doesn't matter who "they" are, really.
Geez, you're lucky - you get to say one word before they ignore you.
The good news is, I still just grab a plane (or 3) and head for the field when the mood strikes. ... and I usually leave the cell phone at home.

um, yeah, I got nottink. I say, they do, whatever they were doing before I say. Of course, the also found out the hard way that if they don't do as I say, things go missing. .

I have to admit, the LT-40 does make a good 3 channel plane too. My aileron came undone from the RX, so I had to land with rudder only. I made it look pretty good too. In front of spectators too.

Oooooooo, I had an aileron come loose on my CG Sr. Falcon several years ago. Took a lot of time and loooooooong turns to get her lined up to land. No fun at all with that one and 3 channels.

The tricky part is that the LT has a sticky rudder and is setup with long throws, so my turns were a little on the steep side. I am just grateful they were in the neutral position when they came unplugged. My LT can turn inside itself, 10 foot loops is what it looks like, It will also to outside loops, though those are rather large so I make sure I am high enough, but my favorite one is my ribbon loop, If I had smoke on it they would look just like those ribbon stickers you see for breast cancer or some other cause.

If I had not said something no one would have ever known I plugged the servo wire in backwards cause the Kadet flies perfectly fine without ailerons.
Our other favorite thing to do with the Kadet is get it up in the wind. Out here where we fly there are few obstructions and we get nice straight consistent winds about mid morning on some days. It is a standing challenge when the wind comes up to try to land moving backwards. Outside of the little electric profiles, my Kadet is the only plane to accomplish it

Thanks guys, it seems to be a good system so far.
The other thing it does for me is gives me the ability to raise and lower the aileron if I feel I need to adjust the gap between the wing and leading edge of the aileron. I set it for now at what I think should be a good spacing so air can flow over the top of the aileron at high angles of attack in slow flight. I might be day dreaming but we are shooting for the ability to pull off one of those impressive short landings you see STOL planes do on U-Tube.

The flaperons are a big part of the experiment so I have to be sure I do a good job on this part of the build. And of course there are going to be setbacks. Like this one:
I built these nifty internal linkages to run the ailerons and still keep the servos weight in the center. Looks like it should work right? Wrong!! After hooking up servos to the new ailerons I find there is too much play in my system and I am going to have to scrap those and regroup.

I could see the "slop" at the bearing surface of the horizontal rod that connected the two 4-40 size horns that came out of the collars. lets see if I can do a better job of explaining. In the pictures you see a 4-40 screw in each of the collars at either end of the horizontal rod. After I attached linkage to those 4-40 screws which were about an 1-1/4 long, the leverage created at the collar was enough to make the horizontal rod jamb against the side of the nylon tubing I used as the bearing surface. It was a good fit but not really snug enough because it moved laterally. Which allowed about a half inch of free movement at the end of the lever where the linkage to the aileron was attached. The slop was enough that I could move the ailerons almost 50% of their travel before the servo would move. Some "give" in the linkage was expected but this was way too much and I need that linkage to be solid in order to trust adjustments when I fly this thing the first time. Adding to the problem is the lever on the aileron is real short.
Long story short there were just too many opportunities for slop in the system and it had to go. I thought about ny-rod but there is actually a lot of slop in that as well and I would have had to plumb it through an already sheeted wing with a very tight curve.. My only choice was to go ahead and move the servos out under the wing which gave me a straight shot with simple linkage hookups. I'll do some pics tomorrow and show how I have the linkage setup.

I posted on the other Brotherhood thread already.
If anyone is interested, I have designed both a Hog Bipe and Kadet Sportster, both foam, with 50% and 100% versions electric powered.
If there is interest, I would be happy to post the plans.

Here are a couple pictures of the current setup. There is still some slop in the system because of flex in the pushrod, nylon servo arms and control horns. As you can see the linkage goes between the wing and the aileron which leaves a very short arm for the aileron horn and is part of the "slop" problem but I can't connect at the bottom of the aileron and I really don't want to go out the top of the wing with the linkage. So this is the current preferred setup.
