Hi Guys

Well I have done a little bit more work on her. Still a few more details I want to add then she will be ready for painting next week

I have finished the IR Suppressors using 5mm strips of 0.5mm plastic

I have started worked on the light covers.

6mm balsa was roughly cut to size then shaped using an old worn emery board of my wife's. I used an old one as they are a lot less abrasive than a new one and make shaping the formers easier

Sadly I did have a minor set back with the mechanics on Monday night. I powered and tested everything it all seemed fine. when I powered up a servo failed causing the heli to roll over on ground. just one of those things I think you never know when a servo will fail. fortunately there was only cosmetic damage which will be repair soon a new servo which was really hard to find should be here tomorrow meaning I can test fly Monday and hopefully Thursday will fit the fuselage and test fly before painting.

Ok carrying on from where I left off. I gave some thought over the weekend on how to support the plastic while I heated it then dropped it over the mould. I came up with this 2 part frame held together by nuts and bolts.

I cut 1mm clear plastic squares which I clamped between the to parts of the frame heated over the heat gun for 20 to 30 secs and pulled over the mould to form the part

and once cooled cut to size

for those that want to see how its done here's a very quick demo

Watch at YouTube

Take my advise guys if you try a good pair of over gloves is a must

I next marked out the position of the lights and drilled out to 3mm which is the size of the LED's and to see the rough effect fitted the lights and powered up

Been working hard finishing making the last detail this week so I can start painting her this week or early next week.

I made the wind screen wipers and attached the lights even though I am still waiting for a scalerchelis light controller to arrive.

these where very fiddly 1mm x1mm wiper blade with 0.8mm hole drilled for metal arm which will fix the whole thing to windscreen. took several attempts for each side to get right

The anti col lights where made by shape 0.5mm plastic to fit inside the light cover then a hole drilled for the LED and covered with tin foil. once the glue dried was then glued inside the light cover

the LED where glued into the light covers with cyno and once set glued onto he fuselage. Once the glue had cured I fitted the mechanics and checked nothing was catching and lights worked

she is ready to visit my club to see if she flies

No Rich the copterX blades are very forgiving. She was on my EVA helipad when she rolled. The only damage was cosmetic on the tail rotor blades which won't take long to sort out and a job that needed doing as after 50 plus flights where showing signs of wear on the finish

What this space as my next post when they get photobucket working properly I post her in fuselage flight test

Ok guys Thursday evening I left home heading for my model club. In the boot (trunk) carefully placed in a carry bag was my baby minus blades. On arrival I left bag on the table and head off for a chat and nerve calming cup of tea. I removed her with great care from the bag and fitted the blades and very soon had an admiring group asking allsorts of question as they had on seen her as a pod and boom. This was nice and it always a pleasure to answer questions about what I was doing. But this didn't hep the pre flight nerves.

IMG_0557 by Glen Davis, on Flickr

After a second nerve calming cuppa I moved her over to join the que for flying at the power up table and do some very careful pre flight checks everything seems to be ok except there is a possible loose or bad solder on the lower nose anti col light but nothing that will stop a test flight. My turn arrived and pulled out my EVA helipad and placed her down in centre and walked to the flying position.

A deep breath flick the throttle to normal mode press timer start and slowly easy collective to 50% rotors running still not light add a little more and bit of a wobble and up we go. Guys please bare in mind as you what this I am still very much a beginner BMFA A certificate isn't to far away now

Watch at YouTube

SHE FLYs !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! as you can imagine I was chuffed to bits no real issues a little tail heavy but a look at battery positioning should cure that without adding any weight

Now I've proved her airworthiness its time to paint and make the finishing touches and think about what to do next.

I'm looking forward to hearing what you guys think of her so far any advise and constructive criticisms is always very welcome

Congrats on your maiden. It looks to have gone well, despite the Prom night jitters I have been following your build and this heli is very nicely done. I'm looking forward to seeing it in color.

The painting process has started and as I'm sure everyone knows the key to good paint job is in preparation so my first task was rub down the whole model with 400 grit wet and dry and warm soapy water. From this point onwards you must always wear rubber gloves when handling the model to prevent oils in your skin contaminating the surface and ruining your paint finish. I use surgical type gloves from tool station

After rubbing down The parts are set up on my make shift paint bench I like to have 360 degree access all round to make paint easier.

IMG_0565 by Glen Davis, on Flickr

I sprayed all the individual part with 4 light coats of Halfords grey primer.

IMG_0566 by Glen Davis, on Flickr

IMG_0567 by Glen Davis, on Flickr

IMG_0568 by Glen Davis, on Flickr

Left for 24hrs for the primer to dry properly and wear gloves took out the garden table as it was a lovely day to inspect for blemishes in the sunlight

IMG_0574 by Glen Davis, on Flickr

I used Humbrol model filler to fill the imperfections as there wasn't enough to warrant using an epoxy filler

IMG_0575 by Glen Davis, on Flickr

I'm going to let the filler set overnight and sand again tomorrow

After another quick fill and rub down. Then I spent the next 5 hours applying 0.5mm masking tape to mark out the panel lines. Trust me guys when I say this nearly ended my the love affair. It was super fiddle but after lots of swearing and 1 temper tantrum I got there in the end.

