Jabiru7252

Last years calendar shows Savannah aircraft at www.outbackaircraft.com but I get some "ftpquota" error when I go there. Any ideas?

Actually, it was a stud, not through bolt.

How Jabiru - how about fitting Rotax engines to your planes, I'm sure people would pay the extra cost.

Just some rough (back of the envelope) maths. A turn of 360° in 60 secs at a radius of 600 meters puts your speed at about 122.2kts. An object on you OUTER wingtip 2 metres away is doing 122.6kts. An object on your INNER wingtip 2 metres away is doing 121.8kts. A difference of 0.8kts. Correct me if I'm wrong. No angle of bank factored into this scientific revelation.

I would have thought the dial would be 'cramped' down around the stall speed (like most light aircraft I have flown) and a few knots would not be apparent.

You'll find the fuel bill somewhat smaller...

Hmmm, if the engine is switched off and is wind-milling and acting an air pump, carby icing could occur, or am I being blonde?

Remembering that a closed throttle doesn't need much ice to choke off the air supply where as an open throttle needs a lot more ice to cause any problems. There is a good video around that shows this in a laboratory setting but I cannot seem to find it.

Wish I was 65kg again....

When folks make certain claims can they give us an idea of what authority they have to make the claims? As an example, one can only compare CASA to the US, UK, Canada equivalents if they have had intimate dealings with all organisations. By the way, I'm sure these other countries have pilots who hate their 'CASA equivalents' to bits.

Be aware - if you use change.org you may get pestered with emails about every dammed issue on the planet, I sure did.

I use it heaps!

So, what's the problem with the Kuntzleman Electronics Dual Magnum strobe power/driver unit? The strobe electronics on my aircraft was ridiculously over complex and expensive. I replaced the electronics with a unit from a burglar alarm system. Less than a quarter the cost and works a treat. Being sealed up in the original case makes it safe for those who would like to 'make waves'.

As an example of how pathetic Facebook users can be, I missed a family event because I never knew about it. When I asked why I wasn't contacted the reply was 'If you don't want to be on Facebook, your loss". Needless to say, I would rather miss events than associate with morbidly obese fools that think they have many friends because they are on Facebook. How many of their Facebook friends would lend them a dollar in times of need?

If you want range and a solid airframe - Jabiru is just great. If you want to take off and land in short crappy strips, maybe a Savannah or Foxbat. Create a spread sheet with rows as features, columns as aircraft and do the research on the web. If you rely too much on folks here, you'll get biased opinions and in some cases lies and exaggerations. Read up on hip replacements and you'd rather spend you life in a wheel chair than have the surgery, the point being is that people post negatives about their experiences far more than the positives. By the way, Jab, being made here and of fibre is pretty quick and easy to get repaired if you put a hole in it.

I would have thought that headsets and radio/intercoms would all meet some standard so there would be no incompatibility, either electrically or physically.

According to my memory (and the ARRL handbook, 1977); An antenna that is physically short becomes capacitive so the coil adds inductance to cancel it (the capacitance) out. If you measure the length of wire in some coils it does not make up for the shortness of the antenna. It's a very complex topic and like the generation of lift by a wing, many folks have their own 'expert' opinions as to what's really going on. I would hardly see a quarter wave on the aircraft bands being too short, so any coil would have some other 'impedance matching' purpose. (sloping back at 45° is purely for looks.)

Oh Man - I forgot about that!!! Any Nazi thought police out there please forgive me!

Loading coil does not make for a 'ground independent' antenna. If your plane is metal, I'd expect the antenna to be a quarter wave mounted somewhere externally with the metal body acting as a ground. If the plane is fibre (like my Jab) then the quarter wave radiator will have a quarter wave piece going in the opposite direction, basically making a dipole. In some fibre planes, the quarter wave radiator will 'act' against a ground made of a thin foil Not sure if that would have to be connected via a wire back to the electrical ground. All the antennas should point vertically so the 'doughnut' shape radiation pattern is used to best advantage. Being an old fart, my theory is a bit vauge and possiblly out of touch. Having said that, if any Hams are reading, I hang out on 7Mhz and the callsign is VK5KKS.

Head shows signs of "pulling In" What's that? Is it something one can keep an eye on through leak down tests etc?

Come on guys.... starts in games, ends in tears.....

How much to print me a woman? She must be very feminine and petite as well as easily dominated and possessed. I'll pay cash.

The pilot of the Jab that landed in the paddock was very new, in fact this may have been his first trip away as PIC (apart from navex). Anyways, he did mention on the news he feared the door might come off and cause real damage so he elected to make a precautionary landing.

Sounds like squelch problems. Radio squelch should be adjusted so background noise is not heard. Normally adjusted when the engine is running. Don't wind on too much squelch or weaker signals will not be heard. Intercom squelch is similar but normally adjusted so your voice can be heard (and your passengers voice) but background noise cannot. Are you twiddling your knobs accordingly?

I posted, then deleted, then reposted, so now all will be confused because responses precede the posting. Kinda like fooling about with time I guess.
