This is my Armattan Bobcat Analog Build. I started out putting in an FS Digital VTX, but after adding it, I saw it had the same static issues as my previous build, so the VTX might be defective. I couldn't find any TPU protection parts so I ended up having to make them myself. I went with the GoPro Session version of the camera holder, because it was the easiest and quickest to make, but I'm planning on putting my GoPro Hero 8 on the quad, once I design the case.

Nice Build! How do you like those motors?

I took it out today and was able to get about 10 minutes flight time, without battery tunning. After charging the battery, it only charged to 1217mah on a 3000mah lipo. So I have some tuning to do. At first, I thought the motors weren't even spinning because I couldn't hear them, even through live audio, until I pushed the throttle. They are pretty quiet. Flying was pretty smooth, almost gliding. I'm pretty happy with these motors for long range.

Thanks for the update! Was that with the external action camera onboard too? The Li-ions do sag a lot, I have found that you'll be tempted to land early and have done a few tests where I stayed close by to determine the point at which they fall off completely which for me is usually right at under 3v per cell.

Yeah, that's with the GoPro Session camera onboard. Thanks for the info, I'll need to do some more tests to see how far I can push the battery. 3v is a good start.

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..
