The old wings never had spoilers, and it sorely needed them due to its wing-loading. So, i want to add them to the new wing set. Before i sheet the new, i know i need to run a channel for the wires, but i want to garner some opinion on spoiler options, placement, and wing strength etc.

Now, i want to be able to do points landings with this, so the spoilers need to be pretty effective. It will never see a winch launch, just hand-tows and shock-cord bungee launches. The wing will be built with two tapering sub-spars about 1/3 length of each wing which keep in contact with the bottom skin. These will also house the brass joiner tubes. The sheeting (1.5mm balsa) will be continous 1.2m out from root, then a seperate sheet to finish off the last 30cm.

The old wings were layed out as above, and are plenty strong enough for the launches i gave it. So, this thread isnt really a how to make the wing stronger thread, rather about spoilers and the cons of adding them from a strength point of view.

So, im open to ideas about how and when in the build to add the spoiler bays. And also to the sizing and placement of the spoilers - pros/cons. My initial thought is to have a long and low spoiler which deflects 90 degrees made from TE stock (3/4" - 22mm or so) and about 20cm in length. Placement would be perhaps a bit less than 1/3 the way out so that the sub-spars add to strengthen the weakening caused by the opening in the top surface. I was just going to cut out an opening from the top (but not through the bottom skin) to house the servo and spoiler as deep as it needs to be. I could line the bay with balsa or ply glued against the foam sides perhaps to transfer load to the bottom skin? Or would that not acheive much? Or perhaps lay up some glass under the balsa in the area i will cut out the bay??

The wing will be 24mm thick (at thickest point) and 220mm cord and is a S3021 (IIRC) @ 11.5% (IIRC). The spoiler will be positioned about 20-30mm back from the thickest point of the section. Does that sound ok, or should it go further back? or forward?

Thoughts, ideas? Help?? I want to get it properly sorted before the skins go on.

I know where i can get oracover and solarfilm and solite, and all the others, but not Monokote. I would strongly prefer monokote. Anyone?

So, i'll throw out a request for qoutes for one of you expert builders to build it for me - without radio gear, but with servos. It want it to have the spoilers option, built standard. Quote to include doing a fully sheeted balsa d-box and covering in monokote.

Any takers?

PS the offer is only (trademe) valid for the next 3 days, and will only accept the trademe offer to buy the kit, if someone wants to do the build.

This is a free service for you. Please keep all communication between yourself and potential builders right here on this forum. That way we can all see who is building what and for how much.

Treat this thread as your place to initially seek model building services. Once a builder has contacted you on this thread, please open a new thread in the Builders Zone to iron out the details etc.

Its the Big Bird DS Carbon version from Soaring USA; http://www.soaringusa.com/products/prod ... g=big+bird

It will be interesting as its a bit smaller than what I normally build so my fingers have been on a diet

Might take a bit longer than normal as it is complicated by needing to do a 2.4GHz install (there is a LOT of carbon in it). He has a 9300 carbon fuse receiver, and have an additional carbon fuse satellite receiver coming for 4 total antennas.

Servos are Hitec HS125's in the wing and a HS5085 for the elevator and rudder.

I wont be starting on it for a week or so as I want to finish Marks M60 fuse first and need to order in a couple of small bits'n'pieces.

No wiring harness came with it so will be making one up from scratch. I hope to be able to document each step so you can all see whats involved and how to assemble a moulded model but we'll see how often the camera remembers to come out.

I'm looking for someone to build me a rite wing. Haven't flown one before so looking for a 'beginners' version/model.

Anyone know of somebody that builds rite wings?

Needs to be shipped to Melbourne Aus.

cheers

I will courier it to you tomorrow....can you PM me your address details please

Mate, I forgot to mention, I will need a slot installed to take my FlyCam2 ECO - see here:

FlyCam2 ECO at our online store

I will discuss where I want this once you have the model in front of you....

Build thread here: http://rcsoaringcommunities.co.nz/viewtopic.php?f=13&t=739

Also...I will send you x4 AAA battery pack, 2.4 gz receiver, switch....for install. The switch is a little big, its a new JR one. If you are adept at making quality DC Switchjacks, I would pay a wee bit extra for one. By quality, I mean metal plugs - not Jaycar style plastic ones. I have used these before and they break...up to you where you install plug.

Happy to now make it $60 - now including install of battery, rx and switch (mine)

This new fuse is a little longer than the original M60 fuse. A quick balance with the wing slid in shows the CG will need a wee bit of lead in the nose( not much though) - if the battery pack is sitting forward in the slot provided.

The wing will be removable...not sure how to afix it in yet....the wires for the servos exit at the LE of the wing - right in the centre. So there will need to be a small hole in the LE recess in the fuse entering into the rx compartment for the servo wires (with universal plugs) to go thru.

Post any questions etc here....

Cheers Les, can't wait to fly her again!

Are you a competent modeller? Have you been building models for years? Well, now you can advertise your building services here in this thread. Please advertise your experience and the types of models you are prepared to build. Also indicate approx hourly rate, or total cost per model.

This is a free service to both builders (non commercial) and those seeking someone to build for them. All I would kindly ask, is that if you do receive paid work from this forum, please make a forum donation. (click Donate link at the top of the page). Please don't include phone numbers or email addresses here. Please keep all initial correspondence between you and your client public here on the forum. That way we can all see who is building what and for how much.

Treat this thread as an Builders Advertisers Master Thread. Initial contact can be made on this thread between Builder and client, but then please open another thread in the Builders Zone to iron out the details etc...

It would also be great if you would do a build thread for each paid model you build.

(Please note: if you are a commercial model builder, you cannot advertise your services here. Please use your common sense regarding this. If you are a commercial builder, you must either be authorised by me to advertise here, or you are a paid up Forum Advertiser.)

If you advertise yourself as a competent builder, you are authorised to place the following builders banner in your signature. Simply right click the image below - select 'Copy Image Location', and in your signature (in your profile) Click IMG and insert the image. You can also include one sentence with a link to your advertisement to this build thread in your signature too. That way, each post you make on the forum, you are advertising your services - in a discrete way.

The service we provide is simply to bring builders and pilots (needing models built for them) together. We do not guarantee or endorse the skills of anyone on the forum - unless otherwise stated.

Where I have personally seen the excellent craftmanship of builders advertising their services on this forum, I will provide a "Master Builder" Rank, that will appear under their avatar in their posts. This will indicate to you that these builders exhibit excellent modelling skills and craftmanship. Modellers that do not have this rank may well have these skills - but I have yet to see them personally. The "Master Builder" Rank should provide you with a level of assurance about the skill set that a particular builder is capable of.

This is the "Master Model Builder" Rank.

This will NOT appear in the signature of a modeller. It will appear in the 'Rank' under the Avatar. You can see my 'Rank' is "Administrator". My rank appears under my avatar (pic) on the left of my posts.

Enjoy!
