thanks mutt , heres the way i finish her
ok mate first to seal it i use 2 part finish resin


which is available for those in australia from , nitrodude http://www.nitrodude.com.au/catalog...roducts_id=1108 and firstly i fill the fuse low points with the home made filler of talc powder and model dope ,and a small point here , if you find a shop selling model dope in australia let me know as it hard to get due to the fact that you now have to have a liscense to keep it on premises, then mix up the resin ,using even parts , and make sure you keep the mixture pretty even as it will go rubbery other wise , a good way is to put a amount from one bottle into the mixing container , stand the bottle back up for a min then mark where it settles on the bottle , and now mix in the second part ,and stand again and check that it is at the same height as the first bottle ,you only have abaout 20 min work time with this once mixed so mix it up then with a 2 inch wide brush paint it on in a llight coat , dont worry about trying to get it smooth ,just make sure you cover the whole section in a light even coat then set aside for 24 hours , now dont sand it yet but mix up another batch and paint it on in a light even coat again , and then put aside for 24hrs , now when it dries you should have a nearly perfect smooth finish , give it a sand with 80 grit papaer , and then another with 320 grit papaer and you will have glass like strong finish , ready to be primed and painted , you amy still find some low points in teh finish so mix up some more filler and fill then sand and prim , i find it easier to prime it straight away once you give the finish resin its final sand then look for the low points to be filled , easier to see . you may have to fill and sand a couple of time s to get a perfect finish .as for primer any sandable primer from an auto shop or bunnings will do , once you have filled teh fuse to a perfect smooth finish prime it again then sand it back to check that there are no more low spots then apply the final light coat of primer and apply your paint ,make sure that when you are painting the primer or the paint that you use light even coats , dont hold the can too close to teh model and dont rty to cover teh area in one application but rather in a couple , at 10 miin intervals so that it doesnt run , oh and dont do it at night near a light as the bugs will land in it and stick lol,the paint i use for priming is white night super primer its about $12 a can and gives the grey finish you see on my apache .

as for the canopy windows mate dont fret james has vaccum formed all the windows very nicely so its taken care of ,im not sure if ill use tehm yet depends on teh scale cockpit if i can dooit or not ,will see when i actually place the ergo mechs in for teh first time ,i have some very nice desert cam pics also ,mine is going to be us army drab ,but that could change ,by the time i gett to painting the final cam on her

ok i have spent the last couple of hours adding a lot more detail to the fuse ,the tads system is almosy=t ready to mount ,and will work in sync with teh m239 30mm chain gun, i am also closer to working out my lighting setup , also , over the last week i have aquired a helitronics light controller , with a heap of luxeon lights and leds ,i have also bought a lighting kit from http://www.ncweb.com/biz/dan/RCLights.html i the states ,which arrived last night, i had a quick play with it in my quick of japan ep8 cobra ,and it is a ready made easy to use light set up which is great for those amongst us that would like to have a simple no hassles or fuss basic light set up on our model , i am also in contact with ross from http://www.lightingforaeromodellers.co.uk/ who is sending me his product list and is going to help me get a lighting setup sorted out also , in short i am going to try all three setups and go with the one that best suits th apache , the other two will then end up in the e-cobra from approach engineering and teh 90 size cobra ,,i am favouring teh helitronics for teh 90 size cobra as i want to put a lot of detail into it ,so once i have a bit more time with each setup i will put my thoughts down here .
So back to the building there is little to do to finish of the nacelles so this is where i will start.so next on teh list is sheeting teh top of teh nacelle , simple and quick , there is plenty of 3mm sheet so you can overlap a bit then sand back , im the cuastious type so i loke to give a little excess then sand off

then just to show you how she is taking shape here is what she looks loke with teh canopy ,every step just gets more and more exciting and the shape of teh apache takes form

right then , locate the two engine nose blocks ENB for either side ,glue the two parts together for each side , now the important bit make sure you make a right and a left when you start to sand to teh final shape .

