Check out the callsign - JINX - maybe he was...

When I was working, we had very expensive software that could model heat flow in and around various substances. It was really impressive to watch and when we validated the model with real world stuff, I was impressed how close the two were.

I do not think spin training or spiral dives (did both as a PPL student) are required in LSA training. We used to do fully developed spins in the Tomahawk. Spin long enough for the instructor to point out airspeed, rate of descent, impact point etc. Thank God we don't do that anymore, I'd lose my lunch in my rompers pretty quick these days...

Go fly a Tomahawk (PA38) They were designed to have a 'nasty' stall. Pull the yoke back and keep it there and 9 out of 10 times the left wing will drop, like a rope breaking. I remember many stalls, spins and spirals in the 'Traumahawk'.

Take your Jab up high, do a 45° turn and let it stall. You'll find the Jab does not flip into a spin or turn upside down, it will actually level off if anything. Jab stalls are very benign.

You should be able to handle 45° turns without a worry at those speeds. You might need them when trying to get down between trees into a clearing during a forced landing. Go out and try some steep turns at slower speeds with plenty of height just to see how things feel.

Where did that info come from? It's wrong! When I learnt to fly the Jabs it was in a J160 and my speed on late final was around 60kts. I think you'll find 45kts clean and 40kts with full flaps. (10 minutes later....) I downloaded the POH for the J160D and it does state what you said. That's very strange, I'd be tempted to contact Jabiru.

Has anybody read the last post in its entirety?

I think it is.

I built a crystal set...

Well, you can download degrees from the internet, why not a pilot license. Go for ATPL, they look authentic enough to fool the masses.

Did you mean 'elevator' in this part of your comment? "No matter what you do to the rudder in level flight it will not cause you to turn, ...." Cause, my rudder makes me turn. In a turn, especially a steep one, pulling back on the elevator will tighten the turn, but we all know that...

Buyers are not prepared to pay a fair price and sellers ask too much!

I Google that aircraft make and get motor bikes (sigh....)

My halogen light causes no interference - why would it? The strobe doesn't either though some can. The strobe electronics fried not long after I bought my plane so I replaced with a cheap unit from Dick Smiths. (A burglar alarm unit). Cost $40 as opposed to $350. Been working great for the last 10 years.

A simple way to describe what's going on. The airflow pushes on the deflected surface (elevator/aileron etc.) and the reactionary force pushes the surface in the opposite direction of deflection. For every action there is an equal and opposite reaction. The downward pointing arrow is a vector representing the deflection force and the drag.

What about paving bricks? Is that a silly thought? Seems a hell of a lot of money to concrete a hangar ($18K). I know of one or two hangars with no floor, just dirt.

100mm would seem thick enough to me, but I'm not a concreter's ass...

When the shed at mums was concreted the idiots didn't put down any plastic sheet so we had this problem of salty stuff coming up through the floor. Ended up coating the floor with some goo using a broom and it did the job.

From my experience the folks who build the hangar should know what's required. If they don't then they're shonkys.

When I want GPS backup I use an old Garmin Nuvi in 'off road mode'. It displays the planned track as pink lines and my actual track is displayed as a blue line. Works a treat. And you can overlay the data on Google Earth and replay it.

I find this a bit like using calculators. Why 'do' the math if you can use a calculator? I know a few folks who cannot subtract 35 from 50 without using a calculator or pencil and paper. It's sad that technology can actually makes us dumber.

Nope. I enjoy doing it the old way, both planning the flight and flying the plan.

I thought that Jabiru engine debacle was due to corruption and abuse of power. Somebody had it in for Jabiru and was gonna make em pay. Or am I mistaken?

It's all fun until you divide by zero!
