Skippy, please read your 7 point discussion plan on your first post initiating this thread.  I feel that my previous post fits your criteria for discussion.  Please indicate where I was rude.

Read an article in Kitplanes Magazine a few years ago comparing speeds with arrival times.  They used (from my memory) a 75/100/120 kt aircraft and flew the “normal “ hamburger run of one hour to a neighbouring strip.  
 

While there is a difference in transit times the advantage could be lost in both departing and arrival circuits.  There bottom line was that if you are flying for about an hour…..transit speed differences mattered little. It really only meant anything meaningful if you are approaching 2 hrs.

I put this to an informal test and flew out of an air show with traffic management so all ran smoothly.  Some had to turn right at 1000agl while the following had to turn left at 1000agl and so on.  A Gazelle departed only 5 minutes before me and with a 75kt cruise speed (had the very first Bolly prop approval).  He departed one direction and I the other.  He stayed low and I climbed 1000 ft higher than him @ at 100kts.

I handed a couple of minutes after him after a distance of 100 miles!

He flew low, not wasting time climbing and descending and probably picked up a more favourable wind, enjoying the scenery.

So all this “mine is bigger/faster than yours” is well…………pointless?

 I have gone the other way and will be lucky to cruise at 90kts, but have installed a skylight and clear door. I fly at 1500agl most of the time giving me the sensation of speed and I am looking to enjoy the close up views.

Has anyone tried this style of reinforced baseball cap? My Colt now has a skylight with plenty of opportunity to extract some claret from the old melon.  I don’t think I could get away with a dedicated helmet as the style of aircraft would initiate “Wan@er” calls but I should be able to get away with a toughened bb cap.

Come and see me.

Where are you based?

Check wether you have Randolph, poly fibre, etc. then follow the makers instructions as to the repair method.
I have just about completed a Randolph system and it is very easy. Note— you can not mix systems. It should be in the log book. Or you can look inside the fuse and look at the base colour, it could be green or red, the most common colours. This will point you in the right direction.

If my memory serves me well the original Jab was called an LSA years before the new up to 600 LSA was even thought of. I almost bought one. So Jabiru had the original “LSA”. It also had a couple of other designators as well.

I ran my Gen1 at 2800 and it never got hot. Take off and climb to1500 ft was 3000@90kts.

Earth X do STCs for many certified aircraft

But it’s a colt ❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️, will it be losing the front wheely thingy ?

I can’t dance so it stays a milk stool

Just for giggles….my Gen1 SP500 uses 11.7lt/hr.   100 true @ 2800rpm with 44” pitch wooden prop. 
 

Just sold it this week after 18 years. Why you may ask? So I can pay for the rebuild of my Lycoming:  And can now look forward to 24lt @ 90 kts. Hmmmm !

Our club has 4 Gen4 jabs and one Gen3.  The Gen4 run best on mogas and run cool compared to other generations.  Highly recommended.  Stay air cooled and bank the extra useful load and put the money saved to more fuel so you can get out more.  I have worked on all generation engines and the best are Gen 4, particularly in a training environment with up to 8 T/O and landings in an hour, though I have a soft spot for the last version of the Gen1.

best not to over think these things.

Years ago when I did my solo nav, I was going to go to Aldinga, so phoned them in the morning and they said that it was not recommended that day as there was a strong easterly off the adjacent hills, and would be best if I had a few more hours under my belt as when an easterly is blowing it is not the best place to be.  I have flown into there since and you can see that it is sandwiched between the sea and the hills.  Great place for a coffe…

I had a bet each way and have installed a skylight in the Colt.

I did the tubing on my Colt using Linseed oil.  It is an approved method.

My Colt already has its number, just waiting for the prefix (probably 34 at this stage)

Mick visited Gawler on Saturday and was part way through an Australia wide trip speaking to pilots and answering questions. I had to leave early but he said:

230 and 430 will be factory manufactured at 760kg

170 will continue and 230 @ 600 as well

Gen 3 parts will be manufactured for all that have that engine can relax

working on a Gen 5 engine BUT it MAY be electric

will include analog instruments for those that want them to keep everything simple for people like me

he is a pilot and so is his daughter 

all the staff are remaining

he is the MD at a major military supplier but can not divulge any more details about the products.

 I Had to leave then but Jabiru 7252 then arrived so may be able to shed some light on any further detail.

Sounds all good to me

Those strut bolts in the first picture don’t look like AN bolts.  If not they are not airworthy. Don’t use grease or Loctite on any nut or bold particularly nylon nuts.

Could you fit a sheet of thin Lexan under the framework?  I’d rather hit my head on that than a metal frame.

The STC doesn’t allow any deviation from the plans.  The “joys” of certified aircraft!

I have put a skylight in my Colt and it sure has a lot of hardware just above my head. I guess I will know soon after the first turbulent flight.

There are a couple of “STOL” Jabs around, though 19 built.
The SP 470/500 fuse with the 450kg UL wings, powered by the 3300.  

We had one on our airfield for years. With the 35kt stall it was ok in the relatively short field landing phase and with the 3300 took off like a rocket.

”19” is a great category

Wooden prop should use Belleville washers, just like the jab wooden prop. 72 inch pounds of torque

I have yet to purchase mine and claim the rebate. If it’s anything like transferring a VH registered plane to a new owner, me, there was 8 pages of instructions so I could fill out a 2 page document. Unbelievable.

I was listening to a psychologist a while back who said that nature has developed and reinforced the fear of heights for our species survival .  If we stand at the edge of a cliff, we need to protect ourselves so adrenaline kicks in, the ‘Fright’ part, to stop us there before taking action or to back away.  Same with being at the top of the tree.  
Apparently we are physically connected to the ground (safety) through our senses - we see the potential problem, but we feel the solution because we still keep our feet on the ground/tree keeping us based. This has been passed through the generations for ever.

BUT , flying (not falling) has not been implanted in our DNA as unsafe, as it is not a naturally occurring situation.  Children won’t be afraid of it as it only becomes a learned fear, through their own experience or relayed information from others.

It was an interesting article
