FuriBee F36 (1 min 21 sec)

FuriBee F36
FeeBay $18 Australian

Wow , came this morning .. For the price of a couple of burgers and fries you get a rather remarkable little quad .
Obviously what lets it down is the toy Tx . And at this time the F36 is not supported by Multi protocol modules ( That I know of )

Toy Tx : Is some what vague , almost 50% of the control input does nothing . It takes about 30 seconds to adjust to how much stick throw is needed to make the F36 move . Ok fair enough , what do you want for $18 ozzi bananas .
I think FuriBee should make a Bind and fly version , maybe DSM2 or something . ( The FuriBee F36 would be insane on a decent Tx )

F36 : This little quad does not lack power .. I was simply amazed at how well it recovered as I played with the Toy Tx .. As it headed for the ceiling I cut power and it obviously dropped like a stone .. After about a 1 meter drop I applied power and the F36 stopped falling .. Not only that but it actually had some punch .

A micro quad for $18 that has power to spare (?) , damn it to heck this quad needs a decent Tx .. ( an absolute waste on the Toy Tx )
The Quad is done serious dis service by the included Tx ...
The FuriBee should be Bind and Fly , it's just to good to be a kids toy .

So it the manufacturer should read this - you *(&^%%*&(*&_)*& why did you go with your own protocol ? I guess you guys just wanted to limit your market share ( is...Continue Reading

Is it a dogs breakfast ?
With a front moving in , it will be a while before I find out ..
But its done !

Flying weight is about 33.5 grams

v911 wing ( Mini Micro ) (0 min 29 sec)

Everything is hot glued ...

V911 Micro Wing ( Thats its name now ) is bound to my Flysky 9X .. ( Simply allows me to configure the servos as needed )
In this regard the i10 is not that flash ..

Still needs the controls cut out and set up , and vertical fins ..
But I need a rest ( or actually my back does )

So hopefully be done in a day or two ( I hope ) , got a fair bit done today ..

So I havent gone for a huge sweep , motor and V911 board are ready to be hot glued in place ..

Then I will see about adding some carbon rods to stiffen / strengthen the center section ..

Cut the control surfaces , and connect them up ..
Then make some vertical fins , add a battery and CG test ..

iRangeX IRX4 Multi Protocol Module ... A user perspective !
Sent by banggood.com for review

I think I saw the first multi protocol module about a year or so ago and thought , what a fantastic idea . I actually purchased my 9XR pro with the original module in mind . Reading the add at banggood it said that there was a V2 in the works so I thought I would wait . It's about 6 months since I decided to wait and I am sort of glad I did . Every now and again I like to window shop ( and spend some $$ ) so while looking at batteries on BG I spied the iRangeX IRX4 which did appear to be the updated multi protocol module , a very hasty Email enquiry confirmed my suspicions and a IRX4 was on its way .

 OpenTx 2.2.0 RC18 N371

I have to talk about the firmware . You need openTx 2.2 to suport the multi protocol module . openTx is a firmware development for Taranis ( FrSky ) transmitters . Now the claim is that you can install openTx on all 9x variant transmitters ( Taranis 9x - Flysky 9x - Turnigy 9x / XR / XR pro ) . There is little choice in this regard , you need firmware that will support the multi protocol module . I was able to get all the software / firmware and install openTx on my 9XR pro transmitter . I installed the software AETR and for some reason it was RETA , but you can re assign channels in the Tx ( Which I did ) . Unfortunately for me the trims remained with the sticks , so adjusting trim on Aileron actually...Continue Reading

Wow , this module ( Rather the software / firmware that allows its use ) is keeping me busy ..

Ok I was able to also bind my Eachine H8 mini ( This is so much quad )

iRangeX IRX4 bound to Eachine H8 Mini (1 min 3 sec)

Video gives the protocols needed ..

So I am to date not that impressed by openTX 2.2 ..
I removed all software / files , downloaded everything a-fresh and re-installed openTX to my 9XR pro ..
This time I installed the software ( Not AETR ) RETA , and it looks to be functioning in the Tx as AETR , even though the menu shows something else ( ?? ) oh yeah , I dare say some more work might be needed .. Either that or you need a Taranis to run openTX reasonably reliably ...

