some mug holding my plane

thanks guys,

this is a 1 off , I could supply cores & fuse if my arm was twisted

The hinge is kevlar in the lay up , from the outside its 3/4 vale,2oz tight weave glass kevlar hinge 6 oz carbon, 4oz glass & 2oz tight weave glass

the glass is cut out with a triangle file down to the kevlar, the top surface is cut through 3mm in front of the hinge line with a dremal diamond cutting blade by hand along a straight edge, then the top edge is sanded at a slight angle so it goes under the top skin , lots of work !!

still getting the rest of the pics together & a video when I have time

Well after running around this morning doing domestics, I had a chance to cut out some checker s for the left tip, I down loaded a vector file & just printed it out on A4 paper, then cut out the wing tip shape & laid it on the flag ... cut that out to shape, then used a light spray of 3M 77 spray glue to hold the flag in place while I cut the black squares.

Then I used some sticky backing tape we use for our stickers to hold it all together
I used clear book covering film as my stencil, but next time & if you are thinking of doing the same use a coloured one as itís easier to see when placing it down on the wing to line it up though the backing paper.

The covering film is a lot stickier than the backing paper & once placed, removed the backing & smoothed out any bubbles or wrinkles & masked the tip up as needed, I didnít do the whole wing I just covered it with an old sheet but should have run a piece of tape over the end as I did get some over spray on the wing under the sheet

I cheated a bit with this as I used a spray can of gloss black acrylic paint on it , after spraying it was it left to dry for 40 min or so then just very carefully removed the sticky squares & voila a check flag !! it did need a couple of touch ups & ill put some shading on it to make it look like its flying with an air brush

I then taped up the bottoms of the wings & used the fine line tape at the LE to get the straight line again, then just painted both wing tops & the fuse with 4 coats of Bright Orange acrylic, its not as orange as I had hoped but itís bright!!! As you will see in the pics

By for now

More painting today, just masked up the bottoms of the wings, will be laying down gloss black

Iím just dividing the bottom in ľ chequer as Sean had this on a wing last year at Manila, I liked the look & it was easy to see ----I need all the help I can get with this as it wonít present a big profile in the air

I have the corner over a servo hole as its going to have carbon covers on the servos later & the LE has the tape running along the very front of the wing
After some measurements & marking with tape I laid down some fine line tape then masking tape & news paper to cover the whole wing ready for spraying this was a bad move as when removing the paper later it had left ink on the white paint Ėgrrr! , it will clean off when I buff it out

I started to spray & had some trouble with the hvlp gun (cheap of EBay) & I found that there was a blockage in one of the fan holes & the gun was pulsing ,after re-cleaning it all was fine

I laid the black down with 2 very light coats just a dusting then followed by 2 full wet coats with about 3 or so mins between each coat
The paint was left for about 1 hour before removing the masking ,it has come out good with some gloss, ,Ill be polishing it up later after the top sides are painted & putting a coat of clear on it

Thatís it for now

the fuse is done now, ground down the wing root to the correct shape & used micro spheres & epoxy to get the new root foil shape , them some filling & sanding to fair it in

the fuse is now in spray primer & spot filled then I have just put 2 coats of white acrylic paint that will get wet sanded back for the final paint (Bright Orange), I was going to paint it in candy orange with a gold base coat but have decided just to use the acrylic paint

A couple more pics, setting up the wing rods in the fuse ,8mm carbon rod & ill have some steel ones as well, the ballast tubes will take lead slugs or a chrome-molly tube full length for DS
The fuse will need the wing root changing as the foil is different on the new ones but that can wait till I bag the wings

After 2 1/2 hrs it was becoming apparent that the fuel use was very low even with the trailer, we were travelling at the speed limit for this road 100kph & the engine was performing well & I was starting to get used to the shifter.

