You mean this one on the normal kind of heavy Ute?

The normal kind of heavy ute. Chev Dodge Ford etc would have needed a reconditioned engine by that ,mileage and plenty of tune ups Plugs and points. They put out puny power compared to this new stuff and  just drink fuel. No  power steering and pretty ordinary brakes. You just wouldn't drive one these days.  Nev

[spenaroo]

replacement instead of reconditioning has been the go to for years, we live in a disposable society

how many engine and transmission shops do you see now? its a lost art.
I know when I was working with Jet-Ski's there was only a handful of guys left that could bore a cylinder block.
and they weren't using new machines. only reason we were boring is new jugs weren't available

look at what the guys in the USA are doing with Holley carburetors,
bolt on fuel injection kits is now the go-to instead of a rebuild.

as for pricing, 
that's where I used to earn my $$$ as a Parts Interpreter.
a good guy can cross reference and get alternatives "same, same but different"

There's plenty of clues there turbs If you had read it, that I'm referring to Old tech.  Nev

Mechanics ! .

Diagnosed a broken " valve spring " as " hole in the head " ..Nrma couldn't get a wheel off a " Commadore sedan ". Next doors Mazda had multiple flashing lights that didn't make sense on the ' obd2 unit ' so mechanic said , " it needs a new motor " .

Actually needed NEW BATTERY TERMINALS.

technicians....

the wheel one is pretty common.
plenty of people with special lug nuts - who have no idea why they give you a socket and don't leave it in the car

My Ducat runs a 55mm double hex head (12 point) rear wheel nut....
not the easiest socket to find, only 2 local shops have one. (I know to call ahead and ask before booking it in - made a puncture repair last year an issue till I figured out who were the Ducati specialists in the area)

i would not be too quick to write off ice engines. electric has a long long way to go to even come close to replacing them. that pipestral electric trainer is a good example.

140 kg in batteries and 25 minute flight times.

Expand  

50 minutes PLUS 30 minutes reserve.  Where do you get 25 minutes from?  Also the weight is wrong ?

Anyway rather than look it up, just make it up instead, its easier.

[spacesailor]

Just by . one litre = one kg = 140 litres of fuel .

At 6 litres per hour , it equates to a loong full day's flying in my " Hummel bird " . LoL

I was one - Flew for 10+ years using Speco engine gauges - they were great. In that time I replaced one gauge - no pain in the pocket.

Chinese ASI, ALT, Compass, VS - US slip ball (tilt gauge) - all good.

US transponder - cost a fortune to replace.

Australian transceiver - Great  (don't actually know it was made in AU)

 

The reality is that for Day VFR, all the certified stuff is way over specified.

speco . that brand brings back memories.  remember when young blokes used to remove their 3 on the tree and fit a speco floorshift from repco.

There is one at our airport and it does 50 minutes of circuits.

[facthunter]

If the conditions were challenging, 50 minutes would be more than enough.  Nev

The aircrafts purpose is abinitio training, remember there is no run-up, or warmup, you taxi straight to the run-up bay  and do all of your talking for the upcoming flights with the engine basically off. It works out cheaper because you are not paying all of the ground time and warm up time. 50 minutes of circuits is basically 90 minutes in the aircraft for a pilot doing his first let's say 10 hours.

 

For this mission and purpose I would say they are ideal. The other benefits are much lower operating costs although when you factor in battery replacement in reality it is only about 30% cheaper than a gasoline powered aircraft. The big benefit is reduced or almost zero noise impact at the airfield so you can start your circuits at sparrows fart  and not wake up any of the locals.

 

 They are not perfect yet, far from it but they are certainly knocking on the door of the future.

Battery powered " Hot air " balloon " .

I can't believe they are SO noisy with gas jets .

question:

how does an electric aircraft do PFL's
I assume unlike a normal engine. the prop can be completely stopped as there is no "idle" setting

That Swedish flying school may be limiting the flight time to 25 minutes because they need extra reserve for some reason.

Battery technology and battery management systems have improved dramatically in the last few years. CATL the worlds largest battery manufacturer are saying that with appropriate battery management & conditioning the 64kWh battery in my EV should reach 1 million km before degrading to 80% of its original capacity. The car won't last that long. So if this technology is available for training aircraft then battery replacement will not be an issue.

[facthunter]

An electric motor has nothing to absorb energy unless it is in the regenerative function and may also have no reduction gearing, so you could practice what you like with it's switching.   Nev

batteries need to improve a lot yet. range and weight are the holy grail.  i wouldn't like to be in an electric plane during a battery fire either.

the only thing I can think of is that extreme cold temperatures are reducing the flight time but I remember reading that if the battery was warm from being recharged then it had no effect on the endurance. If the battery had been recharged 3 days ago and the aircraft had been in  subzero temperatures since then then yes they would be a reduction in the endurance. I don't imagine however any flying school leaving these outside for any length of time. Perhaps you mess read the article and it was 25 minutes in the training area or something like that. You can download the POH of the Internet, I did this some time ago and it was an interesting read with some new conceptual ideas on how to fly an aircraft

Hey that's a good point.
does this mean we get reverse thrust by spinning it backwards on landing?
maybe negating the extra weight of the batteries - compared to having burnt off fuel?

It was in the video that you must not have looked at.

Now I misread an article.

Last week you said I made it up.  I will block you . I suggest you do the same to me. See ya.
