  1. I have ordered an inline volume control cable. I will use it at near minimum volume with my audio recorder, and see if it does the trick 😉
  2. Just to clarify, you attach the recorder through line in - to your splitter from the audio jack in the intercom, and not directly into your headset. Is this correct? And if that's the case, the magic lies in your recorder and setting the input volume to the minimum with no AGC. Thank you so much. You have been so helpful!
  3. Hi, I had a look at your video. Your audio is crystal clear. Please could you let me know, what set up do you use for your audio? Thanks:)
  4. You have any video footage on YouTube that I can watch? I was thinking of getting DJI Osmo 6s action cam at some point.
  5. I am currently using a cheap action cam, Qpix. But what I realised was that the quality of most action cams or dash cams is not very good. I am therefore planning to use my old Samsung S5 for the video, with line in audio as well on the S5, or a separate audio recording with an audio recorder, which I can then sync with my video.
  6. I was planning to do something similar with my old S5, if everything else failed. I use Autoboy app on the phone as it records for > an hour. I was wondering what app do you use, so that it does not stop recording every half an hour. Also, I believe it will consume a lot of battery about 1 % per min, in 720p with screen backlight off.
  7. The problem is with getting a clear audio. My current set up is giving a lot of static which I find hard to eliminate using audacity. I am planning to use my phone audio recording with a TRRS splitter / adapter to see if I can get a better quality recording. I have tried using a ground loop isolator, but results were still disappointing while recording audio from the radio. Another option is to try using a dedicated audio recorder with a line-in facility rather than just a mic option, to see if it gives me any better results.
  8. Looks like a very expensive option. I would rather spend that money on flying.
  9. Hi Everyone, I am looking to record the cockpit audio during my flying. I would be grateful if someone could suggest a proper set up. Currently I have a digital audio recorder of mediocre quality attached via a 3.5 mm adapter pin and splitter to one of the headphone jacks of the intercom. Unfortunately, I get a lot of noise / hiss / buzz / static which is unbearable and almost completely blots out the audio in the recording. It is impossible to hear what is being said, when listening to the recording. It does not interfere with the normal operation of the intercom, while listening or transmitt
  10. Hi Dayble, In case you are still looking for an answer, the J230 cruising at 107 knots is expected to burn 17 litres / hour at 2600 RPM. You can go to the link below and press CTRL+F and type 107 in the search box. It gives a table of RPM/Fuel Consumption/True Air Speed http://adelaidesoaring.on.net/wp-content/uploads/2017/02/J230C_Section0_9_POH.pdf Cheers 🙂
  11. Any reason why one of the cylinders would lose compression in mid-flight?
  12. Hi kgwilson, when I did a few lessons on a Cessna 152, it was from the shortest licensed grass strip (490m), in Netherthorpe, UK. The instructor used to use 10' flaps and called it the "hedge" check. This was to ensure you clear the hedge at the end of the runway. I think it's a good idea to use half flaps so that you can be airborne asap, and start climbing, in case you have an engine failure and need the runway ahead of you. Besides, one never knows, but you might need the runway for a longer than usual run on a hot day or high altitude. I completely agree with rega
  13. I think this makes a lot of sense. The reason you apply take-off flaps is not to increase the lift. It is actually to increase the drag, without affecting the lift too much. This gives you a steeper climb path (if there is such a thing), making it appear as though you have a better climb performance. What is actually happening in reality, is that you are able to climb to the desired height, within a lesser horizontal distance travelled (due to the drag created by the take-off flap). On applying take-off flap in a glide, once again the horizontal distance travelled will reduce (due
  14. The Jabiru lists the best glide speed of 65kt for the J230. Any ideas, if this is without flaps or with half flaps? In my understanding half flaps increase lift, without increasing much drag, hence half flaps should give you better glide performance.
  15. A Jabiru Gen4 engine quit today, and the J170 landed safely in a paddock. No further details available. So yes, the Gen4 engine is not immune to failures. Just not being reported like many other engine failures.
  16. The only problem I see when coming in with power is, I will need to extend my downwind and and final legs, as it will stop me from descending fast enough. In which case, it would take me further away from the runway, meaning there is less chance of making it to the runway if the engine quits. I guess it is a catch 22.
  17. Is reducing to 2000 rpm more ideal, than taking the power off completely?
  18. I have been using a different approach for my regular landing. Once abeam the threshold on late downwind, get carb heat out, power to idle, pitch for white arc / 84kt. 1/2 flap, maintain 80kt, turn base. On base, maintain 70kt, trim full back. If profile is high, full flaps on base, or wait until on final and landing assured. Aim for 65kt over the fence, and then look outside the cockpit to flare and land. A complete glide approach from abeam the runway threshold on late downwind to touch down, unless other traffic in pattern. Only problem with trim full back, is the amount of for
  19. Hi Phantomphixer, what is your trim setting on finals?
  20. Hi, I normally come in at 70 knots, and reducing to 65 knots, once I cross the runway threshold.
  21. I guess, it took me with a bit of surprise, as I did most of my flying in a LSA, and few hours in J160. I guess a bigger 3300cc engine in a J230, means more power = more left yaw = more right rudder 🙂
  22. Besides, it is important to overcome the urge to correct the left yaw with ailerons, but to use right rudder only. Otherwise, it could lead to a cross controlled situation. An increase in angle of attack of the left wing, without adequate right rudder input, could stall the left wing, resulting in spin to the left.
  23. Hi everyone, I recently had an opportunity to fly the Jabiru J230. I had the flaps fully extended, power off and speed about 70 knots on finals, with the trim set fully back. As a part of normal touch and go, I applied full power and noticed the aircraft yaw to the left and pitch up suddenly. I immediately corrected this with a boot full of right rudder and lowering the nose. However, I was caught by surprise, and in aviation surprises are not always pleasant. As soon as I had the nose level and speed of 80 knots, I raised the flaps to 1st stage (take off) and set the trim to neutral.
  24. The only issue with registering the Jabiru as GA is, that it may reduce the resale value or chances of getting a buyer, as most pilots looking for a Jabiru are RAAus members. It may not be possible to change the registration back to RA Aus.
