Product Review: SteadiDrone QU4D 2014 Quadcopter

Heavy Duty and Stable Flying Multirotor for Aerial Videography

This UAV manufacturer based out of South Africa has set out to make durable, stable and easy to transport designs that run on the popular 3D Robotics Pixhawk GPS Flight Controller and provide smooth footage for a GoPro HERO4 in a brushless gimbal. I think they’re on to something here…

SteadiDrone QU4D 2014

When I was first contacted by SteadiDrone to take a look at their QU4D 2014 I was intrigued by its unique design and beefy construction. When I learned that it used the Pixhawk GPS Flight Controller I agreed to take one for a spin. (Note that you can also choose to get the DJI NAZA V2+GPS flight controller configuration as well).

Being already familiar with the 3D Robotics Pixhawk and its capabilities such as Stabilize/Loiter modes and mapping with an Android tablet and DroidPlanner 2 app, I wanted to see how this quad performed.

The first thing you notice when you take it out of the box is how easy it is to assemble and prep for the first flight. The adjustable arms are easy to unfold and click into position with retaining clips. The construction is plates made of CF (carbon fiber) with an open-cell foam cap over the Pixhawk and telemetry controls and a clear Plexiglas top with the product name silkscreened on top. This helps keep the most critical electronics protected from dust and moisture, yet keeps them cool.

The arms are made from heavy duty CF rods which are strong and lightweight.

The form factor of this craft when fully assembled is a wide-stance X-quad with the weight of the battery off the tail. Although it can also be configured to place the battery square under the craft’s belly and adjust the arms to a true X formation (shown later in this article).

The nice part about the clips that hold the arms stable for flight is that they give under any kind of force like impact with objects or a hard landing – which the design keep your airframe fly-able and the components protected (yes, I found this out the hard way already – totally misjudged my distance from a light pole since I wasn’t flying with FPV).

The integrated 2-axis gimbal is robust and holds your GoPro inside its protective housing, unlike most other gimbals on the market. It’s also adjustable to tweak the balance, but mine came pre-balanced and worked well with the new GoPro HERO4 Black.

At first you might think this thing is over-built for moving a GoPro around in the air – it’s mass is effective to providing good stable aerial footage while hovering in Loiter mode. But switch this beast to Stabilize mode and you’ll have a very fast craft that can easily hold its own with the competition. Enough to create some vibration in the video and make the gimbal work pretty hard – to the breaking point at times. But typically, if you’re planning on shooting acrobatics and wild flying formations with any drone, you’re better off NOT using a gimbal and instead just shock-mounting your GoPro to the frame and shooting FPV style like a fixed-wing craft.

Flying Experience and Configurations

My first flights were done with the help of a couple of my colleagues, Terrence Jarod and Ross Robinson, of – they were flying a couple of their quads around to capture some in-flight shots of the QU4D’s maiden flight. Testing first in the Pixhawk’s Loiter Mode (GPS), it was steady and smooth – yet responsive to the controls. The gimbal holds the camera steady with little vibration unless under hard turns or sudden movement.

The next test flights were around sunset the day I received the GoPro HERO4 Black and wanted to see how well it performed in 4k – flying in the Pixhawk Stabilize Mode it’s wicked fast and super responsive – you can truly feel the power at the controls. The video shows that the gimbal has trouble when under full power and in turns, but that’s to be expected on any craft under those conditions. 

Here are a few clips of these flight tests:

One modification I did was to the foam covering the Pixhawk unit, as I wanted to be able to see the flight control LED – I used a box cutter and made an opening above the LED so it’s now visible when the craft is starting up on the ground.

I also wanted to try to fly it on both configurations and use a larger 6000mAh battery with it to increase flight times closer to 20 minutes, so I removed the back battery plate and moved the battery to the belly of the craft and adjusted the arms to the X-formation. In this mode you definitely get the props in your shot when the camera is facing forward, but shooting at 4K give you room to crop the image as well.

I’m very impressed with this craft so far – very solid and well designed and well-built. You can tell a lot of detail went into its construction and I’m looking forward to flying it with some more accessories and in different scenarios (like mission planning with DroidPlanner 2 software on the Nexus 7 tablet). I will update this article with new content as I have more tests and shots available.
