Tubbso burst through the tent flap, and yelled "April fools! Show us yer ASIC!". Ben felled him with a right cross......in full swing since Rat had earlier spiked the punch. "Waddaya reckon Ben?" asked Madge Jayco, "the lightwing flicks hard to the left, can we only do left rolls?" Ben tried to snort derisively, but snotted instead. "Pitts pilots don't know their left from their right anyway!" he asserted, then blushed inexplicably. Suddenly.... -
Great Wall looked up from Hy's recumbent body, and screamed, "his warranty is void, you PLICK!"; but Maggot didn't hear, as he staggered back in shock and replied reflexively, "I may have left it in my flight bag...". Ratso moved fowards ominously, being careful to keep his arse in the shade....the tent next to where they were judging "best board member outfit" behind "the hop skip and jump competition" which was in full swing since.........Ben had let off a can of "start ya bastard" in the men's room. At that point, the Rat dropped one paw on Maggot's shoulder and rasped, "let's see your ASIC, buddy!". -

The front of the lowest-drag (incomressible flow) shape known - the teardrop - is a hemisphere; and the hemispherical nose on the hubs of Hamilton Standard props was actually very effective at keeping up the cooling air velocity. The Albatross solution put most of the hemisphere in the fuselage shape, but there's no reason you can't put more of it in front of the prop. It'll look a tad unconventional, but should add measurably to the prop thrust.Hi,I see what you mean. Looks a but bulky, but I can see how this would be effective. I'll have to start drawing to see what I can come up with...Duncan

..."sexy" said Don Quixote, who was still looking a little stunned from the slap given him by Major Maggott. "Rook!" cried Hy Undai, "pansy cockroaches!". With a noise like an O-360 hydraulic locking, Hy fell to the ground. Over him stood the red-faced, sweaty figure of Maggot; and over him loomed the cadaverous red-eyed visage of the rat returned. Don looked around in shock, while Madge........ Start-ya-Bastard."Don't start that with me" said his Madgesty "As I am a Board Member, I am from f'n Q and I am .......

A larger spinner will generally allow a broader speed range from a fixed pitch prop; and, provided it's not too sharp, reduces the overall fuselage drag quite a bit. The old Albatros biplanes (WW1) has pretty effective spinners, but since the jet age came along, people make spinners too sharp...Hi,Gosh, I turn my back at return to see you hard at it. Good on you... I have to just sit back and gaze in wonder at all this. Fascinating, but completely beyond me.You mentioned spinner size once or twice. I favour a large spinner (currently looking at 14.5") but this is not set in stone. It just looks nice.
Some design targets:
Stall 43kts
Cruise 135kts
My engine produces 50hp @ 3600rpm, and is fitted with a 1.6:1 PSRU.
I trust these specs line up OK with your prop tinkering?
Regards,
Duncan

Ben Tley, who was standing in the shadow of a hangar, shuddering. Foam dribbled from his mouth, his face was slightly grey, and his fingers were twitching. "Undead!" screamed Madge. Ben smiled, and brought up one hand holding a can of........ put on a blues gersey, tell cockroach stories and quote Jo Bjelke jokes."Erky perky" said Madge Jayco, who made the sign of an anti-vampire cross with his fingers and backed away, until he reversed into .....

Yup. I'm there... Daryl Greenamayer's F-104 was a homebuilt, wasn't it?Sounds reasonable......as long as you built it yourself. -
Statistics is not fun?This thread is now way off topic.I put it to the forum: the issue of regulation according to safety of third parties would be reasonable, is applied fairly. Now, on a D?L medical standard, I have a license that will allow me to drive a 20,000 litre (non-articulated in my case) petrol tanker through a major city. Potential energy in a crash/burn? Lots and lots. Therefore, RAAus certificate holders should not be allowed to fly anything with a total kinetic energy greater than... a P-51?

No, it would not be a viola...I reckon an old 55 airframe transferred to 19 rego would make a great little machine... chuck the anchor weight in the nose out... put a Rotax (or heaven forbid a Hirth 110hp 2 stroke!)... stick a little wheel on the tail... enlarge the rudder... turbulators on the elevator... and voila!- 1

Bennet, of Pathfinders fame, was "lent" a P-51 to orchestrate target marking on a night bombing raid. His first flight of a single-engined aeroplane more powerful than the Miles Master, was in a P-51, at night, over Germany, controlling a squadron of pathfinders whilst flying at low altitude through the flak over the target. He succeeded. He was not trained on an "easy" or "well-behaved" trainer.BIG subject...... I wouldn't like the job of getting an ab-initio solo on a P-51. You'd lose a lot of planes, students and instructors, but you would get some through ( at a cost)A good instructor has the job of steering the student through the course dictated by the system, so must cover the plane used and it's characteristics, whatever ot is. A training aircraft should be tough ( most aren't, today) behave like a real aeroplane and be serviceable and cheap to purchase and repair.I don't believe anLSA 55 is "twitchy". It is a bit quick and has limited control authority at lower speeds. It doesn't lend itself to ham fisted control and you don't put weight on the nosewheel. This is a little bit in conflict with the need to NOT get slow on the approach, hence some fairly precise flying is required at times. This also applies to a lot of other aircraft so the skill is not wasted .The throttle position is "something else". Thankfully it's not done like that any more. Nev
Now, I agree that a novice to flying should be eased in to the addiction; but to what degree a pilot's certificate is a professional qualification - as a Heavy Rigid d/l is - and to what degree it's a ticket to a pastime, is not so easy to define. One can't earn much money as an ultralight pilot; but the complexity of the task, and - here's the can of worms - the potential risk to third parties - makes it more similar to an HR licence than an ordinary D/L.
I suggest that all newly-elected politicians be strapped into a single-seat P-51 and sent off - those that return, may govern until the next election...

