We took the DJI Mavic Air out

After unboxing, we really didn’t like the charger… nor the battery. Since the Phantom 3 to Phantom 4, the Inspire 1 to Inspire 2 and maybe the Mavic Pro to the Maciv Pro 2, the batteries have always been redesigned. Nothing is usable after an upgrade. Upgrading your DSLR from a Canon 60D to 70D or upwards to a 6D, 7D or 5DMK2 or MK3 do not require you to change the battery. It all uses the same LP-E6.

Come on DJI. It’s something that’s adding costs to users who upgrade. Reasons of profit or trying to squeeze it into a newly designed body of the drone are simply too expensive for end-users.

We didn’t like the charger either. It has to unfold, batteies stand vertical. The cube charger for the Mavic was better.

Option of the transmitter stick to be removed is good for those longer haul transport/ trip. Careful of dropping them onto grass in the field. A pair of spare is provided but we’ve installed it and has never removed it since.

Wind

It doesn’t handle wind well. Simple as that. We saw it drifting as we were flying near waters and usually what the Mavic Pro can handle, the Air could not. It wasn’t even huge gust of wind to begin with but we have trouble bring it back, lowered it to behind some trees and flew back behind trees.

Asteroid Mode

It is cool but if you were to get the Mavic Air to do one thing, this is about it.

Can you do car chase with it?

In 1 word. Yes, albeit a slow car.

Conclude

It’s small, it’s compact so you have to know the battery life is affected. The Mavic Pro seems to still have hit the balance better of weight vs flight time.

The build quality isn’t fantastic but you pay for what you get. It feels plastic and not as sturdy. We don’t think it’s meant to replace the Mavic Pro. It sits squarely between the Spark and Mavic Pro. Distance wasn’t great but we hit 1.8km easily before getting video signal lost but when back at our regaulr flying field, we can’t manage anything more than 400 meters.

We did some slow 8 to 12 meters/ Sec, car chases shots at 4K. Front and back obstacle avoidance is a great feature. If you don’t own one yet, get a Mavic Air, if not go for the Mavic Pro. By real commercial work, don’t get Mavic anything, look at the Phantom 4 or the Phantom 4 Pro.

The DJI Mavic Air, Mavic Pro, Phantom 4 and Phantom 4 Pro are available from Camera Rental Centre at a limit rental price. Check them out.

Lithium based batteries on planes

In what was problem that was actually caused by the manufacturers, passengers are actually penalised on how much watt hours worth of batteries you can hand carry on board planes.

Watt hours is what airlines uses. We are lucky there’s the Internet. It’s actually not much, for example, we use the popular 5200mAh and 5000mAh 4S lipos.

Converted, they are 76.96 and 74 watt hour respectively.

Convert using this or use

(mAh)*(V)/1000 = (Wh)

Other popular batteries (values are per battery) –

DJI Mavic – 43.66 Wh
DJI Phantom 3 – 68 Wh
DJI Phantom 4 – 81.3 Wh
DJI Inspire 1 – 129 Wh

***Do Not Check in Any Batteries in luggage. Always hand carry.***

Singapore – Cargo shipments of lithium-ion batteries will be banned from passenger aircraft from April 1 to reduce the risk of onboard fires.

Gist of it:

Jetstar Asia – carry on only, two lithium-ion batteries under 101 (6824.32 mAh 4S Lipo) watt-hours each that are part of electronic equipment.

– Only one other spare battery under 101 watt-hours may be carried on board,

  • There are no restrictions for batteries under 101Wh (eg found in mobile phones, laptops)
  • All spare batteries must travel as carry-on baggage.
  • Batteries in checked baggage must have the ON/OFF switch protected to prevent accidental activation.
  • Batteries between 101Wh and 160Wh (eg in medical equipment) require airline approval, which you can request by emailing dg@qantas.com.au.
  • Any batteries over 160Wh must be sent by Qantas Freight (except motorised mobility aids, see below).

Singapore Airlines allows laptops and mobile phones with less than 100 watt-hours (6756.75 mAh 4S Lipo) and a lithium content of less than 2g as onboard items.

But the move will not apply to personal devices that are carried on board, the International Civil Aviation Organisation (ICAO) said yesterday.

The United Nations aviation agency’s precautionary step comes after years of industry concerns that lithium-ion batteries could fuel undetected fires in the cargo hold of planes.

Most airlines now do not allow passengers to check in lithium-ion batteries unless they are contained within personal devices such as laptop computers and mobile phones.

While there have been no serious incidents so far, lithium battery-powered equipment is suspected to have caused a fire in an empty aircraft parked at London’s Heathrow Airport in 2013.

A spokesman for the Civil Aviation Authority of Singapore (CAAS) said ICAO’s latest restriction will be conveyed to airlines and other relevant industry players.

“Currently, passengers are permitted to carry portable electronic devices containing lithium batteries in checked-in or carry-on bags,” she said.

“However, spare batteries, including power banks, are not permitted to be carried in check-in bags. They are permitted in hand- carry bags only.”

Singapore carriers also have their own guidelines, on top of what is now required by the regulator.

On Jetstar Asia flights, those who wish to carry the items onboard are allowed two lithium-ion batteries under 101 watt-hours each that are part of electronic equipment.

Only one other spare battery under 101 watt-hours may be carried on board, said a spokesman.

On Tigerair, passengers may carry on board personal devices with a capacity of up to 160 watt-hours.

Singapore Airlines allows laptops and mobile phones with less than 100 watt-hours and a lithium content of less than 2g as onboard items. A mobile phone typically uses a battery that is less than 10 watt-hours.

CAAS conducts regular audits and inspections to ensure guidelines are adhered to, said a spokesman.

ICAO president Olumuyiwa Benard Aliu said: “Safety is always our most fundamental priority in international civil aviation.”

The prohibition, coming after extensive reviews, is an interim measure until a new lithium battery packaging performance standard is introduced, possibly by 2018, he said.

The latest move has been eagerly awaited by aircraft manufacturer and pilots associations, which have been the most vocal advocates for the new safety measure, he said.

160Wh per battery. You are permitted 2 pieces. Total 320Wh. (That’s 8 x Mavic batteries per passenger.)

“Maximum of two spare batteries in carry-on baggage only”

Smart baggage are allowed as checked baggage provided it meets the following requirement:
  • The battery must be removed
  • The battery must be kept in a protective pouch
  • WH (Watt Hour) of the battery must not exceed 160Wh
  • Ensure the Wifi/Bluetooth/GPS is switched off
  • A maximum of 2 spare batteries in the cabin baggage is allowed*
    160Wh per battery. You are permitted 2 pieces. Total 320Wh. (That’s 8 x Mavic batteries OR 4 x Phantom 4 batteries per passenger.)
