Maybe it’ll finally be easy to reach some fields in Tuas

With the Tuas West Extension opening soon in end of 2016, we hope to be finally exploring Tuas as a flying alternative.

These may not be the location and only based on what is described below and plotted.

– Fully Elevated line
– 13.5 km long with 2 legs: Tuas West Extension and Tuas South Extension
– Total 6 stations and a depot
– West Extension is 7.5 km long with 3 stations plus one interchange station with South Extension.
– South Extension is 6 km long with 2 stations, a future line.

EW30 to EW33 will be on Tuas West Extension to be completed in 2015. EW34 and EW35 will be on Tuas South Extension, a future line.

EW30 (the next station after EW29 Joo Koon) will be the interchange station of the 2 extension lines. EW30 is proposed to be located along Tuas Road, near the junction of Tuas Ave 3 and Gul Circle. EW30 will be at least 20m from ground level.

EW31 will also be at least 20m from ground level, it will be build around 8m above a proposed road viaduct along Pioneer Road. EW31 is proposed to be located above the Pioneer Road viaduct near the junction of Tuas Crescent and Tuas Avenue 2.

EW32 is proposed to be located along Pioneer Road near Tuas West Road.

EW33 is proposed to be located along Tuas West Drive near Raffles Marina.

State of the hobby

It is end June 2016. A round up of what is the current status of multicoptors to us.

We’ve always love folding quads. Just look at our fleet. 30 builts later, we’ve partnered up and now flying Phantoms and Inspires do make us ponder and wonder.

The neatness of these ready to flys. Less hassle of packing things. We primarily fly for aerial videos and photos. Seldom fpv racing/ mini quads. We have a few (See our fleet) but its just for speed and fun mostly. It also means less things to be messing around with. Gains, programming knobs, it’s great knowledge but the hassle with so many China based made with crude documentations, don’t get us wrong, even leaders like DJI has manuals that seems written by school students but they’re getting there…slowly but surely.  

 

 

Being able to push out products in a lot shorter time frame and putting in technologies that they heard feedback from is critical. We all don’t need that new iPad or iPhone, that new Android tablet or new graphic card or cpu,it however makes your competitors play catch up.

Gimbal
Even powering up our good old Phantom 2 with a Hero 4, on a H43D seems a hassle now. You power up the Phantom 2, the Hero 4, connect your antennas to the Black pearl monitor, turn it on….

With the Inspire 1 or Phantom 4. Power up, connect iPad/ your phone, wait for GPS, fly, enjoy the scenery.

Auto Modes/ follow me, circle/ polar
It’s ridiculously easy with the DJI Go app for the POI or follow me.

We love to DIY. The smell of solder get us going and the ability to mix and match motors and ESC and learning the different Flight Controllers can be both fun and frustrating at the same time. If you’re the casual flyer, do not hope to purchase one but hope to have an aerial shot of your holiday or a one off shot of your loved ones having fun flying a kite or spending a day skating, consider renting as even buying one has some maintenance to be done. The least is the firmware updates for your drone and at times, all the bits that come with it, the batteries, gimbal, camera etc etc may all require update(s).

Another important point is, on tiny Singapore and with strict DJI No Fly zone implementation, we weren’t able to take on some past assignment with the church sitting on the edge but inside the no fly zone. On Google Map, go to 1.373587, 103.898441. From the church, you have to fly past 5 blocks of more than 12 storeys high buildings, cross a river and then a forested area of about 500 meters even then, you’re only at the edge of the airport. We needed the church tower video-ed and it’s no more than 20 meters tall…the solution? A DIY hexacopter.

There’s even guys who are certified circumventing this by disconnecting their GPS from their Inspire 1 and fly it in ATTI mode. Go google…

We hope one day, DJI will release what is in the DJI Go app to any Naza DIY-ers that they can build and making the geo-fencing a little more flexible.

Till the day comes and for all commerical jobs we received, seems like mostly, Inspire 1 and Phantoms prevail…for now.

Toy shops selling drones

 

Recently we were on flying assignment that requires us to move around a few locations. At a location we met a fellow drone flyer at a field. He was flying a Syma he said to have got it from a toy shop. His first drone, he proclaim. Then he went on to complain about how lousy it flies then he flew it and showed us. It scare the shit out of us. There is basically no control and it ascend on its own when he had it on the throttle at middle position. He held it out and showed us. It kept going up then it crashed after hitting a tree. Thank the gods there wasn’t any children at the playground of this hot afternoon.

Toy shops not knowing what these are must not be trying to make a profit and sell these drones. We visited the said shop and there are a lot of models. Traditional toy shops know nothing about drones, it’s care, repair and most importantly how to operate it safely. It’s not like the trucks and cranes or dolls and action figures they’re selling. These don’t crash or drop out from the sky and hurt or worse, one day, may have someone, a child no less, lost an eye ball a finger or… get killed.

He ended his day after we let him tried out the Phantom 4 after some explanation why it is dangerous, how it is dangerous and how to have fun, real proper fun with the Phantom 4. He was real happy and say he’s getting a “DJ”. Yes, that’s what it’s known to him, a dji Phantom to him. We told him in the meantime to look at renting it from us and left him out contact and website address. He’ll be back, we’re sure of it and we look forward to have him enjoy one with some shots of him and his kids and wife having a good time, safely.

How a crash looks like in Flytrex

 

Flytrex is a great, cheap and lightweight tool to help, to a certain extend see what may have gone wrong. It doesn’t however include input from your transmitter.

An example below from a crash, speed and altitude has a sudden drop within 2 secs. It’s regardless there is no other logging as the crash was caused by a broken propeller mid flight after reviewing the onboard video footage.

crash

Comparing, a normal flight does not have erratic lines or a sudden fall in speed and altitude.

normal

Simple analyzing of these cannot really help in determining if it was pilot input error but does help somewhat.

Lithium based batteries on planes

Created 2 March 2016
Reviewed – 28 Dec 2017
Updated 2 Feb 2018

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.)
