10 things that could save your drone

10 things that could save your drone

If you’re interested in drones you will have no doubt seen all the spectacular crashes on YouTube and heard about drones flying away by themselves. Drones like the DJI Inspire 1 or Phantom 3 are highly complex devices that rely on various systems to perform properly. While there’s no way to guarantee against a hardware or software problem there are a few things you can do to minimise the chances of crashing. Here are my top tips that could save your DJI drone.

1. Know when and when NOT to calibrate the compass

A lot of people recommend calibrating the drones compass each time it’s flown at a different location. While this seems to work for some I think it introduces unnecessary risk. Let me explain why…

When you perform a compass calibration you’re letting your drone test its surroundings for magnetic force and once the calibration is complete it stores that data and assumes that those forces are normal for the current location and will be consistent throughout the flight. But what if there’s a large electrical cable or metal pipework buried below the paving you’re standing on? If that were the case then the calibration you’ve just performed will have taken those effects into account and the moment the drone takes off it will be flying with incorrect compass data.

Unless you’ve travelled a long way (hundreds of miles) since your last flight there’s no real need to re-calibrate the compass if you already have a good calibration locked in. If you find yourself in a nice open undeveloped area then it’s a good time to grab a clean compass calibration, otherwise why replace a clean calibration with one from an area where you have no idea what unknown forces are at play.

DJI Phantom 3 vs Inspire 1 – Which should I buy?

inspire 1 or phantom 3

I’ve owned my Inspire 1 for over a month now and with over 70 flights under my belt I feel like I’m starting to know it well, both from an operational and flight characteristics point of view.  Before i purchased the Inspire I spent a lot of time deciding between it and DJI’s other popular offering, the Phantom 3 Professional as both have 4K cameras and a lot of features in common. I wasn’t able to test either system so I based my purchasing decision on a few factors that could potentially make a difference. The things that really swayed me towards the Inspire was it’s ability to rotate the camera, the removable gimbal allowing for future upgrades and the ability to operate in higher winds.

Recently I’ve had the chance to spend a few weeks flying the Phantom 3 Professional so I thought I’d share my findings about whether I made the right choice and try to give some advice to anybody trying to decide between  these two platforms. Firstly I’ll describe some differences in the aircraft and then I’ll go on to talk about my findings.

Size, weight & build.
By far the biggest difference between these two drones is the size and weight of each design. Although I’d seen a few Phantoms in the past I’d never actually used one before and after using the Inspire for a few weeks I was quite surprised how much smaller and lighter the Phantom is. The Inspire weights in at 2.93 KG whereas the Phantom 3 is less than half that at a mere 1.28 KG.