So I moved the iRange IRX4 module to my 9XR equipped with the latest er9x firmware .
Then proceeded to bind my WL Toys 959 quad .

Playing with the iRangeX IRX4 multi protocol module meant installing openTX 2.2 firmware to my 9XR pro ..

"AND" I have to honestly say , openTX 2.2 Bites hard ..
Seriously , can you trust this open source firmware = No you can't ( so is my opinion ) ...
I have found several issues , and one issue makes the firmware some what NQR ( not quite right )
I post this as moments ago openTX crashed and burned , wiping all settings etc .

A) Installing openTX AETR does not mean you get AETR because for me Aileron and rudder were switched ..
So I got RETA , even though the firmware was installed AETR ( ????????? )
Now you assign function to channels , but this then leaves the trim tabs as they were , so if you need to trim on the fly it could be problematic ...
Possible solution is to install the firmware RETA , so if Rudder and Aileron revers it will then be AETR ..
B) After re flashing openTX after it crashed , it began to freeze on start up .. Removing the SD card seems to be the cure , so also looks like some sort of SD card issue as well ...

So what does this mean ?
It simply means that openTX is not entirely stable , and if its not stable , then how safe is it to use ?

iRange IRX4 bound to Walkera QR W100s (1 min 0 sec)

iRange IRX4 @ BG

Wow ! The bind was painless ...
( Turnigy 9XR pro / openTx 2.2 )

It took me something like 20 attempts to bind the W100s to my Devo 7e ..
Binding the W100s to the IRX4 took all of one attempt .

Let me describe the bind process , seems to be some what reliable !

In the first menu ( setup )
go to multiprotocol ( where you chose your module )
Just chose Devo for the protocol ( for the W100s )

There is a option for Bind ( BND ) in the menu under multiprotocol ..

I like to fire up the Tx , and highlight the BND ( bind ) function ready for activation ( menu key )
Then plug the battery into the model , which will go into bind mode ...
As soon as this happens I start the bind process in the Tx ...
This method is as yet to fail to bind ..

See picture for throttle cut ..

Under special functions ...
Pick a empty slot , toggle your throttle cut ..
And just do what is shown in the picture ...
Now you can play ...

iRange IRX4 Multi protocol module from Banggood (3 min 36 sec)

Came in the mail today iRange IRX4 Multi Protocol Module from Banggood

To get my 9XR pro ready for this Module I installed openTx 2.2 ...

How good is this firmware (?) ... Give me some time , I am finding a few things that seem to be NQR .. So far I have been able to work around them .

I have bound ( this afternoon ) to date ( a few hours ) a Orange Rx ( DSM2 ) as well another DSM2 Rx ( I don't remember which one ) , as well a Flysky FS-R6B 6 ch Rx that is in my Rainbow 2 wing , and a WL Toys 959 Quad .
( 9XR pro - openTx 2.2 Firmware )

Now I would also like to try my 9XR with er9x Firmware , as it looks to support a Multi protocol module as well ..
I don't know that it will support this one ?
But hey !

Still some playing needed , lots and lots of playing with the iRange IRX4 ( And openTx )
I will do a review , but first I need to educate myself with the IRX4 and openTx .. ( Both go hand in hand )
With is better ? openTx or er9x ?
Which is easier to use , lets not forget - does er9x work with the module ?

So many questions needing answers !

rainbow2 cg test (0 min 45 sec)

Now I read some one say they were flying with a CG 165mm from the front of the wing ..
So my CG was set bang on 165mm and quite clearly that makes the wing nose heavy .
I might try 175mm and see if its better ..

The wing definitely has a tendency to push the nose down very quickly as speed drops ...
I will also have to update my previous post ..

I am super excited by this one ... Really looking forward to getting my hands on one ..

I have receivers and models to try and bind to , should be very interesting . Been waiting for something like this for some time ..
Hopefully be able to lighten the Tx load ( own fewer transmitters and maybe buy more mini / micro's )

No its not dead ! , simply going to analyze the build now that the wing is done ( Built )
If you had all the parts and gear and equipment needed to assemble this wing , and you thought about it a little , I don't see why it could not be built in about an hour .. Honestly for experienced builders ! This is bush league !

