This iks quite a unique helix because of some of the components. As I have 8 helixes I thought I would shed some light on some of the changes.

First of all, don't get me wrong, the HELIx is a bloody great racing quad.

However the VTX has a somewhat flaw, it cant take really big hits or the connector breaks off the VTX. I soldered antennas directly to the boards for a while but signal was never the same.

I then changed to a Matek VTX and ran the HD pod so it fits. Another option is running the Unify NANO and you might be able to get it in the race pod.

I then can use Smart Audio to change channels of the VTX with my Taranis.

The antenna is also quite greate, it can be mounted on an arm or at the top like in this picture.

The 3rd upg;rade is the Preadtor camera. Generally only the HS1177 cam fits however its quite dated now. I made this video on how to fit the Predator in the HD pod here -

Any questions let me know!

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
