That is what I do now. I do have the luxury of long enough runways to do that. It may not be feasible for short field landings, but I avoid those when I can. "Your speed has to decay somewhere, so it might as well be a foot off the ground," Agree totally ... up to the point you're in danger of running out of runway. But then there is the GoAround option.

Thermals can account for these gusts on relatively calm days. What feels like a crosswind is a thermal off to the side sucking air across the runway. You felt in a 172. In lighter planes (ULs and LSAs) it can be more pronounced. In addition, these gusts can catch you out if you don't watch your airspeed close enough. I had one drop my airspeed 10 knots while landing and because I had let the airspeed decay a bit, the drop in airspeed put me into a stall and the left wing started to drop. My aircraft has very benign stall characteristics so I was able to quickly recover with full throttle, and nose down correction. If I had been flying something with critical stall characteristics like one of the scale Spitfires, I probably wouldn't be here today. Now I monitor my airspeed in the circuit VERY closely.

What Walrus said, or worse, what happens if a lump is dislodged at 200 feet over trees at the end of a runway on takeoff.

Yeah, He outsmarted me ... and himself!

Had a bloke ring me and talk to me endlessly about an airplane I was selling. He asked lots of questions which I patiently answered. Further down the track he said he wasn't really interested in a 19 reg plane. I wished him well in his plane search and thought no more about it. Fast forward a month or so later after my plane has been sold, I bump into the guy in a flying school nearby and he rips me a new one for "blowing him off and being rude"! I couldn't figure out what was the problem until I probed him a bit and when I wished him well on his plane search, he took that as "blowing him off" after he basically said he wasn't interested in a 19 reg plane. I asked him why he said that when it was apparent he REALLY wanted the plane. He said words to the effect that "He didn't want to come across as too eager or I wouldn't negotiate on the price". He certainly came across as "not too eager". In fact he managed to make "not too eager" sound like "not interested at all" and ended up missing out. You can be too clever by half if you really try...

OK: Great footage of the snow and not too shaky IMO, but do you ever clean your windscreen? Looked like some mega bird plop on there!

KGWilson: I think your suggestion of a new radio is the go. I had a trike with a rev Q microair radio and I'm not a fan. A really good sub that will fit in the same hole is the Trig.

We went to the Mother's day brekky fly in at Gatton. I commented on their lack of organisation before so I won't get into that again. This flight was the first one with a new GPS recorder I designed and built, based on an Arduino. It stores the autopilot data sent out of the GPS's serial port. I then use that data to create info overlays in a 3D graphics program called Blender. Then I bundle it all up in my editing program, Davinci. All the software is free to download. I will be making a series of videos in the future about how I did this. In the mean time, have a butcher's hook at the end results and give me your feedback. Was it worth the effort?

Yes, that is correct. Here's a pic of my recorder.

I use Lightspeed Zulu 2 headsets Garmin gtr 200 radio A digital audio recorder (iRiver brand?) bought from JB hifi a long time ago A 1 to 2 splitter. Where my headset plugs in that taps off to the audio recorder plugged into ... The line in socket of the audio recorder with the input volume in the recorder turned down as low as it will go. I was just lucky that the recorder doesn't have AGC (as I mentioned in my earlier post) on the line in input. BTW, I see you're location is listed as Wolongong, so here's another video for you... https://youtu.be/RgKlpDKuoC0

Want videos? I got plenty for you. Try this one to start https://youtu.be/Hh_I6W5vpAY

I agree that a good quality noise cancelling headset is a must, and a starting point for good cockpit audio recording. But that is not the whole story. Another very important element is to find a recorder that doesn't have Automatic Gain Control (AGC). This is the hard part as most cheap recorders have that feature, but won't let you disable it. The problem with AGC is that when there is no audio present (from speaking or radio reception) the AGC essentially turns the volume up full in an attempt to capture some audio. In a noisy environment all this does is capture electrical noise and cockpit noise. Another source of noise is the power source for the recorder. Analog devices such as voice recorders are very sensitive to power supply noise. The electrical systems on airplanes are notoriously noisy and cheap recorders usually have poor power filtering. So don't try to power your recorder from anything connected to your airplane's electrical system, like USB charger ports etc. Best to run it off its own internal battery. Finally, if you're recording your cockpit video on a gopro, don't try to capture the audio on that by connecting the camera to the intercom system. You can't disable the AGC in gopros and the resulting audio is HORRIBLE. BTDT!!