For Noobs to RC ! The lack of instructions is some what disturbing .. But not a deal breaker .
This wing is easy enough build from pictures , and the hardest part would be the fuse/pod .. ( Some planning and thought required here - just a little )

The sticky wicket is the elevator/aileron , the skin tension is huge on my wing .. I did fold mine back like 180 deg onto themselves to try and soften / stretch the foam and it did that .. ( They were much easier to move ) But when I put the carbon rods in place ( Elevator horns ) , the tension was simply too much .
So I got out the hobby knife and cut through 50% of the material joining the ele/ailerons .. Now the carbon rod was no longer flexing .. But there was no way the servos could do 100% movement .. The skin tension was too high for that .. So limiting the servos to 50% throw is a solution for now ..

Rainbow2 Post Build (4 min 15 sec)

What would I change ?

Obviously laying the servos down on their sides ( I did that )
Some instruction , for Noobs the pictures may not be enough ..
The Elevator/Ailerons , I would hinge them ...
Something on the bottom of the wing to grip/hold...Continue Reading

We are getting close to the finish line now ...

One only has to decide where to put stuff , and then glue and screw ..
I put my ESC on top , simply to leave plenty of space for a battery ( I ended up using 1500mAh 2s )
But I want the option of my longer 2200mAh 2s ..

I used double sided tape for the 6ch Rx , as well the ESC ( but the ESC was given some hot glue )
The fuse / pod was 5 minute epoxied + hot glued ...

The servos were super glued ( very lightly ) as they were already a tight fit .

Once I got the control horns in place I realized the Ailerons were too tight for the Servos and associated hardware ..
I had flexed these back onto themselves , but the surface tension of the foam was just too much ..

Rainbow2 Skin tension (1 min 35 sec)

You can watch the vid if you like ...

What I did was take a hobby knife and cut through about 50% of the join .. Now the servos can actually move the ailerons ..
The surface tension is still high , so I limited the servos to 50% throw .. I will post a POST build video ..
This seems to be a working solution ( for now )
You may wish to cut out the Ailerons and use hinges , this would make life easier on the servos ..
Something to be aware off if buying the Rainbow2 ( Actually any foam model )

This really has been a easy build ..
If you had a decent work space , all the components you needed .
Some foam safe cyno , there is no reason this wing could not be completed in a Morning and flown in the afternoon ...

CG /
Somewhere around 165mm to 170mm from the front edge ... I aimed @ 165mm and then take it from there ..
UPDATE - 165mm = Nose heavy , 170mm or 175mm might be a better place to start ..
I have plenty of wiggle room with the battery ...

Just a quick vid to update the build so far ...

The ply mount is way small for a 2212 and its alloy mount ...
So I had to remove the mount and screw the 2212 directly to the ply mount ( see pictures )

I put the servos in sideways , flush with the surface of the wing ...

I also ran the servo wires through the slot cut for them .

A) The servo wire slot is a very fine cut , you may wish to use a BBQ skewer to open it up so that the wires are easily pushed in .
B) Dont glue anything !

The engine pod / fuselage ....

There literally are no instructions regarding its instillation what so ever ...

A) Work out where you want to cut the slots for the fuse / pod
B) Make sure your motor prop has clearance
C) Try an not mount it too far forward
D) It really is hard to get it wrong
E) I put the rear fuse ( mount legs ?) about 5mm inboard from the servo wire slot ... And tried very hard to keep everything central .. ( I used calipers )
When having done the rear slots , I then measured / marked / and cut the central slots , fitted the fuse / pod and then marked / measured / cut the forward slots ..

Did it slowly and carefully ...
Also used the BBQ skewer to open up the slots so that the Ply legs would insert without force ...

I haven't glued anything in place yet .. I will pop in the ESC / Receiver / and battery and see how much room I have , locate the goodies , and then see about the CG .. Once everything looks good I will glue things in place ...

Ok , did some prop testing today ...

I am going to shoe horn in my 2212 2200kv motor ..
This motor has a Max Amp ratting of 12A and a continuous max ratting of 10A
I only plan on running 2s and

I only have a bunch of 6 inch Dia Props so decided to just bite the bullet and test them ..

