for performance and consistency, but in this case it's a good thing. Highly recommended.
