  1. Are you sure you both need Thai police check..? Are you both Thai....? Permanent residence in Australia is usually at least a three part process beginning with other temporary visa applications. Then there is usually a couple of years before permanent residence is even considered. Best check your spelling as well. Errors like this " We had to fly back to Melbouren that same day " will see the application form get rejected and you'll loose all your dosh and have to start all over again from the beginning. Also any forms submitted in Thai have to have English translations done by approved translation services, stamped with the appropriate certification number etc. There are free services offered by the Australian government for permanent visa applications for up to, I believe, something like 10 forms.
  2. JR cable (from controller).......red = positive supply......... brown = negative supply .......... yellow = signal cable 2 core from each esc ( blue and black........... depending on esc brand ) would normally be (but you need to supply a link to where you bought the esc to be certain) blue = signal line and black = negative common.( as above....check with the specs on your esc to be absolutely certain......... you don't get two goes at it if you are wrong) There is no need for the red from the controller to be connected as the controller already has supply and the esc gets it's supply from the battery leads ( heavier red and black cores) I've already shown this above so if you cannot follow it, suggest you get in touch with one of the blokes that fly models up there in Udon. Don't know if the club is still operational, last time I saw them was around 5 years ago, but the blokes will surely be around somewhere.
  3. Looks like it could do with a good deal of maintenance.
  4. If so, I suspect because English is a world wide requirement.
  5. Go back to where you come from. You already know it exists, just learn to live with it if you choose to stay.
  6. Happens everywhere. Apart from that, a few reasons for you to chew on.............. https://glenco.com.au/what-causes-a-light-bulb-to-explode/
  7. As I said previously, show some photos of what you have. Your latest statement doesn't make any sense. Primarily as the 3 motors cables are power wiring and never seen or required any "shielding" If on the other hand you are referring to the "servo" plug, yes, they do many times only run the signal and common ground as the bus power is already there, fed via receiver. There can be many variations so show what you have there........ Example of 2 wire signal below.......
  8. Doesn't sound right....any link to the meter and how it's wired?
  9. Sounds like you upset someone in management at some time...... ?
  10. Would have been a good idea to mention that initially. Best to show photos of the before and after (old and new) so people know what you are referring to. Crystal ball gets very cloudy when info is scarce. Binding plug is a servo plug with a short wire across the two outer terminals.
  11. The one aspect of the driven earth electrode in the MEN system is purely a method to hold the supply voltage at ground potential, often overlooked, ignored or just plain misunderstood by diluties. The majority of any fault current (and hence that required to trip the required circuit breaker) in the MEN system travel back via the neutral conductor, not through the many gazillions of ohms impedence of the crappy old clay soil to a pole neutral-earth perhaps a mile away. In my experience, retired electricians are even more knowedgable and situation aware than any that are current, certainly way above that of a weekend dilute. With reference to steel work in an installation, it might be of interest that it provides little or no addition to the pathway to the general earth mass, being primarily encased in concrete, it is, in fact insulated from ground.
  12. Depth of the driven rod is 1200mm as I showed above with 300mm exposed for Australia and we have some of the world's most stringent electrical standards. If you want to bash in a 2400mm rod then be my guest, it's not going to make any difference and certainly won't hurt. Well, except that you'll most likely split the rod, damage the copper layer and mushroom the end trying to get it down that distance.????
  13. It's not rocket science.( at least not for a qualified lecky) Any check on the main earth would entail tracing the main conductor to the exterior, as you have done. In almost all installs, it is not possible to physically check the entire run, however this is covered with a resistance check of the conductor itself (not the ground impedance) Again, as you have done, check has revealed the earth rod was either never installed (quite possible) or it was completely buried under the ground level and corroded or snapped off due to being unsecured. What should be done, although seldom seen in Thailand, the rod of 1500mm length minimum, is driven into exterior area soil a distance of 1200mm with 300 left above ground. To this is attached the main earth conductor (usually with a tag saying "earth conductor, do not disconnect") either by clamp or stud connection, and the connection coated with a protective coating paint such as Zinc-it. The very top of the rod should then be secured to the building exterior via a galvanised saddle to avoid any mechanical displacement of the main earth conductor. Testing of the main earth is between the rod itself (copper coated steel) via a trailing lead and the connection at the main switchboard with the earth removed from the neutral link. Measured dc resistance should be less than 1 ohm. Either test the trailing lead resistance first and remove this and the meter lead resistance from the final measurement, or use a meter which has the appropriate zero capability with trailing lead in place. Testing the exterior ground resistance can be done with a special 4 lead ground resistance meter but does not apply to commercial or residential installations. This test is usually reserved for installs such as commumications or sometimes hospitals. Your best approach is ensure the earth is done as above, and where applicable (as is 99% of Thailand) ensure men connection is in place. Add to that the use of combo RCBO breakers on all circuits. It is now also a requirement that these RCBO's be of a certain type (not the "days gone by" ac only) In reference to this......... https://www.worksafe.qld.gov.au/news-and-events/newsletters/esafe-newsletters/esafe-editions/esafe-electrical/2023-newsletters/february-2023/type-ac-rcds-banned-from-30-april-2023
  14. But are they? Make certain as if they are LED, some are non-dimmable.
  15. No, they are a wake up to that little diversion yonks ago. Seems you are one of those who will not heed well educated advice, know all know everything, Norm in other words, so go for it and we'll all sit back and watch your stupidity for free.
  16. Yes it does......... Think again...it'll cost an arm and a leg.
  17. Now there is the real problem......... ????
  18. Correct...... proceedure is place the binding plug supplied in the "battery/bind " socket in the receiver.(only one place it's obvious by the markings) power up the receiver with the rx battery plugged into any of the remaining servo sockets..... watch for correct polarity, you don't get a second chance if it's wrong. Receiver Led will flash.......... turn on transmitter and select "bind" in the menu. Wait for receiver Led to go solid then remove battery from receiver and turn off transmitter. Remove binding plug then repower, transmitter first, Led should be solid. NOTE:...........Best to do the binding with at least, all propellers romoved. BTW.......make sure you have the appropriate licence/permit.....penalties for operation without one can be rather stiff...........remember you are operating where manned aircraft fly at times.
  19. Nope.... just digs the hole for himself deeper and deeper, no way back. Some just can't be told and as such get the "label" know it all, know nothing.
  20. I wouldn't start beating your chest and crowing about superiority here when you consider the population of each, Aus 26 million, Bangkok 11 million. I'd say at that rate Aus is not all that far behind.