The most thrust seemed to come from the Gemfan 6x4 Bull Nose , unfortunately on 2s it was pulling some 15 amp ..
But it had enough thrust to pull my test block of wood out of my hand ..

Most of the other props 6x4 and 6x4.5 were pulling around 10A with good thrust ...
The best prop for me was a 6x4 that was pulling 8 Amp and producing good thrust .. I dont know the brand .. ( I will include a picture soon )

So that was my morning , sorting out the motor / prop combo ... ( I did try a 6x3 Gemfan , @ some 5A the thrust was adequate ) I will have to see about some 7 inch props ( maybe a 7x3 )

Right now I am sorting out my servo install ... ( 9g )
If you install your servos vertical , dont forget to cut a servo lead slot ..
I decided to do some cutting and lay my servos down on their sides .. ( See pictures )

There is a slot in the wing for the servo lead running to the fuse , but it needs to be widened .
So thats today ..
Play with the motor and install servos ...
I really am trying to do this right ! So I am not in a particular hurry ..
Oh and don't forget , glue the servos in last , after you have connected your radio and done some basic trims ...

So far this has been some what bush league , seriously . I have not encountered any serious problems or assembly functions requiring anything close to advanced skills or techniques ... One of these wings could be a great first model ... And by no means cost prohibitive ..

Up next will be my motor install and fuse install

Rainbow2 part 2 (4 min 23 sec)

Well I stuffed up , I don't know what happened ?
Instead of turning the camera on , I was turning the camera off ! ( My bad )
product page DW Rainbow2 Flying wing

So here we go !

The wing is 3 piece , and has some 6 carbon spars that need to be glued in place ( That's what I did today ) Video shows me gluing in a carbon spar .
I did want to document the entire build but stuffed up ..

First thing I did was hot glue the wings together .. ( Actually hot glue makes for an excellent bond )
I got the left side perfect , but got the alignment wrong on the right by about 1.5mm ( Spar cuts )
Seriously , hot glue holds very tight - I had to cut the panel off with a knife and re - hot glue !

2nd times a charm , the wing is fantastic - really straight !

Next came gluing in the spars , I used 5 minute epoxy for this ..
The epoxy did dissolve some of the print of the wings ( Cheap epoxy ) ...

Now the resulting wing is very straight , the assembly was extremely simple ( very noob friendly process ) and I can see how instructions would only need to be very basic ( The included instructions dont really cover wing assembly at all ) , but it is very much bush league ( assembling the wing )

1) Put the pieces you want to glue on the table , test fit ( push them together ) check alignment !
2) Apply hot glue to one side , then push the the parts together making sure to align correctly
3) Carefully check to see if you...Continue Reading

DW Rainbow 2 Flying Wing Part 1 (1 min 44 sec)

DW Rainbow2 1000mm RC Wing

Boss , the plane , the plane ( or wing in this case ) , it's here !
First I would like to thank Banggood for sending me the wing to Review ( cough cough - Play with ) .. https://goo.gl/GeSDBO = Product link !

I am really taking to these wings , I have just completed my Spirit 600mm ( Purchased from Banggood ) and done some glide tests ( chuck tests ) . I like these for several reasons
1. Strength - Oh they be strong !
2. Simplicity - Very easy to assemble ( I wont say build )
3. The $$ investment is low
4. Value for money .. For some , it's just about flying , not what you fly or how much $$ is up in the air . And in this regard ( putting a smile on your dial for as little as possible ) the wings are an excellent way to go .

For the last 5 or so years I have been flying helicopters and quads , I haven't flown a plank ( Plane or wing or anything with a wing ) for some 20 years .
Yeah , that means I am as rusty as a 1950's Buick dumped in the back field for half a decade .. ( Ok , maybe not that rusty )
But consider me noob at the sticks of a wing ..
Anyhow , I will do this like a build log ..
The Spirit 600mm was easy to put together , so I dont expect the Rainbow 2 to be particularly challenging ( build wise ) , and being a 1 meter wing I hope it will be some what bush league to fly ( slowly - not @ 100mph ) , nice and slowly ...

Anyhow , I will...Continue Reading
