The S6R is easy to set up; it's just that the procedure is a bit long. I won't go into great detail, but I will mention several important steps.
Download the latest software to the TX micro SD card. Instructions are on the Internet.
Download the latest S6R firmware and put it into the FIRMWARE section of the SD card. The S8R uses different firmware. BE SURE you use the appropriate firmware for your location. One version is for the U.S. and the other is for most of the rest of the world. This is IMPORTANT. The file name will give a clue, but they change the format from time to time. Look for part of the file name to contain "FCC" for the American version and perhaps something like "EU" in the firmware as part of the file name for the rest of the world. You'll figure it out.
Make up a 3 wire cable to connect the smart port of RX to the connection in the bottom of your Q7 transmitter. You must reverse two of the wires in this cable; instructions are on the Internet. Be sure you connect the correct end to the RX and the correct end to the TX and make sure you have them plugged in right-way-round. Check the Internet.
Now push the appropriate TX buttons to find the FIRMWARE page, select the firmware for your receiver, and flash the receiver.
When flashing is complete, disconnect the special flashing cable you just made up and keep it in a safe place so you don't confuse it with a servo extension.
Hook up the RX to an ESC and battery and bind it to your TX.
Now go to the TX SCRIPTS page and calibrate the RX. This involves following the script instructions as you orientate the RX gyro by placing the RX face up, face down, end up, end down, right side, and left side; i.e. all six sides. You push the enter button each time. Be SURE to wait for the yellow LED to quit flashing before you go to the next position. Now the RX knows which way is up, so to speak. You only do this once when the RX is new.
Now run the other Lua script (use the same script for either the 6 or 8 channel RX. I think it's called Lua SxR) and tell your TX that you're flying a DELTA configuration. Accept the default on most of the other selections unless you have a good reason not to. For example, I mount my RXs with the pins aft and the label up, but if you mount yours differently now is the time to make the appropriate selection.
Now hook up your plane being sure to put the left elevon servo on the AIL channel. Put the right elevon servo on the ELV channel and hook the ESC to the Throttle pins. You should have the first three rows of pins connected and the others blank. Be sure you position the signal wire properly. The orientation for the S8R is the other way round (go figure). You'll see a little diagram on the side of the RX.
Now test the throw direction. Depending on how you mount your servos and control horns, the throws will be OK or not. Go to the OUTPUT menu or Mixing menu and reverse the directions as necessary. You may have to do nothing, one servo, or perhaps both.
Once you have the controls going in the right direction, check the stabilization reaction.
You should have set stabilization on one of the three position switches so that you can select OFF, Stabilization On, or Wings Level Mode.
Start with the stabilization off and wiggle the airplane if you've mounted your receiver or just the receiver if it's not yet mounted. Nothing should happen. Don't forget to mount your RX in the proper orientation and firmly held down with Velcro or double sided tape. Otherwise, the giro won't work properly.
Now select stabilization on and you should see the controls react opposite from the way you move the receiver; i.e. if you jerk the nose up, the elevators should produce a brief nose down reaction. It may be hard to see. Turn the stabilization gain up if necessary. You should have the gain control assigned to one of the rotary dials. Check the Internet for details.
Select Wings Level mode, tilt the airplane, and you should see the elevons (or elevator and ailerons for conventional aircraft) react significantly to bring the wings and nose level. As you tilt the plane back toward level you'll see the controls slowly return to an in trim position.
It's quite possible for the reaction to be reversed for one or both servos. If so, and if the regular control sticks are working in the proper direction, go back to the Lua script and inverse the reactions using the Lua script. Don't reverse the stabilization reactions by using the output or mixing menu. Use the Lua script for inverting the stabilization reactions and use the output or mixing menu for the regular control sticks.
Double check to be SURE everything is going the right direction. If your controls are reversed or if your stabilization reactions are reversed you WILL crash on your maiden flight.
Finally, tell your receiver how you want your aircraft to fly in Wings Level mode. Set the plane on a table with the wings level and the nose slightly up so that it will fly level or in a very slight climb when you invoke the wings level mode. This is the suggested set up method. You tell your RX about this position by having the TX and RX on and bound. Then you push the little button on the reciever and wait for a few seconds. You'll hear some beeps and the control surfaces will wiggle a couple of times. After than, move your ELV and AIL sticks to their full extend and the rudder as well for a conventional aircraft. CAREFUL: Do NOT bump the throttle because at this point you must likely have a prop installed. Finally disconnect the battery and the RX will remember what it thinks is the wings level flying attitude. You can also invoke this self check by setting up channel 12 on a three position switch and rapidly moving it back and forth through the mid position several times. The Internet has details.
Or, after you gain a bit of experience, you can do what I do. I set up my conventional planes as above. but I position my hand launch planes on a table so that the wings are level and the nose is way up, around 25 degrees or so when I push the button on the RX so it can learn the attitude for wings level. Then I launch them with the wings level mode active. No matter how poor my hand toss is, the plane immediately goes to wings level and sets up a significant climb. I can take my time getting my thumbs on the sticks. After the plane gains some altitude, I turn off the Wings Level mode and revert to normal stabilization on mode which is my normal flying mode. Keep in mind that the first method will work well for beginning flyers who can benefit from learning to fly with the wings level mode on all the time. If in doubt, let go of everything and you'll be OK.
But soon a beginner will transition to normal stabilization mode which is essentially like old school flying with a little help for gusty wind conditions. The gain control can give you as much or as little stabilization augmentation as you wish.
Since I no longer use wings level mode for ordinary flying, it is nice to set up the wings level mode for a significant climb right after releasing a hand launch. It's not so useful for normal flying when I set it up this way, but it is wonderful for hand launching. Still, if I lose visual orientation, the emergency use of wings level mode remains valuable, realizing that the plane will fly wings level and climbing while I get reoriented.
Dig around the Internet for details on how to perform the steps I've outlined. Do NOT skip any steps. Soon you will be enjoying your FrSky gear which I think offers the best bang for the buck plus it can do lots of stuff the more expensive gear can't. Just be sure to triple check the control throw direction both for normal flying and stabilization mode reaction.
