Control Surfaces &

Mini Surfer 800 from Banggood.com (1 min 47 sec)



The short of it is , the Mini Surfer 800 is ready to play the CG game ! ( Check out the video )

Vertical fin and horizontal stabiliser ( Rud / Ele )
I glued these in place with foam safe cyno ..

Controls /

Ailerons - you need to cut them free as they are ever so slightly moulded in place . Also they are some what stiff , so you may want to take a knife and cut the hinge line 30% to 50% to release some tension .
Elevator - same as above ..

Control horns .. Bush league .. They be the press together type , some glue wont hurt .
Control rods - again bush league .. ( See pictures )

With everything connected

Just check direction of travel - I had to reverse everything .
With my set up Ch4 is another Aileron Ch .. This means I can do flaperon at a later date ..

Ch1 - Aileron
Ch2 - Elevator
Ch3 - Throttle
Ch4 - Aileron

As mentioned this will be a 2s Bird . Thrust is nice and almost 1:1 with a 2s 850mAh battery ..
CG is too far back , so most likely will need a larger ( heavier ) battery .
I only have the 5x3x3 props , though I did order 2 pair of 5x4.5x3 .. ( Who knows when they will get here ? )
So the potential is there for more thrust when the new props get here ..

I did run the Mini 800 on the ground and it is accelerating ( in the back yard ) , so I dare say I wont be lacking power for...Continue Reading

Installing the Receiver

I am using a small FS2A Rx from banggood , so far these have proven to be cheap and reliable for me .
The Rx was put on the foam protrusion that is the forward wing lock into the fuselage . I wanted to keep everything together as much as possible for the insertion and removal process of the battery . So everything has to be as clean as possible .
There is only one wire to contend with now and that is for the elevator servo and it is a very long wire . ( See pictures ) This seemed to be the logical way of
doing things ..

ESC

The MR RC ESC simply did not work . I dont know what happened but the ESC and Rx simply just threw a WOBBLY ! Connecting a battery and things kind of went haywire .. So I tried another ESC and everything was fine ( ?? ) Sharp eyes may pick up that I have installed another 12A ESC .
Everything looks to be working , the install is relatively clean and clutter free offering easy access for the battery .

The next thing I do is install the tail surfaces and connect the control surfaces . After which I can worry about the battery and CG .

Part 4 / Ready to play the CG game

Motor ESC install

I had some alternative ESC's to chose from in the 10A to 12A range ..
Chosen was the MR RC 12A ESC , since it already had a connector on it .
Yes , the plan is to run a 2s battery with the 5x3x3 prop ..

With the ESC soldered up , I did a quick current check and the combo pulled some 5.5 amp ..

A) Motor pod .. I was very easily able to open it up .. This allowed me to tighten the motor mount screws .
I then proceeded to hotglue the motor mount into the pod and hot glue the pod shut .

B) Since I was playing with the hot glue , I hot glued the pod onto the wing ..
No issues here , and the wing fits to the fuse just fine .

C) The 12A ESC was zip tied to the wing and the cables routed through the hole to the inside of the wing .
The ESC should get plenty of air where it is . Seems to be a very neat install .

D) At this time I do not plan to run 3s , just in case anyone was wondering .

E) Next I need to watch some TV , give my back a rest .. Then I will solder up the Rx ...
This one from BG , simply my Fav 4ch Rx right now ...

Part 3 - Install the Rx ...Continue Reading

Mini Surfer 800 sent for review by Banggood.com

AF Link - https://www.banggood.com/custlink/mDDGrhd0ma ... to product page

The opening bout weigh in

I thought it might be interesting to weight the mini surfer to see what sort of weights we are dealing with .

Fuselage = 50.4 grams
Tail ( Ele / Rud ) = 12 grams
Wing = 82 grams
Motor Pod ( Motor / ESC / POD ) = 71.4 grams

All those were individually weighed for a total off = 215.8 grams
Now if I assemble the fuse / wing / tail I get 144 grams and adding the pod returns some 212.5 grams ...
Yeah , that's a few grams Variance there .

I am really impressed with the weigh in less the motor / pod / esc .... Hmmmm , 71.4 grams is a little weighty ..
Even the wing @ 82 grams is a little sturdy ..

