FrSky S6R RX – Wing Setup How To

This page is in response to two comments on my youtube channel:
peteroake channel

Eric/Warren, I hope this is some help to you.

Ill start by saying I am NOT an expert, its just that I have played around with this till I finally got it working the way I expected it to. Do I know if this is the right way – No!       hahahah
But I will say All of my Wings are flying Perfectly using this setup.

My Taranis has the following switch design for using the S6R:
SF = Throttle Cut
SA= Low, Med, High Rates
SB= Up is Stabilize Mode, Middle is OFF, and Down is Auto Level
S1= Pot to control intensity of Stabilize mode (when SB is in up position)

My radio is running Opentx 2.9 the last stable version before the release of Ver3.
I use OpenTx Companion 2.1 and to make things easier here is a link to a compressed copy of my S6R only Wings. You can open this beside your own radio models inside Companion and I believe just drag any one of my models to your radio.
Link: S6R Wings Companion File

This file, if you open any of the models, contains the following info. In case you cant add one of my models to your radio, just create a new and match every page shown here:

And for the mostImportant Part, the Config File for the RX itself. Here are screenshots of the actual settings for the wing at the top of this page:

 

Some Final Notes:

When in Auto Level, I set SA DOWN – this gives me Max Rates and makes it very easy to control the wing, even with AutoLevel active. Typically, for me, S1 is at about 20%, this seems to be enough for even moderate wind.
You MUST do the final setup of the RX – where you power the model, wait till its initialized, they Briefly press the bind button and MOVE ALL STICKS to their extents. (only needs to be done once)
If you don’t, your servo throw will be too small to successfully control the model.

If you look at my youtube channel at the recent video of the Wing Jet from World models, it is also using this exact setup. And if I did not crash that thing, this must be a good setup! hahahah

Wing Addiction

For the last few weeks I have been totally engrossed with Flying Wings, and have built at least a dozen.

I have been trying different airfoils, from clarkY to fully symmetrical, and have decided the most stable is the ‘clark’ series.

Have tried different designs, sizes and motor changes, all the way up to an 11″ prop on a 800mm wing.  As I like fast wings, the ideal setup for me is a 2200kv, with a 3s 2200 Lipo – a bit heavy for fast elevation changes, but overall fun if you don’t mind crashing into the ground once a day!

Here is a picture of my latest design – hot cut clarkZ airfoil, from dense thick foam, covered in 5mm laminate them wing tape for color. Driven by a 2200 kv & a 6×4 prop, this is my favorite over all design.

As well, the Videos linked below contain some shots of other wings I have built and crashed.

The Pitt-Tastic….

Ok, so I started with the plans from an old balsa FSW called the spintastic…. It was forward swept with a profile fuse and a rudder. This is an exceptionally odd design so thought I would try it.

However, once I had the wing built I noticed an old HK pitts biplane that I had badly smashed many months ago…

It had a partly intact fuse, no wings, busted elevator, and crushed motor shaft, and really should have just been scrapped.

Being over tired, using this pitts with the spintastic wing seemed like an awesome idea!

Sooo, I cut the fuse apart to take the FSW at midpoint, repaired the motor mount, elevator etc, and glued it all together!

I really need to stop building planes late at night!

Building the wing from 2″ pink insulation:

Gluing it all into one and using packing tape rather than laminate:

LAR Plank

Continuing with the flat plank style, here is a design with a fully symmetrical airfoil, and the LE cut at each corner to prevent tip stall.

Apparently the winglets are not required with the this cut, however, decided to play it safe.

Running an 1100kv motor and an 11″ prop, this design flies like a dream.

*Update – got caught in some wind, drove the plank into a building… this is No More!

LAR #4 Slo Wing

The Krazie Wing from an earlier build remains an interest, and since I had an armin style wing, with a slight dihedral, thought it may be worth the time to see if the krazie wing principle could transfer to this type of airfoil.

Powered by a sunnysky 750 spinning a 13×8 prop, it seem to have enough thrust to reach the moon! I’m using CG from the previous wing, however this feels extremely nose heavy. Will see if survives its first test flight!

LAR #3 Extended Wing

Building on the previous wing, I added an 9″ center section to permit more equipment mounting area, and to widen the stance of the wing to see if more stability is created. CG for maiden is via the online cg calculator for wings.

I’ve powered this with a blue wonder 1750kv, swinging a fairly mild 7″ prop. It appears to have enough gumption to be able to fly, but I’m not expecting a speed demon. Should be fairly docile.

The wing is hot wire cut out of white styro, with a clarkX airfoil (scaled by 70% for end). Appears very light and cg when using a 3s-850 battery is difficult to set, thus I added the fuse/canopy to give me that few extra mm’s to meet the CG I think it should be at.

SkyRay

Closely based on the StingRay as designed by dz1sfb, this simple wing is made from a mix of grey depron & MPF, covered with laminating material on the lower surface. (34″ wingspan)

The original has a lower fuse out of layers of foam, I just hot cut some 2″ foam as a solid block, eyeballing the motor angle.

Since I want to see if this design actually flys well, I used a very small 1700kv Blue Wonder stick type motor, with an 8×4 very cheap prop held on a prop saver.

CG is exceptionally odd and important for a wing so I read, so spent some time getting this right. (I Hope!) Ideally it should be powered by a 3s, but since I really want to keep this light to see if it can survive a maiden, I opted for a 2s1300.

There was too much wind to fly this morn, so all in, the complete build of this wing including waiting for the GG glue to dry is only about 4 hours total.
