All I can say is I am now seeing far more poor airmanship on airfields now. It wasnt like that 10 years ago. I am pretty sure it just isnt associated with my home airfield

Had lots of stuff going on in the personal life lately and havent had a lot of time for Mabel. This weekend I have finally managed to complete some important tasks. A couple of weeks ago we got the exhaust system modified so its a nice fit with room for the water circuit and oil..also I dont have to remove the front left header pipe now to change the oil filter During last week the hooks for the springs on the two modified exhaust headers were tigged on also made the stainless rings for the EGT sensors they are also tigged on as well and I have finally fitted the exhaust to its final position. I decided I really like this corrogated stainless flexible hose. it is thicker than the ICP stuff they supply and I feel more comfortable with it. So the water circuit is fitted with it and now the oil circuit. The oil was a bit problematic trying to get hose that fits nicely over the 14.2mm outer diameter of the hose. It needed to be squeezed down to about 13mm to fit the good quaility oil hose I like to use and of course this stuff becomes the joiners. I used a collet chuck set from my CNC machine and used it to crimp down the tube to a size that I can get into the oil hose. It flattens the round ridges to get it to size but I did some tests and it does not affect its strength at all. Got a nice water fitting from Danny's stash pile of stuff so I could get a water temperature sensor in it and that is now fitted. I soldered a silicone wire... the stuff I use for my CDI modules onto the base adaptor so I can just earth that to the engine block so it works properly. Have been wiring the dash and just need to get the headsets run through and fitted to behind the PAX were I will have my fuel switch as like before in the Girlfriend but its a different tank system so only have 2 switches not 4 Concentrating on getting all the wiring from the engine side to the firewall plug then I can wire through to the RDAC and will be almost ready to start the big bore engine Finally got the production version parts in for the throttle mods and they are pretty nice. they tumbled all the parts so look really nice. Also my old tig is pretty stuffed now so lashed out and bought a new one...and ohhhh its nice...one of these automatic setup ones..works a treat. Now I have to spend a few hours in front of my hydraulic press to get all these to shape

Caboolture was blasted about ten years ago on this site by Qerty, an exerienced pilot who flew in on a leg of a holday trip and found aircraft all over the place in the circuit, sub standard radio, gliders actually parked on the strip ALA working on them, with no attempt to move them, and radio standards that were not up to scratch. Well not strictly correct or accurate. Radio??.. YCAB has only just been made mandatory about 18 months ago Gliders on the strip?..just doesnt happen. Infact glider ops are actually made OUTSIDE the full runway side markers and never take place anywhere else and its been that way for the 12 years I have operated at Ycab The issue at Ycab is just too many aircraft ops of all different types. The Ops manual is currently being rewitten and almost finished YCAB and YCDR are on the same frequency as so was Redcliffe back then. Redcliffe got a freq change about 8 years or so ago but that creates problems because they forget to change frequencies when they traverse our airspace which is close to theirs on the way up the coast or over to Moreton Island. YCDR runways were the same numbers as ours 12/30..we tried to get a frequency change but CASA and ASA told us no. So we changed the runway headings to 11/29 as the confusion beytween operating areas was terrible. You would hear a aircraft call the runway but it was at YCDR not YCAB..now its reasonable but hetrodynes are still massive as Caloundra is reasonably busy as well now. YCDR is only about 15nm from YCAB Pretty much all of those accidents were pilot error and most were very experienced pilots inc one that had 15000 hrs plus. It had nothing to do with ops at YCAB..... all pilot error or mechanical failure so you dont get to play that card Turbo

He was probably using his experience to avoid you..just saying. We never get reports about tug pilots ops but plenty of reports on normal pilots and aircraft ops or should I say inops. Airmanship is lacking now days and its very visible. I think this all goes back to the training given now. Its not like it used to be when I started flying back in the mid 1980's. Airmanship was a big part of training. It now seems to be lost. Maybe I might be a old fuddy duddy but there are plenty of people that go and watch the comedy on the boat ramp scenario on sunday mornings. One of the issues is the airfield is now so busy but that still does not exemplify the situation. Students and low time pilots need to be more aware of what they are doing and to me it just doesnt seem to be happening. I am no expert by any means but when I fly I try to make sure I know where everyone is in the circuit by eye and radio. I have had to take exvasive action a few times simply from other pilots not looking or listening.

Manual over electric any day...I hated electric flaps on the GA aircraft I flew...I have done a lot of glider flying and they are manual flaps and airbrakes and all the ultralights I have flown are manual flaps...manual is far better than electric any day

The pistons will come out easily..but the piston itself is not big enough thats why when your pads get low the bloody piston can come out

