adding ailerons
 

I have a luscombe silvaire I would like to add ailerons to. This is about my 4th build. Looking for tips to convert from 3 channel to 4. Thanks.

Would be easier to answer if we had some more info - size, structure, pics, is it already covered, etc.
Not all designs benefit from ailerons.

The old way was to build the wing and the saw out the area for the ailerons.

Shore up the sawn edges with balsa

Thanks for the info. I have not even started the build yet. Just reviewing ideas. Seems simple enough. Just wondering if more strengthening is needed in the wing. It's a Dare kit, 52.5 span. I'm considering a servo for each aileron.

RE: adding ailerons
 

If its not built yet your task will be less difficult. Figure out the size and location of the Aileron and build it into your wing.

RE: adding ailerons
 

Since you haven't even started it yet I highly recommend adding ailerons. Heartely disagree with not useing ailerons. Makes for a totally different and far better airplane.

Thanks TedMo, I agree.

RE: adding ailerons
 

When adding ailerons to an airplane intended for rudder control then it will be neccessary to reduce the dihedral substancially. If you do not the ailerons will be very unresponsive.


On an airplane of about that size typically will have around five or more degrees dihedral for reasonable control on rudder and cutting this in half will give a reasonable response with aileron Which in most case will turn out to be about scale dihedral.

Thanks john, I appreciate the info and will put it to use.

chuck mary,

I have a JMD Models kit (now out of production) that has glass fuse and of course ailerons. I believe it is about 72" span. The plane is unbuilt at this point. The plane can be built with fully sheeted wings (simulates metal covered wings, which some planes have) or just built-up (simulates original standard fabric covered wings.)

I have had a Saito 60T twin that I bought just for this plane. This engine is as smooth as an electric motor.

If you want, I could post pictures of the plans to allow you to construct the ailerons in a scale manner. I believe the plane is very much to scale, as the owner of JMD Models owns a full scale Silvaire from which he drew the plans.

Regards,

Randy Little

Thanks, that would be awesome.

I will try to get the kit out and take the photos tomorrow.

I realize my posting left out a crucial detail, if not obvious, the kit I have IS a Luscombe Silvaire.

Here is the construction manual for the Great Planes Slow Poke 40

http://manuals.hobbico.com/gpm/gpma0492-manual-v1_1.pdf

from this you can get an idea of relative aileron size and construction technique

Thanks for the pics. Good info to have. I had started on one wing half and the info confirmed what i was doing. Thanks again for your time. Would love to see some pics of your luscoumbe.

chuck mary,

Attached please find the photos of the ailerons on the JMD Models kit.

This plane has a little larger span than I remembered: it is 78".

To orient you, one pic shows the ail closeup, the other a 1/2 wing panel.

The length of the one wing panel is 35 1/2". The span of the aileron is 13". The chord of the wing is 9 3/8". The chord of the aileron at its widest point is 3 1/8". The relatively short aileron then has a chord of exactly 1/3 that of the wing. This is relatively large, but the ailerons are pretty short on the Silvaire.

Hope this helps.

Regards,

Randy Little

Thanks for the pics. Appreciate the help.

Go to my build for a Jerry Nelson Pegasus in the Vintage forum, http://www.rcuniverse.com/forum/m_85...tm.htm#8507065 , for another idea for building ailerons using the aft tips of wing ribs. The Bruce Tharpe design is very good.
