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

3D Printed Plane Under Construction for potential Destruction

3D Printed Plane – Placeholder as this comes together:

Here is the start:

Bad Piece – was able to use GG and CC to repair

First two pieces together

Starting the Wings (Notice the Carbon Spar – 4mm )

 

Wings to Fuze – Face of parts not exactly parallel, used small amount of GG as filler, and also GG inside spars to help hold.

The smallest EDF I have is 60mm, as you can see, it needs a 50mm

 

Found the proper screws for the EDF Cover.

 

Looking Good!

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.

Combat Wing Build Log

Have been having so much fun with the gremlins & wings, as fun to fly no stress scratchbuilds, that its time to build wings for Combat.

First they have to be Cheap to make, and take little time to build since the expectation is they will be crashed in short order!

I started looking at A. Newtons site, where he hot cuts wings based on the FT mini wing plan. Well, the LAR principle kicked in as I started copying his template, and it just did not:
Look About Right!

I wanted a wing with the CG easier to meet, based on some ZRM motors I have from an old quad, a 3s 1300 pack and enough reinforcement to keep these wings together for a while….

My template,  when the LAR principle kicked in, has a wing span of 735mm, Root chord of 315, Tip chord of 163 and a sweep of 234mm. All this translates to a calculated CG of 145mm.

More to come as I add motors, corroplast fins, etc!

Finished – coroplast winglets, 2300kv swinging 6×4 prop with blheli matched esc’s.

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:

Scratchbuilt FunJet

After totally destroying a multiplex funjet, I used what was left of it to take measurements.

The hardest part of this build was creating and hot cutting the wings.  Each wing is built by using symmetrical airfoils that scale down in both cord and thickness as they move toward the wing tip.

Once glued, a carbon spar was laid in for strength. The fuse is simple, just 2″ foam block hot wired to shape. As this foam will not take an impact,  I heated a steel rod, and drove it perfectly center down the length of the fuse. This permitted the insertion of a square carbon fiber rod, that will hopefully keep the fuse from breaking on a nose impact.

Power system is currently a Greyson super megajet motor, 6×4 prop and a 40 amp esc.

Maiden will be interesting!

WTF Returns….

Since the destruction of planes seems to have become common these last few trips to the field, I have an abundance of left over pieces from smashed planes….

The three contraptions below consist of parts from the following planes I have crashed….
Corsair
Gremlin
Storch
Guinea
Wingnetic
Ugly Stick
Slow Stick

Will they Fly????

Check out the Video of these:

Mini Gremlin #2

Since both the full size and mini Gremlins fly like a dream, I could not leave well enough alone and decided to build a very slightly different one.

For this one, I increased the wing span to 34″, and used symmetrical airfoils from the corsair build, hot cutting them to have a slight upturn at the TE of the outside airfoil.  Supposedly this helps a wing design offset the natural tendency to track downward….
This slight upturn is only 1/2″ and is difficult to see from the photos, but does give the span of the wing a slightly different angle tip to tip.

And of course, speed is always an issue! The earlier mini gremlin uses a 1400kv motor, and while quite respectable, I’m curious what kind of control I would have with a faster gremlin.
So, this build has a 2200kv motor, swinging a 7×5 prop…..
