After several months of testing, the 3rd generation Doberman racing frame from DMR is available for purchase.
This is the strongest, toughest, lightest 5-inch racing frame we have ever built.
The frame is cut from high-quality, high-density Toray carbon fiber. The top and bottom plates with locking 4-mil arms form a super tough, protective center crush zone that can house 30m or 20m control stacks. It can accommadte 5, 5.5-inch or 6-inch props. Cleanest air is with 5-inch. The Dob 3 tips the scale with a naked weight of only 60g - give or take a gram or two. We've managed to keep the cost to an incredibly low $39.99.

We want everyone to experience what our pilots have been telling us:
“Fast as hell. Tough as nails.”
Incidentally, you can purchase this build for $240.00. If you're interested, Giveus a shout here: https://www.detroitmultirotor.com/pages/contact-us

One thing I used on this build that I really liked are the Race Wires - the CL Racing LEDs - placed between the motors and the ESCs. It made wiring the ESCs easier and will also make it easier to swap out a motor should the need arise. They turn red when powering up and get brighter on acceleration. I've been told they could wash out the camera image, but have not had a chance to test that out since it's too frikken-a** cold to fly.

I only had one issue with the build. One of the ESCs would not activate and couldn't figure out why. After a closer inspection, I found a small crack in the side of the harness receptacle on the ESC module. After a closer-closer inspection I saw that the end pin had been bent sideways causing the crack and the inoperative ESC. I was able to straighten the pin and everything is good to go. The crack is stil there but shouldn't be an issue. The image shows the cracked receptacle.

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..