Brokers work for the broker. Full stop, end of story. Viewed through that lens, it is easier to understand the motivations of the brokers, that is protecting their income by obfuscating rego numbers, selling dodgy stuff with minimal or no documentation, and savage discounting for a quick (and dirty) sale. That is the most important thing, closing the sale. Any problems that arise after that are the buyer/seller’s problems. I avoid brokers and agents like the plague where possible. That also goes for lawyers. I've done plenty of real estate transactions in my time and every conveyancing lawyer has stuffed it up royally somewhere along the line. You have to double check and triple check their work. Which begs the question, “what am I paying them for?”.

Have a look at the Flight Data FC-10. It's about the cheapest one available. What Skippy said is the case. It costs very little extra for a manufacturer to put those extra features in the software. The expensive part is the sensor.

Do you have to ring for PP before landing there? I would like to try that out sometime.

A bit of a mixed bag with this one. Yesterday we went to the Gatton Mothers day “brekky”. The flight from Heck field to Gatton and back was a dream. Smooth as silk even at low levels. The “brekky” was another matter entirely. Officially, it started at 7:00 am. We arrived just after 8:00 and they had run out of food already! There was still a queue waiting for food, and, starving, I joined it hoping for a nice hot brekky. After 30 minutes it became apparent the line wasn't moving at all. There were people “cooking” but no one was walking away with meals. After another 20 minutes in line, I saw about 4 people ahead of me walk away with their meals. Then the line stalled again for another 15 minutes with nothing happening. By that stage, I completely lost patience with the total lack of organising and got back in my plane and went home. Not good enough Gatton. If you put on a fly in brekky, you should understand that the people aren't there just to try landing on your runway. If you can't organise the food, then you don't have a “fly in brekky” you just have a “fly in”. I heard from someone that there was a bigger turnout than the organisers expected. That surprised me. A look at the weather the night before told me that there would be a large turnout and the “organisers” SHOULD have seen that coming. Even then, when they had food (I could see people cooking something) it took a very long time between meal deliveries. I've been to many fly in brekkies and I know it can be accomplished even with the uncertainties of weather and the whims of pilots. Also, I've been to other brekkies at Gatton which went well. Whoever did the organising for this one though needs to have a good look at what went wrong, and it wasn't the fault of the number of flyers that turned up.

Fantastic! Thanks for the update.

Yep I did! Thanks for reminding me.

At one stage he was flying directly over the tracks with wires either side of him. Not clever at all IMO

Went to the Watts for breakfast flyin last week. The weather cooperated and there was a really good turnout with some nice formation flying from the Yak crew.

My instructor always told me to “fly in the middle of the air. It's dangerous around the edges” He also used to say that he didn't do low flying because he had a back problem. That usually prompted the question “What's wrong with your back?” To which he would reply “I have a yellow stripe down it”

If the fuel pressure gets too high it could conceivably overpower the float valves. I'm guessing thought that, that kind of pressure would manifest itself in a number of forms. One of those would be flooding the engine with attendant bad running. Another might be fuel running out of the carby vent tubes. Did you have any of that when you had the proper size restrictor? As Thruster said, with the Rotax fuel pump, it will determine the fuel pressure based on its internal mechanisms. You can safely assume that unless the pump is faulty, the pressure would be within safe values. More likely from a defective fuel pump, is low pressure. If your fuel pressure IS too high, the more likely culprit is an oversized boost pump. Check the model of your boost pump and look up its specs against the Rotax specs.

Good stuff. I still think your return quantities bears investigating. From the figures you quoted, it sounds like more fuel is bypassing the carbies than they're consuming and that doesn't sound like it should to me. I'd check that the restricter is there, that it is the correct size, and is in the correct path. BTW, the local Rotax dealers suggest a carby jet insert as the restricter. From memory, it is an M5 thread and will fit nicely in the end of a brass T that has been threaded with an M5 tap. Rotax sell a cross connector with the built in restricter, but it's very expensive! Good luck.

I just reread the fc10 manual. It seems like adding a second sensor should be pretty easy. The cube has 3 wires, 2 are for powering the sensor and the other wire is the signal back to the FC10. The second cube gets its power from the same connections that power the first cube ie, their power connections are paralleled. Then the signal wire for the second cube connects to pin 8 of the FC 10. But now you have two k factors to adjust. One for the supply sensor and one for the return sensor. The K factor is like a “slippage” or fudge factor for the sensor. Since you say you get accurate numbers by turning the return off, I'd guess you have the K factor about right for the supply sensor. If you mount a second return sensor near the first one and in a similar orientation, you could use the same K factor for the second sensor as a starting point. By leaving the number of engines set at 1 in the FC 10 setup, I'm guessing that it will subtract the second sensor's readings (adjusted by its K factor) from the first sensor's readings. HTH
