Did just install mine so.

Drilled later when assembled on wing with 18 +-1mm lower from outer aileron

I did buy the Canopy cover, maybe should make it a rule to always have it on when refueling...

Not so dramatic with petrol but was immediate cracking and failure of the part, not so much crazing.

Yes, tried down to about 10-15 deg, same result with failure at the point of most stress.

 

This morning I cut some bits of polycarb and .016" ali and riveted them together in various configurations and poured a small amount of thinners on each.

 

Firstly I made a multi rivet test, with two rivets through 1/8" holes- no extra clearance,[ATTACH]38877[/ATTACH]

 

then two rivets with 1/8" hole in the ali and 5/32" clearance hole in the polycarb,[ATTACH]38878[/ATTACH]

 

then two rivets with the clearance plus a nylon washer under the rivet head,[ATTACH]38879[/ATTACH]

 

and one unriveted hole for control, no photo of that one but it had no cracking. So you can see all of the the rivetted holes had some cracking but the clearance holes were the smallest and least cracked, so I did some more tests with single rivet pieces with a clearance hole and destressing them with the heat gun for vaious times. Heat gun was on high setting, 150-200mm from piece, waving across piece not concentrated blast, and I allowed the part to cool to room temp befor applying the thinners.

 

first, heating for 1 minute[ATTACH]38880[/ATTACH] and as you see not one crack. Encouraged by the result I tried several more individual tests with varying heating times and found I could destress the rivet penetration with as little as 15 sec waving the heat gun over the part. Lowest time I did was 7 sec and the thinners produced 2 small 1 to 2mm cracks.

 

So from these test I reckon next time i rivet in a polycarb window i will drill clearance holes and spend a small time destressing with the heat gun.

 

Cheers

Cabin heating hoses installed.

All the panels around the empennage installed, damn it was tight.

And control rods connected.

And some other small shit...

Something doesn't add up here. The factory planes come out with the roof panel partially painted, and I think Dennis painted some of his roof panel too. I am not aware of cracking when this is done.

Had a quick look but can't find it. Take it this is a tool for adjusting something ??? Much later in the build.Lyndon

I got all tank fittings pre assembled from icp with holes for tanks and sight gauge.

Australia don't want this?

Just a weird thing i noticed today when sun was shining on the black surface, i got a big dent in the black leading edge of the wings, do they react on heat and expand ????

Very cold and some instant sun....

Weather is still ok but cold as hell..

Small work tinkering.

Riveting roof.

Gas return tube.

Pitot & Angle of attack tubing.

Petrol hose from wings

Cleaning up the bridles.

And Ailerons.

Just assembly of stuff to get it airborn

It is getting closer Dennis....how long before the first flight do you think?

WE had -8C freezing degrees today so i think not before spring , ill spend the winter with paperwork and video games instead.

I successfully upgraded the power of my aircraft with one dogpower!

Installed the cabin heating.

And the oil thermostat.

And some more... Takes long time.

The small tank inspection panels are an icp thing, wrecked one tank panel and got one new with holes in, had to have symmetry, copied to other wing.

So i took everything i had and allot extra and threw it on the airplane to see the weight of it, 295kg, but the cockpit mats was still in its cutout leftovers.

Still need oil and water and my limit is 297,5kg so when i sorted the mats i really think i can do it.

Inspections panels for wing tanks.

Roof painted.

Stab/eleva wing tips.

its allot of small parts to assemble.....

Heres mine,,, its wings... you attached them when wings sit on fuselage.

First thought is leading edge Wings against front window, thats only place i can position them, looks a little bit diff than mine but you have a newer model.

This list made my sorting SO much easier, i bought 20 boxes and sorted everything by chapter.

I like this in principle because carbon monoxide poisoning is almost non-existent due to the two layers between exhaust gasses and cabin gasses. But, I am still left wondering if there is enough heat transfer in 300-400 mm of pipe which only overlaps by half the circumference?

The fan is built in, can't see it on photo.

It is supposed to make 3,5kw of heat.

I have water system like this that I have not installed yet, got this foto from a Norwegian Savannah.

Is popular.

So take your time and read other build threads in this forum, they have allot of photos and will probably answer most of your questions.

I installed a oil thermostat, engine manuf said my oil cooling was to good, bought a ordinary Mocal OT/1, saw the same on a Rotax and it was not the expensive on ebay, not yet completed since i wanted some firesleeve over the oil hose.

I wanted to remove the overspray so i roughed up the old paint and added new paint, that reacted with the old paint and made a raisin surface, it was easy to remove the paint down to the primer, i added new primer and new paint, lesson learned.

And a Great Sunday Resulted in the wings getting mounted!

Gathered some friends and had a good time.

I just attached one so i could paint the stab and elevator seperatly, when painting was done i attached the plate and elevator.
