Res


It would be fun and cool to mix the spoilers for some aileron effect, although that would be illegal in some competitions such as RES I understand.

I tried it on a Jester... wasn't worth the mixing in the Tx. Polyhedral wings were to stable.

mixing spoiler/rudder


I did it in one of my Sagitta's once and it was not the difference of ailerons, but it was helpful in the LZ. And no it would not be legal in RES.,... Brian

EZ Spoiler Weights


The overall weight is minor. The total mechanism, servo and linkage, for each spoiler weighs less than 1/2 ounce. All of the parts are available at your local hobby shop. This is a perfect setup for your Riser 100.

That's a really neat set up.

Looks like it's been around awhile though.

Brian Joder thought of this a few years back and published it on his website.
It was used on the Superhawk sailplane and still is today.

Here's the link:

The spoilers and rudder are mixed with a switch. Makes a HUGE difference in roll rates (snap rolls are possible). I believe it is against RES contest rules to use it during sanctioned events as per AMA rules though...

Are you serious?

So above the wire is an extension of the servo arm? Looks like no movement of the wire through the metal parts on the arm

edit
Wait no, the wire moves through opposite to the first post? just looked at the link

This is my first EZ connector system which I used on a small electric sailplane about 5 years ago. The rod slides through the two connectors and the 90 degree bend attaches to the spoiler arm. A bit difficult to install but worked nicely.

weight notice is negligible in a model the size of the Riser. NO weight penatly for your model. very easy to setup and very little maintenance. Always anothr way to make somethng work. To simple in design.......

Yep, that's a very similar type of setup that I used on my thin wing small servo section spoiler. The only difference being a tube mounted to the spoiler instead of a control horn.

QUESTION: How do you determine the distance between the end of the outer servo arm bushing and the control horn mounted to the spoiler? Do you just wing it?

I'm thinking there must be a way to determine the optimal distance to get the most amount of spoiler surface travel for the least amount of servo arm movement and that that would be tied to that distance?

ATJURHS:
The distance between the spoiler EZ connector and the servo arm/connector should be close without touching. This gives the greatest torque for holding the spoiler closed. As we are only talking fractions here, any near distance is fine.

The least amount of servo travel for the greatest spoiler travel is a function of the distance between the spoiler hinge line and the servo pivot point. However just placing the servo near the hinge line is very adequate for total spoiler travel. I never open the spoilers to 90 degrees, prefering something in the range not exceeding 30 degrees. My Topaz is now at 22 degrees and may be reduced when finally tuned. My DANNY RES with the mono-spoiler was at 15 degrees. The measured spoiler openings were: Topaz 1.0 inch, DANNY 5/8 inch.

The secret of this linkage system is the addition of the third or spoiler mounted EZ connector and the one lock screw. This allows the wire slide rod to be straight. The earlier versions required a 90 degree bend in the wire at the spoiler end which made the overall installation difficult.

When I decided to use this system on my new Topaz-S I finally realized that 3 connectors was the secret. How/why I missed this during the development process, dating back to my first version with the little electric sailplane, and other RES planes, I don't know. But the light bulb finally came on and as they say "The rest is history".

The three EZ connector straight rod linkage is simple, works great, requires no adjustment and is EASY to install.

Thanks for this thread, you're right on time. I've used the technique on my Miles build, it looks like it's going to work great! Pics over on thermal, Miles thread.
