RE: FALCON III COMPLETION
Sorry for the quality of the pic, it was a library book and did not explain how to do it.
I looked at the figures again and decided it would be simpler for a beginner like me to just buy the other servo. So will do, I will find the funds.
I temporarily screwed the servos in place in the fuselage to set all that up and install the pushrod tubes. It was only a setup procedure so I did not put the grommets or brass fittings in place on the servos, not a permanent installation. I turned the TX on to test the rudder rod installation and the servos went absolutely nuts (very noisy and moving spasmodically). Please tell me that is happening because I do not have the grommets and brass fittings in place on the servos and it is being caused by heavy vibrations and will be fixed after putting in the grommets to cushion the servos. I am using the same TX as I am for the LT-40 and YES, the LT-40 is off when I am doing this.

RE: FALCON III COMPLETION
I think you are going overboard on the aileron thing. I'm hoping ken gets in here with a drawing because you are making it a lot harder than it is. All you need is one servo in each wing and about a 4 inch push rod from each to each control horn from each servo output horn. Don't need no stinking bellcranks or tubes!!!!!!!
As for the radio, make sure the batteries are fully charged. transmitter output mode matches the RX mode PPM/PCM/FM. RX and TX antenna fully deployed but not right next to each other. Too close and the RX gets TOO MUCH signal

I already decided on my own not to use the complicated bellcranks, tubes etc and buy another servo.
RCKen did provide graphs below (thank you very much) and I am going to follow them to the letter (they are printed out as we speak so that I have them in front of me while doing it). I have already started my order for the servo and plywood sheeting from Tower Hobbies but I can not find a single piece of ply stick of about 1/4" sq to surround the openning as pictured in Ken's graph (I can only find bundles of 6 or more and I don't need that many at this time. funds will only allow single pieces at this time) Where can I find a single piece? I do not have transportation to my LHS so that is out.
Sorry for dragging this out like this, again I am doing as Ken suggests.
2ndly all components are compatible to my TX system cause I bought a complete flight pack for my radio system. Must be because no grommets inserted 1st, will correct that tonight.
Thank you.

Yes, you are correct bruce. I am making it more complicated than it really is (no excuse I know but I am still a beginner and am willing to learn) and that is my nature in life, not just RC, sorry to anger you.

I never heard of plywood sticks so don't look for that.
Use triangle balsa stock at the edges for support and glueing area.(square stock could be used too if on hand.
http://www2.towerhobbies.com/cgi-bin...?&I=LXJD13&P=7
Under the edges where the servo screws will go you will want to add a second layer of wood. You can cut strips of the 1/8 plywood and glue them into place if you like. I'd put 2 strips on each end if you do this UNDER the plywood plate and clamp in place until dry. Position servo, drill mounting holes, install and remove screws. Apply a drop or 2 of thin CA to harden the plywood holes and let set thoroughly before re-installing screws. You should be able to install the plates for less than $5 materials.
Ken is very busy at work but said to tell you that he will post more pictures/illustrations ASAP. Most likely this evening.

RE: FALCON III COMPLETION
I have now got the aileron situation all taken care of and I believe this setup will work.
I have almost all parts' dents and dings filled and almost all of the frame sanded and ready for covering and hope to have it started sometime tomorrow.
Here are some pics of my progress with setting up the ailerons. Now I just have to get some aileron stock to get it completed. And another S3004 Futaba servo to put in the fuselage cause I had to take one out for the wing. I bought one from my LHS but one of the tabs with the screw holes was broken off and somehow I have to convince him to replace it, convince him that I did not break it home. Hope he exchanges it.
Well, here are the pics.

RE: FALCON III COMPLETION
It would be nice to recess the platforms down between the ribs more wo not so much of the servo sticks up into the airstream. Best case scenario would be for just the servo wheel to stick up above the surface as long as it doesn't cause the bottom of the servo to go thruogh the other side of the wing. You get better linkage angles that way too.
If you haven't glued in the tri-stock yet it should be fairly easy to do. Put the servo plate approx where you want it to be. Turn the wing over and scribe/mark the new dismensions on the plate for cutting. Remember that the closer you get to the spar the thicker/deeper the wing is

RE: FALCON III COMPLETION
Sorry to say, but the assembly is already glued in place and cannot be ripped out without destroying the whole area.
Hope it won't affect the flying or anything.

RE: FALCON III COMPLETION
At the time of those pics there was no glue (sorry) but last night (a day or 2 after those pics were taken) I glued it all in. I stored two separate days worth of pics on the camera but downloaded it to the computer today all together in one folder.
There is about 1/8" of space left from the bottom of the servo to the bottom of the rib.
Besides me not encasing the servo deeper in, how does the assembly look? Will it fly good?

RE: FALCON III COMPLETION
tigerdude426, just noticed in one of your last pics, you might not want to permanently attach the wing servo extension wire like that, you will not be able to change the servo later without opening the covering. A better way might be to place a string through the wing and tape in place while covering, then pull the servo wires through when done. RCKen suggested this method earlier. When replacing the servo later on, just tie a piece of string to the end of the servo extension before removing the servo. When you are ready to put the new servo back in, tie the string to the new servo extension and pull back in. Any way just a heads up.

RE: FALCON III COMPLETION
Looks like it should work but I agree that you should NOT tie the wiring to the frame. If you need to swap servos, BIG trouble. Cut it loose. Take a piece of thread/string and tie the connectors together so they cannot accidently come apart. You also want to be able to pull on them to route replacement wiring if needed. Also not much fun to cover the wing with the servos installed.

RE: FALCON III COMPLETION
Here is the finished wing. Well, base color anyways.
I am thinking just a simple red 6" or so wide band on the bottom of the wing and blue or black star-bursts on the top of the wing and stabilizer with dark-blue or black tips. Just keep this design nice and simple.
Would like to have had less of the servos showing but I only had about 1/8" from the bottom of the servos to the bottom of the wing.
Stupid question (or comment rather
) - - - I do not see any way of removing the servos without 1st having to cut a small portion of the covering away near the center of the wing so as to be able to unplug the servo from the Y-harness.
But I guess that couldn't have been avoided. But I am not seeing any need in the future to remove servos anyway. Will probrably crash the plane before that comes up.

Close-ups of the servo/aileron installations.
Last pic is a close-up of the canopy. First canopy I ever did, think it came out OK. Used canopy glue for that, reinforced with drops of thin CA

RE: FALCON III COMPLETION
Here is the completed Falcon III. I actually finished it over a month ago, but just realized I didn't post the completed plane yet, so here it is.
