The six is particularly smooth. I flew the 230 to Bundi for a scheduled service. The new motors use practically no oil in 25 hrs. The new cast crankcase has the fuel pump set back closer to the flywheel so that it can be removed without first removing number 5 cyl. Cooling fins on the new cylinders are much larger.Looks great. They should sell like the proverbial, particularly the six.- 1

That is the correct photo. They are a two piece housing and they still require through bolts, albeit longer bolts.Then perhaps I have the wrong browser. What mine shows ( http://www.jabiru.net.au/images/documents/2200_flyer.pdf ) has an obvious join line down the centre and has been cnc machined. That would require through-bolts to pull it together.Could you please point me at the url for the new version?We have a brand new J170 and a brand new J230 at YCAB. The new cast crank case is very similar to the old CBC machined ones. The mating surfaces have been machined. They are definitely not one piece units.

If you have a close look at the four cylinder engine, you will notice that the crankcase IS a casting, whereas the six is not.Well, I am now confused! (doesn't take a lot, I admit, but I am at least a step ahead of the piece of paper with 'Other Side' written on both sides..)On the Jab. website, the engine piccies show the new barrels and heads mounted on 'Gen 3' machined crankcases.So: is what Jabiru currently show, now been surpassed by another version?

This particular one is a two seater.F2B or similar?The SE5 was a single seater. -

Crikey, you need to do this sort of revision under the supervision of an instructor. In the training area to start with. Practise climbing and descending at the correct speeds and use the trim. Practise descending at 65kts and get it right before even thinking of going back to the circuit. Definetly seek the assistance of an instructor.

It appears to have been deleted out of the latest Aip, yet there is still a question on separation in the latest RAAus air legislation test.

Clearance from controlled and active restricted airspace depend on what altitude you intend to fly at. Below 2001 ft: 1nm, 2001 to 5000ft: 2nm, and 5001 to 10,000 ft: 4 nm. Hope this helps!Apologies - I meant Restricted.- 1

This is a relatively new build.Some hotted up "T"s run the "A" crank as it's got bigger diameter journals, and machine the block to suit. I'm not sure what was originally fitted. to the Piet. It depends on the date of build. The A wasn't made until 1928. There was plenty of variations of the T as used for competition. Even OHV conversion as was also available as a modification for the Henderson Motorcycle engine of four in line specially for aircraft. but AIR cooled and smaller displacement. I'm not suggesting the OHV was used for the Piet ever but there's other ways of getting more power. Till Tetraethyl lead was available, 4;1 was about all the compression the fuel could stand without destructive detonation happening. Ricardo and a few others were developing squish combustion chambers for SV engines. Harley Davidson paid for Patented designs by Ricardo at about that time, where and when they were incorporated in their engines Nev -
This particular Foxbat had small cracks in the windscreen when the owners went to pick it up brand new, but you already know this. The owner had to wait months for a replacement under warranty which never showed up. You are also aware of this.First, I have great empathy with the pilots and passengers who experience door, canopy and windscreen failures - I have experienced a bubble canopy coming open in flight myself; it was not a pleasant experience. In comparison, losing a piece of windshield must have been extremely frightening. Thankfully, such experiences are extremely rare.A few facts about the above references to the Foxbat may be helpful.1. There have been no reported cases of 'vapour lock' in the 1000+ worldwide fleet of Foxbats - except for one aircraft in SE Queensland. This is because the wing tanks provide a continual fuel pressure of at least 0.5 bar to the pump, precluding the possibility of vapour lock. Almost certainly the cause for the reported engine misfiring in SE Queensland was carburettor ice: long descent from altitude, high humidity, no engine warming, misfire disappears as the aircraft descends into and remains in warmer air.
2. Apart from one documented birdstrike in SE Queensland, there have been two reported windscreen failures in Foxbats worldwide - one in Kazakhstan and one in SE Queensland. That's a rate of 0.002%. The Foxbat windshield is 2mm polycarbonate sheet, UV-proofed and scratch resistant, manufactured by Veralite in Belgium; it is the same as other polycarbonate sheet manufactured under trade names like Lexan, The product is used because it has excellent weather resistance and remains flexible even after prolonged UV exposure. Both incident aircraft were known to have had substantial cracks in the windscreens before the incidents, particularly along the front edge by the firewall. Cracks can be induced for a variety of reasons - they are most common in flying school aircraft, which have very high landing numbers per hours flown and more than their fair share of heavy landings.
The Foxbat maintenance manual clearly covers what to do if cracks appear in the windscreen, including replacement in some circumstances. Personally, if I found a windscreen crack in any aircraft longer than an inch/25mm or multiple small cracks, I'd replace the screen rather than stop drill the cracks.

From Casa's perspective, mission accomplished.What a shame for all owners and the industry. CASA really needs to shoulder some significant blame here...- 3

It takes two to tango!Probably comes down to only one, a guy who is a bit "rigid" in his ways.- 1

Wasn't too bumpy but I sure pulled up quickly once I touched down. My main worry was getting off again. Used up a lot of runway!Thanks! Still bumpy? -
I was there last week. The grass was long, They definitely need to mow it!Haven't been there for awhile and is planning to go this weekend. What was the strip like? -
Really good movie Planey. Agree with your sentiments.

Good day and welcome, Mike.

The seatbelt anchor points are in the right place too. Not so for some aircraft.Very good photo of the damage here: Ultralight pilot’s miracle escape near ManillaA pretty good advertisement for very tight seatbelt and tough occupant protection.- 1

Well if you want it done properly, do it yourself!

The A32 is a Vixxen, not a Foxbat.

Beautiful aeroplane and great photo!

Made by the Rootes group and they have a Roots blower!Yes, the muffler is not hooked up. Two strokes unmuffled are not nice to be near. Nev
