The Thruster I mentioned has been sold.

Who, me?

I’m just now at airport and took a pic of my hottest head:

Hope you’re right. Over the years I’ve followed the various factory announcements about modifications, including throughbolts, deeper nuts, etc. and read all the counter views…then done nothing. Regular oil and filter changes, managing head temperatures, avoiding shock cooling and feeding it clean fuel have served me well. The head metal inside the tapper compartments is still a healthy colour and there is no evidence of fretting or oil leaks.

A neat laminated prop:

Glen this topic could take up a whole thread. A lot of people have made their own cooling setups for Jabs. I know of one bloke who painstakingly refined the interior of his ducts until all CHTs were even and safe. The factory is reported to have tried traditional plenums and decided their fibreglass ram air ducts were better. I like the ability of fibreglass to mound closely to engine contours to minimize leaks. The forum had a pic of a neat one which encase the whole top of a Jab engine (just wasted half an hour trying to find it). My fourth version is sheet aluminium and encases the spark plugs and brings cool air to the whole length of the steel cylinders. On climb out the hottest CHT sometimes nudges my 150C alarm, then stabilizes between 130-140C on cruise. Ground testing with my multimeter probe makes me reasonably confidant of those numbers.

The sock is usually near the centre of most airports, so it might be far off and hard to see during your final approach. Another reason to have a bit of reserve energy up your sleeve in case of unseen wind gusts.

I guess that’s why several laminates are normally used.

A fearful situation, Nev. Rotax engines seem to have in-built protection against the engine being ripped out by massive out of balance situations- their carbs are not clamped on and just fall off, stopping the engine pretty quickly. I have a rough approximation of that: a cable around my carb designed to rip it off if the engine moves too much. Might work. Nice to know.

I’ve read other accounts that the Japanese had in the order of ten thousand aircraft, but not necessarily all operational. That’s the conventional justification for the use of A bombs, but a much more plausible version challenges this. The US firebombing of Tokyo and other cities killed far more than the A-bombs did, so the the loss of two more cities did little to convince Japan’s wartime leaders to throw in the towel. What really got their attention is when the Soviet Union declared war; years earlier Zhukov had inflicted massive defeats on Japan’s army and they knew that the Red Army was now a massive, unstoppable juggernaut. Worse still, they knew what the Bolsheviks did to the Russian Royal family. Surrender to the Americans and their allies was preferable to a Soviet invasion that would have deposed and possible killed their beloved emperor.

Off Topic: The Trump Presidency - an analysis

The Trump Presidency - an analysis

My windscreen is overdue for replacement, but the other bloke flies from his black soil strip. Other members were grounded by the recent rain, but he has big wheels; quite a bit of his farm ends up stuck to his plane.

I saw a neat fibreglass prototype single seater in the Jab factory at least a decade ago.

This morning Quirindi Aero Club had a long-planned Open Day to shake a few would-be flyers out of the undergrowth. A small investment in radio and newspaper advertising brought several new faces to our monthly BBQ breakfast. Visitors got to talk to pilots and inspect the variety of aircraft that had flown in. Several also went up for a TIF around the district. We had three instructors in attendance, flying a Sting, a Tecnam and a Cavalon gyro. In the crisp morning air the heated seats of the Cavalon and Sting were a big hit. It looked like aviators are becoming soft, but this was offset by a hardy young bloke arriving in an unfaired, open gyro after flying an hour from the west. He wouldn’t let go of his hot cuppa. At first light I flew east to video the snow on the hills behind Wallabadah; my dodgy efforts are below. Meanwhile another member did a much better job of capturing 693FA2F8-8A27-4FC0-9F17-AB120B562283.MOV IMG_0402.MOV IMG_0402.MOV 693FA2F8-8A27-4FC0-9F17-AB120B562283.MOV the snow-covered Liverpool Range to our south.

I removed mine yesterday, using flat screwdriver blade to move the clip. Easy to get to on the four cylinder engine. Glad I did, because it had some fine, dark sediment in it. Never found anything in the bowl during the decade I burned AvGas. Now that I’m using Shell 98, I’ll make a habit of regularly checking inside the bowl, plus running it dry to shut down.

I’m impressed by those mass-produced tornado bunkers we see buried in Midwest backyards. A few Aussies have installed similar shelters here to survive our massive bushfires.

Some bicycle gear works well with our little aeroplanes but not lights and horns; we need many times the brightness and range. My favorite bike shop once found me a great little bicycle horn that they thought would be ideal for the plane. I got them to blow it while I stood 20m away. Ear-splitting to those nearby, out in the street I could barely hear it.

No. White dual seat T300.

I know of a Thruster for sale.

Good grief, F10. I have enjoyed your posts so far but this one is surely tongue rammed firmly in cheek... How can you believe anything this serial liar says? (Agree with your first few words; perhaps this discussion belongs on the Off Topic site.

One member of my extended family grew up on a large NT property and told of many adventures with the station aircraft, including using a berm to “bump” it off the ground.

Quite likely, iBob, but that shouldn’t make a difference, because these tools are designed to handle smaller rivets than the 3.5mm ones I mostly use.

In the last few years this site has hosted lots of discussions on fuel types and some of our more knowledgeable contributors have pointed out the quite different chemistries of AvGas and MoGas. Some have warned against running a “shandy”. I’ve recently switched to car fuel, so keep 100LL in the RH wing tank and Shell 98 in the left. The original plan was to start and takeoff on AvGas and swap tanks for cruise, but since Covid, I haven’t had anywhere to cruise to, so that AvGas tank hasn’t been topped up for a year or more.