We stopped for late lunch & coffee at the golden arches in Muswellbrook, back on the road next stop Manilla!, we were eating up the kms at about 90km average & it was time to turn the lights on ,its fitted with Zenon low beams with washers & halogen high beams which give a board range & spread not wanting for more light even on the country roads, the interior lighting is very good with the blue dash lighting not giving any glare at all & the radio reception is adequate, the in dash 6 stack CD was now blasting out some tunes from the 10 speakers around the car, it was the 70ís/80ís much to the disgust of the 16 year olds in the back!!!, It's also fitted with an AUX in for you IPod for the young set, with the ambient temp dropping & the night air there is a defiant power increase, now we where travelling along above the speed limit & overtaking was very easy, the handling was very good with the trailer on the back even at speed. I had to keep looking to remind myself I was towing!!!

We had arrived at the pub in Manilla where we were staying for the next 4 days for the Slope fest after 5 Ĺ hrs on the road & about 500kms, I stepped from the car with a grin on my face & not even a stiff back or a...Continue Reading

OK you have to remember that this car is brand new & we have it loaded up & the trailer!!!

I have just remembered I have only driven the car with the trailer on it, Its just a shot drive to the Putty rd from Glennís place then the trip can start in earnest, the clutch is typically light, smooth & take up is close to the floor, the car only comes in a 6 speed manual & ill go into that a bit later
On moving away in 1st you need just a touch of revs to move off & the torque is there form as little as 1300rpm & the change to 2nd at 2500 is stiff but positive, getting up to speed is very easy with max torque at around 2800/3000 rpm the red line is at 4500 but you donít need to go there!
Now on the Putty rd its time to wind it up to travailing speeds soon you find out how much torque there is in these new 4th gen euro comply ant type diesels, its fitted with a self regenerating particulate filter, cat converter & a large top mount intercooler with bonnet scoop, over all at speed the car has very little wind noise & is riding the bumpy rd with out much fuss, the steering is direct & gives a good amount of road feel , its fitted with 17íí Yokohama soft roader type 4x4 tyres & there are 5 as it has a full size spare in the boot area under all our gear, I set them at the higher pressure setting on the tyre placard (260f kpa/280r kpa)for the trip
Now travelling at 100kph indicated in 5th gear you are at wait for it 2000 rpm & it will...Continue Reading

We picked up the new Subaru Forester (Diesel) on the Tuesday before going to Manilla & I was undecided to take it or not , it only had 120km on it Wednesday morning

Any way I started packing it up with all the gear & the boot space is quite large ,I fitted in our small fridge ,radio bag ,pillows ( must have own pillow in hotel) & 3 cloth bags ,esky bag with food & jackets plus all the rest of the SH##T you take away for a week

The trailer does double duty for us as we normally take it to dog shows with 4/5 cocker spaniels & an easy shade in the trailer, this time its full of planes & kits for the fest,we dropped in at Glenn's place to load up the rest of the gear & pick up his son Luke

The two boys in the back seats had plenty of leg room & with the adjustable seat backs could get comfortable, the center storage/arm rest got a work out with Ipods /phones & there are 2 cup holders as well

In the front the driver seat is electric in all directions while the passenger is mechanical,Anna my wife will use the car the most so is not to fussed about that,the seating is firm & well supported in the right places, the dash lay out is very Subaru without all of the bells & whistles of some Koren manufactures (we did look at them as well but decided on the Sub as we have an older Outback)

This is a turbo boxer diesel , so this would be a good test for it,I drive a lot of different cars with my work both petrol & diesel so I'm very familiar with their workings & performance plus nearly 40 years in the auto industry & the last 22 with BMW, the direct high pressure injection with pizo injectors starts & runs form cold with some typical noise but this soon becomes quite & the engine noise in the cab is just a low rumble

Will ad more later

this will be finished for Manilla next year but thats what I said last year

Have done some more on the wings of the Avalanche today ,added balsa in the ribs where they will be cut for the Elevons & at the root & tip as well.

The spruce LE has been added & sanded to shape using the ribs as a guide

The rounded tips have been done with epoxy putty ,the foam was cut off & 5 minute epoxy was wiped on then the putty was formed when dry, I have found the putty does not stick to the foam well ,so the 5 min epoxy gives it something to stick to ,then sanded to shape.