i kept refering back teh the cd that james includes in teh kit , there is over 200 pics there of teh apache he flies , and you simply cant find anymore detailed reference when starting to sand and shape for teh correct detail, and especially now as i am adding the final detail ,i have it open on my desk top all the time , im lucky enough to have my computer out in teh gargae so i can refer to it always .
so have a good look through teh pics as it will give you the best perspective on how to have the final shape of teh engine blocks at the front of teh nacell , again i start of with 80 grit to get teh basic shape tehn use 120 ro smooth it up and finally 320 to get it perfect for the resin coats .
one thing i did change or add as it may be was the top turtle deck sides ,on the full size heli its a smoother and less pronounced step from the side of teh top deck to teh transmission bay sides so i added 5 mm of balsa to teh side of the top deck to bring it out closer to the side of the transmission bay , then i jsut sanded and shaped to get a good curve , so finally we end up here


this is where i have to say that i really got excited and i think i built well past midnight this night as i didnt realize the time

this pic shows the nacelle shape starting to form , i used a razor plane to get a head start here

just thought id show you guys teh mechanics that i am using in hte apache . she was designed around century hawk mechanics , but seing as i have a couple of ergo 30s that i have converted to 50s sitting here ,that is what i am using ,have been waiting on my clutch and it arrived yesterday from pete at http://powergrunthobbies.com.au/.so i finally got to fit my os hyper 50 today with teh hatori 541 manifold and teh 540 tunned pipe , this will give me the clearence i need

as i only have experience with tt 50 pro motors in my scale helis i was interested to see just how good these motors are ,well i have to say that i have always had a pretty reliable performance from my tt50s , but the moment i spun teh starter on hte hyper for teh first time she sang straight into life and into a smooth stable idle , definatley think my littlebird will be getting stripped down after teh apache is finished and getting an up grade to a hyper ,,so for teh first tank i just set the needles and let her idle over for half a tank then sowely increased teh throttle to about 50% for teh last half ,got her light on the skids but didnt go any further ,will run another tank in her tomorrow doing the same then ill get her up into teh hover .

heres another pic of teh apache , have started working on the tail now ,as soon as i am happy with teh ergo flying and have the hyper run in , ill start putting the mechs in

sorry for not keeping this up on a regular basis guys ,just been carried away detailing ,hte fuse plus putting time into teh ergo 50 to set her up to go in ,ill go into a brief discription of the nose assembly,which i skipped ealier as i was waiting for some parts ,you might remeber that i was waiting for the forward fuse formers to complete the fuse and nose setup ,so when they arrived it was a simple process of using epoxy to glue the left and right side fuse sides in place , this then allowed my to finish off the fab (forward avioncs bay)and then the nose section ,
this is how it looked leading up to the completeion of the forward fuse

so with teh forward section complete i was then able to move on and construct the nose section ,and also the TADS and PNVS equipemnet which sits out teh front of teh nose ,locate the four sides to teh nose ,and CA together following the manual so that you have the correct parts top and botoom .next you need to add extra fillets and stock inside to allow you to then shape the nose section to teh scale outline ,next place the front plate over teh structure so that the top and bottom of teh plate are flush ,trace the outline then remove ,now sand to that shape ,and using teh pics on the disk james includes in teh kit .
once you are happy glue the front plate in place and tehn the support plate ,you now have the complete nose section

well guys it has been way too long since i posted about the apache , i have not stopped her altogether although things have slowed down somewhat due to work , but the good news is that she is a lot closer to flying now , pretty much all i need now is to source out a custom length belt to go from the ergo mechs to the tail adapter as it was designed for a raptor that has a much larger final drive gear ,so i am currently searching out a belt , then all i need is a new engine as i had to use my hyper in my md530 littlebird as the old tt50 pro finally gave up the ghost .here are a few pics to show the progress i have made over the last few months ,the helitronics light controller is in and superb with the luxeon lights , although i still have to put in the landing light , the mechs have been fitted and the tail adapter and flex drive are in and set up , have connected the tads and ihads to the rudder servo and the tail plane works off the collective ,and the m230 will be set up to work off the roll axis,i have also made a suspended ,swiveling tail wheel thanks to Emile for his setup.
for size comparison her she is next to my 450 ep dragonus


front on showing the tads and ihads

in this pic you can see the rudder servo ,which has the ihads and tads connected to it , closest ,and the other servo is for teh tail plane that will be coupled off the collective the wiring is for the helitronics light setup

this next one shows you just how tight it all is and how much larger the ergo mechs are ,is a good indication of how helis used to be 5 years ago

and here she is , almost complete , still have some more surface detail and decals to add ,but pretty much if i had the new hyper and the belt she would be able to fly


i will get back into the construction post so that you can see just how easy it was to get to this stage
