Building on the features of the original Kratos, designed by Bulbufet/Nurk, the KratosFS takes the best features of the Kratos and packs them into a awesome freestyle package. The VTX and antenna mounting plates remain very similar to the OG Kratos, but because this is a drone designed for a top-mount battery, we've had to extend the length of the top plate. Doing so required a slightly longer tail, which meant that the rear strut was going to be hard to use. As such, we've given the KratosFS a tail with a zip-tie mount that holds your antennas out of danger. A stubby antenna will offer even further protection. In addition to keeping the back mounting plates, the philosophy of keeping the camera as low as possible into the prop line has remained the same, and we've totally re-vamped the camera plates. Designed to fit the RunCam Swift 2 (with the secondary rotation screws), the plates will not allow your camera to slip in any crash or hard landing. Built into the camera plates are two "horns" that come out the top of the frame. This is intended to be a GoPro Session 5 mount; it allows you to strap a GoPro on without the weight of a TPU mount. BUT don't worry -- if you prefer the protection of a 3d printed mount, a TPU protector will be available that interlocks with the standoffs that hold together the horns, making for one of the most secure GoPro holders we've ever used. Finally, one major issue with the OG Kratos was a fault line at the front two arms. This fault line has been removed, and the frame is no longer unibody. Instead, it's two separate sets of arms that are sandwiched together by two plates creating a 7mm thick center mass that still allows bottom mounted battery straps to be passed through.

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..
