The Idea:

Basically a beefed up version of the XR-210.
Not many pics yet... The main plan was to come up with a fun flyer that is strong, light (thrust to weight is 14:1), and with a low cross section. A Runcam Split was used to help with a couple of the objectives. You can't tell in the videos, but a nice by product of the design is that it's relatively quiet. Obviously with the motor choice (not much of a choice since I'm hooked on these) I wasn't super concerned with weight. Although the frame is only 50g, AUW is about 455g (considering it doesn't need a gopro strapped to it for HD video, the weight isn't too bad).

DO NOT BUY A CLONE PIKO BLX They have solder quality issues. If you do happen to have one and it starts acting up, chuck it in the oven at 425° for 20 minutes to re-flow the solder. Mine seems to work now, but I have not tested it yet.

Changes:

Arms

I settled on a combo of 8mm and 6mm carbon fiber tubes (slid into each other) for the arms. I will be shocked if these arms break. However, I am rather rough on crashes...

Motor Mounting

The front motors are now inverted. This not only helps with CG/CT alignment, it also takes the props out of the video.

Protection

Everything is enclosed in the body, with the exception of the Vtx, but it is not in a very vulnerable spot (so I think)...

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..
