1/2a Stealth Sport RC Plane

The trick to using cables is to make sure the sheaths are securely anchored at both ends. Get it all installed and working correcly before covering.

Hope this sheds some light.  If you'd like, I'll write up a step-by-step of how to install and trim the aileron servo, cable and sheaths.

Wow Dave a great idea..So far I have often been discouraged from adding optional ailerons to my planes because the usual bent rodwork moving them was difficult to connect to the servo and to lead out from the wing along the trailing edge. I will definitely try this bent wire way the next time I build an RC plane.

Well, I did end up gluing on the wings last night. This evening, I have just dribbled in some wood glue into the joints on the bottow where I had to adjust the wings to be equal at. So, it is now currently sitting upside down, so I did not take a picture. Also, I did kinda follow the instructions, so covered the wings first. Well, as I had to clamp them to the fuselage while drying, I had to cut out the first rib bay on each side so I could clamp them. No biggie, just a quick little pacth tomorrow. Another benefit of the cheap doculam.... I will try and remember to snap a picture tomorrow.

The next big hurdle will be to hinge the ailerons. What type of hinges will I do?????? I am seriously considering one of two types. A 'Monokote' hinge using doculam, or doing my new favorite of a sewn hinge. Later this week will tell.... Stay tuned.

Hi Andras, it's not really a bent wire pushrod but a flexible cable.  

Dubro and Sullivan both offer them, folks usually use them for throttle pushrods on larger planes.  They're not stiff enough for control surfaces on much more than backyard flyers, but they're perfect for slower 1/2A as long as the unsupported run is short.
Here are both brands, the Dubro outer is a bit more flexible and easy to install, but the need to anchor securely is even more important.  They weigh about the same.



Both require that you solder on a threaded coupler on both ends and use a nylon or metal clevis.
All the necessary parts are includedd with both sets.

Thanks Dave, yes I had them in a balsa kit before, they are thin Bowden wires that are OK for pulling the control horn but ned to run in a sheath up to the horn tip less the tip throw otherwise they will buckle when pushed. But the idea of how to lead them out for aileron control without fussing with an aileron drive shaft lead out through the trailing edge is great.

As to the hinges I often use the glass fibre reinforced textile, or, cut them out from thin plastic sheets we used to draw and write on for old school projector presentations.

The flexible wires work great for ailerons with one central servo. The connection to the control horns can also easily be made by bending the wire to shape and then letting some solder wick into the end:

Well, nothing much to report other than the wings are on, ailerons attached using doculam (this is a first for me using it as a hinge material), holes in wings covered from my having to cut the first bay open to clamp the wings to dry. Tail is also attached now. I am now thinking my next step is to get the worst part of building over. The installation of electronics..... Still got to determine what servo(s) to use. I am thinking a 9g for the elevator, and possibly an HS-81 or equivalent on the ailerons. Anyways until then..... If I cannot get my electronics sorted out, I will scuff up my wings to get ready for paint. AUW as seen pictured is 7.5 oz. Also to note. There are a few wrinkles and ugly spots in the covering, but hey, this was a 'quick build' to see how I like the plane. If I like it, I will probably build another, but take my time and do a nice job like yours Dave.

Looks awsome, congrats..I would certainly drop a good TD049 in it because this bird seems to want to soar real fast!!

I also stragger when the airframe is ready and the servos are to be packed in...that is the point in my build when the quasi-professional look of the plane turns for the worse with all my garage-tuning efforts that go into placing the servos on a stand in the right position...

Wild looking bird , should fly well seems to have lift to it .

If you want the plans Eric, just pm me and I will send them right over should you like.

I've got templates in PDF format, printable on 8.5 by 11 paper too, for anybody interested.

I was digging in the kit closet looking for something to throw out and found a water damaged box that said 'Wood'. Opened the box and was surprised to find most of a kit for this 1/2 A Stealth Sport. It had some hardware missing and no plans. This box was from a close out or an estate sale years ago. So Now I an in need of a set of plans or at least a photo of the plans. Any help will be appreciated. Note: I have flown the Black Widow over the years and really like them.

Send me a message with your email address and I will be able to help you out.....

Glad to see some others have this plane. Anyone happen to have a link to some pdf templates for 8.5x11 printing?