IMG_0583 by Glen Davis, on Flickr

IMG_0582 by Glen Davis, on Flickr

IMG_0581 by Glen Davis, on Flickr

I then applied 6 light coats of primer and left over night to dry and peeled away the tape in this morning

The don't show up well on the pics but seem ok to me. I hope when I give the final rub down we don't lose the line

While paint has been drying I Have been working hard on the decals using corel draw and will print to water slide decal paper.

Over the next few days I'll be adding colour to her

Started the colour coats today. First I wiped the whole model will Halfords surface preparation wipes which clean and degrease the surface. Next I mixed Humbrol 33 matt black to a ratio of 2 parts paint to 1 part thinner. Set my compressor to 15 psi and using my Iwata Neo airbrush gave the panel lines a light coat of black this will add depth to panel lines when over sprayed with colour layers. I also painted the windows with 5 coats of matt black. The Windows will get a gloss finish later

Next Job is to mask the windows after they are fully set which usual takes 24 hours

IMG_0604 by Glen Davis, on Flickr

I mixed the paint again 2 parts paint 1 part thinners the base colour is Humbrol 94 so far just one coat but she will receive 4-6 light coats before moving on to the next colour

I'm going to leave her well alone now until Monday as I don't want to damage the paint when I mask up for the camouflage and paint the dessert pink

Ok Guys were moving on to the next stage. I let the sand colour dry fully over weekend to give the paint a very good chance to full cure as I am going to use blu tack and tape to mask out the como pattern

lynx002 by Glen Davis, on Flickr

I bought 8 packs of blu tack which I rolled into sausages about 8mm in diameter and used them to form the pattern. A round profile is important as the will give a soft end when sprayed rather than a hard line. I then taped strips of magazine pages to mask the sand colour parts.

IMG_0614 by Glen Davis, on Flickr

IMG_0611 by Glen Davis, on Flickr

IMG_0612 by Glen Davis, on Flickr

IMG_0613 by Glen Davis, on Flickr

She is now ready to receive a coat of desert pink. When I spray this it is very important to keep the spray gun at 90 degrees to fuselage so blu tack shades part of the unmasked bits and if I get it right when removed we will get a nice soft edge to represent the freehand quick paint job applied in the field

Ok I mixed a batch of humbrol 250 dessert pink 2:1 ratio paint to thinners. Fill the bottle on my faithful old badger cheap airbrush which I have owned and used for 12 years now and still going strong.

ok this bit is very important you need to set your compressor to pressure so you get a light mist that isn't blasted at the model and holding the airbrush at 90 degrees to the fuse and ensure you move the brush keeping perpendicular you will get that nice soft feathered spray gun finish you see on real military aircraft and not the hard masked line. taking my time 6 hours between coats applied 4 light coats

After a very long 24 hours waiting for the paint to dry I removed the masking to reveal

I got a bit of bleed on glazed sections but apart from that an amazing soft camouflage scheme

I the bleeds where touched easily with a good flat bush and a slightly thinned colour

IMG_0626 by Glen Davis, on Flickr

IMG_0627 by Glen Davis, on Flickr

I am really pleased with the finish so far I have some more detailing to do before she gets a coat of gloss ready for decals next week as I need to let colours dry fully

I thought I would show you the actually helicopter I am basing my model on

IMG_0203 by Glen Davis, on Flickr

Yesterday I paint the last major part be for apply gloss coat

IMG_0204 by Glen Davis, on Flickr

I used Corel draw 12 to create the graphics and printed onto white and clear decal paper once the ink is dry they are spray with sealer to make them water tight

IMG_0629 by Glen Davis, on Flickr

The model split up ready for glossing. Gloss not matt I hear some of you ask. A gloss finish is better for applying decals and stickers too they tend peel away from satin and matt finishes.

IMG_0630 by Glen Davis, on Flickr

The whole model including parts that aren't getting decals will get 3 coats

Love hearing your comments guys

Had a little time today between chores and family stuff

I retrieved the model from my spray booth

IMG_0631 by Glen Davis, on Flickr

IMG_0632 by Glen Davis, on Flickr

IMG_0635 by Glen Davis, on Flickr

IMG_0636 by Glen Davis, on Flickr

I had enough time to apply the vinyl stickers I started with the white stripes which I believe are quick ident markings similar to d day stripes. I Used 7mm and 10mm white trimline for this. Applying carefully to ensure all lined up especially around the tail boom. I also used the wife's hairdryer to warm the trimline on the nose and tail to get it to go round the double curvatures smoothly

IMG_0206 by Glen Davis, on Flickr

IMG_0207 by Glen Davis, on Flickr

IMG_0208 by Glen Davis, on Flickr

IMG_0209 by Glen Davis, on Flickr

Next I applied BECC 20mm Low Vis Roundel to either side of the fuselage

IMG_0210 by Glen Davis, on Flickr

Using 6mm Tamiya tape I marked out the position of the aircrafts serial number. I carefully applied the 5mm BECC white letters to the tail. this is really fiddly

IMG_0211 by Glen Davis, on Flickr

Think they look well spaced and level

as its a nice day and to stop the wife nagging I moved her to the garden table out the way.

IMG_0639 by Glen Davis, on Flickr

I need to leave the glue on vinyl to fully grip overnight as the next stage involves waterslide decals