Yup, hop out of an LSA-55 into a T-300 with the large wheel option... they land exactly the same... NOT!the little LSA Jabiru will teach you to really fly. the aircraft won't help you at all. and if you can master the LSA, then you can easily fly anything.A lot of people who learned in Drifters had very high blood pressures when moving to a T-300 or T-500, because the Drifter's artificially enhanced stability tends to mask its adverse yaw, and the low ground angle makes aerodynamic bounce almost impossible. Does this make the Drifter a bad low-energy trainer? No. Do its ability to bounce, raw adverse yaw, and non-blown fin make the T-300/500 bad trainers? No. Provided the instructors managed to gauge the student's actual abilities and confidence levels accurately (not so easy, it seems!), either can be used to train a safe pilot; but the Drifter cannot be used to train a novice how to fly a Thruster; because they are not the same.
After doing my U/L training in a T-500, I found the LSA-55 a pussycat - and it had brakes!

Statistical analysis of information can reveal more than is at first evident to the unassisted optic. Some of this revealed data may be true. If the data revealed by a statistical analysis can be verified, then it is valuable. Mathematicians are poor users of words, so many statistical terms are misleading. A great deal of the early use of statistics was in improving the average quality of Guiness Stout, which is a noble occupation for any mathematician. (Maybe the only worthwhile thing they've ever done? No, no, I'm sure they've done something else useful, or why would the species survive?)There is information in all statistics but it is the deliberately biased selection that makes the outcome suss.

...as one would. . Sight of Phil's avatar brought to my attention this fact: NO AN-2 has ever suffered an in-flight cabin depressurisation, even with a hull breach - and I can find no record of a cockpit oxygen fire, though perhaps Aeroflot could better inform us. Anyway, the vanishing Boeing surely informs us all to fly AN-2 - or don't go commercial!I'd agree broadly with that Merv, and since it's now 23rd of April, the link regarding the identical aircraft on the shop floor at Boeing, just 4 serial numbers away from the MH370 airframe which had a pressurised Oxygen cockpit fire whilst the aeroplane was still on the ground,. . . resulting in the cockpit and all flight control equipment being burnt beyond recognition, and the hull being breached ( First Officer's side ) to the outside,. . . . . this would seem also to be a good parallel candidate, as, if this had happened in the air,. . . .well. . . . .let's guess what might have happened . . . . have you ever tried to put out an Unleaded petrol fire with a hand held extinguisher ??. . . no ?,. . .well, try it with a pressurised pure oxygen fire. . . .mmmm . . . Forget it. . .. there was a Boeing modification issued at the time to preclude similar fires ( caused when the First Officer's emergency oxygen mask illuminator bulb overheated. . . .) , but did all of the current operators carry it out ?? the ground accident actually happened to an Egyptair flight.Tenuous ? ? ? ? ? I dunno,. . . .It's the best theory I've heard yet,. . .as the crew would have switched off everything electrical, to isolate the fire, and turned the aircraft towards the nearest large runway . . . . . . which is what ( Allegedly ) happened . . .according to the story. . . . . READ THE LINK. . . . . . it's on this thread somewhere ( I thunk )Interesting anyway.
I'm probably over optimistic, but I still CAN'T bring myself to believe that the crew killed that aeroplane on purpose. . . . .
The latest conspiracy theory over here in the UK is that the recent Korean ferry disaster was caused deliberately to divert media atttention from our Malaysian plane mystery. . . . . . ( ! )

...dorsal region, though he assures me the pain is fading." At this point, the earth began to vibrate, and a dull growl overlain with a shrill whining noise like Bernie Ecclestone on heat began to echo off the hangars. Turbo shook his head and shoved at Ratso, which resulted in............. picked nits from Turbo's thinning & dandruff encrusted hairline.

Normal distribution - I would argue that (1) a Dunnydore is the median mass vehicle on the road - or near as - and (2) a single-occupant Dunnydore is a reasonable representative of an average commuting vehicle in Australia. It follows that 200km on a GPz-900R is equivalent safety, of benefit to society via reduced emissions, and has a smaller road footprint for half the amount of time! S**t, us motorcyclists ought to get medals!Aaah, but the numbers change again, if you use a B double or road train as a comparison.- 1