He isnt sure about the big bore version..he offered me a kit but I would probably have to do other stuff to it...getting the compression right too is another thing so would need sparer rings for the heads to lower compression Our conversation is below. But I have had good feedback from Gyro guys about his conversions. I have supplied my replacement CDI's to the gyro guys I gather you want to put it in a Hornet. I had a guy drop into my farm with a Hornet with a std 912ULS..the perfomance wasnt that great..it does need about 20 more horses and it would be a great aircraft Hi Mark, This would be a one off. I have only done testing on the standard 100 hp with the turbo. Also other considerations like the bore diameter and the current compression ratio would have to calculated. Other companies won't turbo the big bore so I couldn't guarantee how well the engine would hold up. Can you give me some more info on the engine like cylinder bore diameter compression ratio and if the camshaft is standard? Thanks Steve Hi Steve The bore is 4mm bigger and is 1484 cc once fitted. I believe the compression ratio is the same. The camshaft is std. Its basically just replacing the pots and pistons which are 4mm bigger in size. I had the crank welded and the engine has been totally balanced. I understand the differences in piston load etc although the piston speed is the same as there is no difference in the stroke of course. Hi Mark. I could offer you a turbo conversation kit If you have a mechanic to do the conversion. there may be differences in some parts you would have to work out as you go.

I asked him about doing a turbo for a big bore kitted 912 ULS which is a base power of 114hp turbo would bring it up another 15 or 20hp. He hasnt done one like that. Mark

Sometimes you need to put a washer infront of the piston. when the pads get low the piston will pop out

There is a guy in Melbourne who does a lot of 912ULS turbo conversions. Mainly for the gyro guys. Everything I have seen he has all good reports Mark

yes Mike it goes back quite a long way..but RAA have never said anything against it..they just seem to refuse to take up the topic or support AOPA in any way on it....they just keep their mouth shut...for obvious reasons

KG. I think what it is ...that RAAUS has not supported AOPA in their push for it. They basically have stayed quiet everytime AOPA has asked them

My boss was up there a few weeks ago with a drag weekend

I just want to get her finished and flying 🙂

Raeburn..very glad you both are ok

Thanks Bob..I hadnt actually looked into that and it makes sense..also will be much easier to install then..the pilot side allows much easier access

The top is the inlet side thats the pipe than cones down the back of the engine..the hotest water is coming from the pump but that is a little problematic I think to get the connection there although of course its the best place. Dunno will have a better look and think about it this weekend but it makes sense to do so. My RANS S-21 engine is a 2015 that we rebuilt and balanced I didnt think to look now I know its not the same since 2013. The engine is on a engine stand so will spin it over and have a look

I was thinking of just adding a small piece of normal metal pipe inline on the return side and screwing in a LM135 or similar probe in there. I made the temp sensors in the girlfriend Just heated up the old resistor ones and pulled the guts out then wired up a LM135 and epoxied it in there..worked a treat for all my other sensors so that maybe a solution. I think I will monitor the rear one in the head as that is the hotest and the water in the pipe for the second one

Yes I am aware of the slight reduction of ID on the pipe. I have now though probably almost twice the cooling area of the radiator due to the new opening. Having a big bore kit fitted I am expecting more heat. The engine is the pre 2013 so the temp senders measure the head temps not the water temp. I am thinking about fitting some sort of water temperature sensor as well. The metal pipe will also help dissapate some heat as there is a lot of surface area of the pipe when you consider the corrogations on the pipe. Danny was over yesterday and we were talking about how we are going to mod the exhaust pipes. Hopefully next weekend I can get that done and if I get my backside into gear this week I will have the avionics ready to start the engine and have all the monitoring going. There isnt a huge length of the steel pipe on the pax side its only about 300 long and the pilot side is about 450 long. Now the radiator core is fully exposed and also the angle in the airstream is much flatter...it still is angled though so its a suck it and see thing I suppose. I am not expecting anything too dramatic

Hi Kevin. Yes I will let people know when they are available ..I made an initial 9 production samples and they went in a day basically once I said I had them. This was to finalize the laser cutting specs to make sure they were close enough. I have ordered enough to do 50 kits just to see how they go. Hopefully will have them in two weeks..CNC places are like everyone here...way behind 😞 . I know its been a really long time in coming but just too many things to do here and life gets in the way a lot lately. Also had to make some mods but I am pretty happy now with how it is Mark

Still need to put a clamp on the radiator end...I am waiting for more of the 12mm wide clamps

Another thing about the hose...I used the 25 to 40mm clamps to grip the rubber/silicone hose to the tube..but make sure you get the 12mm wide clamps not the 9mm wide clamps..and the SS tube doesnt crush at all the clamps tighten down nicely and will make a perfect solid seal

I used the std Sav radiator bracket which is just 2 smallish bent brackets but because my radiator is more facing forward I have 2 straps coming back to the bottom noseleg plate to achor the bottom of the radiator...I will take a pic later

Hi Marty Pacific HoseFlex..... they are in the Gold Coast and Victoria and Perth..I believe they actually manufacture it. You want the annular hose and no outside sleeve Download the chart and just be away the size is the ID. so the OD is much larger. The water pipe I used is the 20mm and the SS0-A. tube https://hoseflex.com/product/metallic-hose-annular/

I thought that ICP only supplies fuel and oil pipe from what I had seen. I didnt realise that they did the water as well. As I said before I wasnt keen on how thin the pipes I saw were. I am much happier with this locally sourced stuff though. To the point where I think I may use it all the time...it is a little heavier of course but I feel more comfortable using it
