Update 4/7/18 - I originally posted this build on 11/2/17 and it has undergone many transformations. The only original part is the camera. I had to replace the frame and I upgraded the rest. F4 Omnibus from an F3 SP Racing, DYS 4in1 DSHOT ESC from separate Oneshot ones. I converted all my qauds to Frsky from Flysky and am using a Tramp compatible VTX instead of the old AKK. I've racked up a ton of flying hours on this one and keep coming back to it. It's now lighter and more compact inside. I ditched all the lights and started using better props. It deserved an update on its page.

Update: Doing power loops in the park and broke the frame in half, both top and bottom plates. Didn't damage anything else but got a new frame and transferred everything. Took off the LEDs since I don't fly it LOS anymore. Everything checks out and it's ready for the park again.

Update: After one too many collisions with trees and the ground a motor died (stator wires came loose internally). Decided to get rid of the budget Racerstar motors with their flat magnets and large gap instead of replacing the motor. Went with some Arris S2205/2300KV motors with N52 curved magnets and a very small gap. Also pulled off the RX that I got free and put a better one on, more suited for a quad. The motors made a huge difference in power, like night and day. Update to update: After a little research I have determined that the new motors are manufactured by AOKFly and rebranded as Arris, they are the AOKFly Fire Pheonix RV2205.

This was my first build. I have a lot of experience with electronics, components and soldering but this was my first experience with building a quad. I pretty much followed the YT beginner's guide by Painless360 with some deviation. I used relatively cheap parts that were tried and proven with good reviews. I didn't have any issues with any of the parts I used but I stayed away from Chinese vendors for quicker shipping and easier returns if I needed to return something.

After building and flashing the FC and ESCs I was delighted when it flew great the first time and hasn't really given me any issues after many flights and crashes. I've broken a few props, snapped some battery straps and knocked off a headlight, but no major issues thus far. I used it to learn to fly FPV and it's been through the wringer a couple of times.

There have been a couple of changes since I took these pictures. I've cleaned up some wiring and changed it from PPM to IBUS. I've also permanently mounted the battery alarm instead of taping it to the top. It's been a great little quad with good power and flies very smooth with no jello in the FPV feed.

I'm now working on other builds and will upload some of them soon.

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..
