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…

Better image here

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

Gliders have a much higher risk of a mid-air because there can be many gliders in the same thermal. They use Flarms which are gps/computer radio tx and rx. They cost less than $1000 each.

Does anybody know the reason why they have been rejected by CASA? My personal opinion has been that flarms are just too cheap to be liked by bureaucrats.

Not that I have ever been near a mid-air myself, the sky is really big compared to our planes. Flarms sure do alert you to all sorts of things you never noticed before, so I suppose they are a good idea. 

In two mid-air collisions I know the details  of, they would have prevented one but not the other. ( the "other" was a gaggle of gliders which had left a thermal. they flew into what was probably just a hint of lift, it lifted the RH wing of one glider and the LH wing of the other, and they turned towards each other...  bang! )

5 k range Bruce, not far enough when they require a 10nm call to inform others of your intentions 

Ken

Some feel that 760 implementation is taking too long, but for me and my Colt, I have got my rego number from RAOz so it is moving along.

I am just about to start the fabric, so I’m not to worried about the speed of 760 development.

 I have spoken to the managers at RAOz and I am just waiting for the prefix to my rego number. This should be 34 for certified aircraft. This has yet to be approved by CASA as part of the operating/tech manuals that will include some other requirements that I don’t know of I’m guessing.

it’s all happening so all good.

I think it’s time

If you get a chance can you ask your mate how much lift these things will deliver to ? ie. will they pump directly upwards say, 1m ….and how much slower is the delivery at that height ?

He is away for Christmas but we lifted the fuel about 1.3m from the ground to a fuel cap at the top of the boot cowl on a Mini Cab

This (AA) battery powered unit from Easyflo works well for me.

A mate uses this model and it works very well. I will get one for my Colt when it is finished 

Ken

We run glider training as well at Gawler.
All should be aware that gliders may be flying contrary to normal circuit direction. Not unusual to turn left on take off in a powered plane then to watch the glider turn right after launch. Then the tug will be Released at 2500ft then it will rapidly descend to 500 feet and land on any runway they want, but the runway is usually one that permits a rapid hook up of the next glider. An aircraft carrier has nothing on our operation.

RFguy, 

how would a sonex turbo go? They work at the rpm you need and not too much boost to normalise for the MAP you need.

Here's the big new Jab in the big new hangar. I like the engine, but it sure is an orphan these days. If anything, it runs too cool and I can't figure out why.

Bruce, I see that you still own the SK.
