YA Stingray

Hello,
After deciding 120 mm is not for me i did a bit of trading with Simon <edf crazy> and came home with a kit to build<remember we all used to do it that wayi had one many years ago with a homebuilt Wren turbine and is was a bit of a pig to fly as the auw was way too much for such a small airframe.Anyways this will have a Het 90mm fan and a Het 700 series motor on 10s 5000mah lipos and to finnish it off one of Tams nacelles.I did a search on the Stingray and although several people have talked about it not a lot is apparent when it comes to battery placement, how to mount the nacelle etc so i will just do my own thing.I will film the wings in profilm and may just buff the fuselarge as i want it nice and light.
If anyone can offer any advice or modifications please chip in,
cheers Euan.

Ns,
Thanks any more info will be great, i think a 120 mm set up is too much for the Stingray and may lead to problems like i had with my original turbine version<too much weight above the thrust line> but hey it may work ,Steve how you doing i remember chatting,photos of your nacelle and battery position will be a great help,also can i ask how much it weighs and how many watts you have?,
Do you think i could drop the cell count to 9 or 8 s ?
cheers Euan.

Hello,
After spending a few hours going over the build manual and sorting out the pre cut parts i have done a little bit of work,the wings have had the elevons cut out and te and le added.Rather than use epoxy i prefer to use a good quality white pva as i find it easier to sand and a lot less expensive,
tomorrow i hope to get the elevon servos mounts sorted.
I had a look at the rudder servo mounts and found it impossible to fit as per the manual? any ideas chaps? also the vertical fins locate in a neat tube clamp but still require an allen bolt fixing at the leading edge,apart from looking crap do a really need it ?
Tam can you give me an idea on how to mount your nacelle <keep off the green bottles and answer your e mails>
cheers Euan.

Hello,
whilst waiting for my retracts to arrive i have finished off the wing and , hinged the elevons ,fitted the servo mounts,mounted the canopy and catches and sorted the air brake out I have a Tams nacelle waiting for my edf that should be about it before i prep and paint it,
all up weight so far is just under 4.5 lbs so my target is not too far off,
cheers Euan.

Well,
my retracts arrived and to my surprise HC sent air up spring down along with a set of sprung oleos < i ordered the less expensive ones> fitted with little hassle apart from the oleos that i had to cut down.For the nose leg i found a home made by me at school <30 yrs ago> trailing link that looks spot on
The speed brake is a very poor fit and will need fairing in with filler along with a magnet to hold it down,
maybe get around to some more building tomorrow?
cheers Euan.

Hello,
I managed to fit all the retracts along with the air tank, fill valve etc and to my delight it has held air four three hoursiam however very dissapointed with the Tamjets nacelle its full of voids in the glass work and the hatch is too small to fit it neatly:mad , still after a few hours filling and sanding will see it sorted,
cheers Euan.

looks great ...too bad about the pin holes ,i tried priming in the mold with my Nacelle's ...but i always had voids,so i make my own gel coat (epoxy) and i have way less voids using that method,not perfect but very few pin holes.the seams require a small amount of filling and sanding .this is looking good ...very sleek looking airframe.

Roger,
perhaps Tam should get you to do his glass work,if i had actually paid cash for it <it was a trade> it would be on its way back to the US.
Still the weather at the moment is poor so i have plenty of time to sort it out,
cheers Euan.

Too bad several great other projects are waiting on my bench first.

Euan.

Nice build building mine at the samte time and posted my build at rcuniceverse.

Bought a already started kit and had to do a lot of extra work fixing wings since the ailevons were badly cut and build.

What fan and motor setup are you going to use?

Cheers,

Juan

Hi there
I tried to take a few photos with the I phone of the interior of my Stingray.
The Batteries are made up of 2 6S packs which are actually 2X 3s packs in series.If you look there are two boxes made up to take each battery pack.They start just inside the wheel cutout and go twords the front.
I hope this helps.
Photos are not great.
Cheers
Steve