My first impressions are that the Mini 800 is well moulded and all the parts fit well together .
I dont think I can bring it in under 250 grams flying weight ..
There would be some serious dieting required to meet the new Libnazi RC rules that will be shoved down Australians throat's shortly .
Oh , for all those Australians , don't forget NOT to vote for the people that want to kill your hobby ! ( )

The Mini 800 just arrived , and the first thing I am going to do is run up the motor / ESC / prop combo as it came in the kit to see what sort of power / current / thrust we are looking at ...



UPDATE !

3s / 5x5 prop ( included ) / 15.7 Amp ( peak ) recorded .. Average is in...Continue Reading

ELF DLG @ the sink hole (22 min 20 sec)


Sink Hole = Local Park ...

Most of the air seems to go down , not much air going up ..
It's some what rare to catch air that can lift a DLG ...
Lots of turbulence though , if you like that sort of thing .. Probably from the trees ...
But since I put the screw into the nose of the ELF to hold the Canopy / pod / nose cone in place , I thought it best to actually test it under field conditions .

The screw worked perfectly ! , I'm happy to report .
Posted by old4570 | Apr 11, 2019 @ 09:50 AM | 681 Views




I really dislike using tape to hold the canopy ( pod ) in place on the Elf DLG ...
So for a while I have thought about screwing the Elf
To hold the canopy in place ...

There is a hole in the front of the canopy ( pod ) , and I thought if I put a screw into the front part of the boom ... It could act like some sort of fastener to hold the canopy in place without the needed tape ..
And it looks to work ...

Part 2 : ( Theory )

So my idea was to have a screw with a small enough head ( 3.3mm ) so I can slip the Canopy / Pod in place without actually removing the screw . Who the heck want's to drag tools to the park , and possibly lose the screw in the grass ? That would be super annoying !
So now the screw head has just enough tension on the face of the edge of the opening to hold the canopy / pod in place .. And just a little bit of force is required to pull the canopy / pod off to install or remove the battery .
Should the plastic wear , I can put in a new screw with a slightly larger head ..

Is there anything better than a bushleague mod ?
Maybe one that cost's only one dollar ?

I got myself one of those USB 1s chargers off Ebay for all of one Ozzi Banana ( $1 )
Then I soldered some connectors for batteries I use a lot ..

Description from Ebay add ...

5v Micro USB input OR 5v Power source (the power input solder points are exposed)
Red light indicates charging and Green light indicates fully charged
The input voltage must be rated at 5V
Maximum charging current: 1000 mA or 1A
Charge cut-off voltage: 4.2 V + / - 1%
The battery overcharge protection voltage: 2.5 V
Battery over-current protection current: 3 A
Size:2.6 x 1.7 cm


Now it's important to remember that this little charger is supposedly capable of charging @ 1A
Thats one amp !

But , the important thing to remember is , this is very much dependent on the power supply
So if you have a USB power supply that delivers lower current ?
I have one that does low current , which makes this bushleague mod very user friendly for charging small batteries ...
Max charge current is around 240mAh
And importantly , the charger actually stops charging ...
The terminating Voltage ( Of the battery ) was 4.19v , which is simply superb ...
If you had a variable current USB power supply , you could have a very powerful 1s battery charging solution ...

The old now V911 heli control board is getting hard to find and some what premium priced ..
So I felt the need to find an alternative ..

There is still the V949 control boards , but with the release of the new V911s Helicopter !
I thought I might search out a control board and see if it can be used for other applications .
Being a fan of the V911 boards , they will be missed for being a cost effective way of controlling RC projects ..

The V911s board is not a very good option at all .. Much cheaper to buy a 4ch micro Rx and some cheap servos ..
Especially since the FS2A one from Banggood runs so well on a 1s battery ..

Either way , I thought I would try out the new V911s board . ( For my curiosity )

Minimum RC Piper J3 (3 min 16 sec)


Here is some flight video ...
The J3 really can fly well when the correct CG is achieved .

I was how ever having issue with the V911 flight board , where by the servos would stop working for some reason ( ?????????????????????????? )
Don't ask me , everything was fine , then crash !

There just was no servo response .. I could cut the throttle just fine , but the servos .
Cant blame the J3 for the flight board issues !

Anyways , I unsoldered the antenna and replaced it with something much longer ..
Will see what happens ..

Aside from the servo issues , the J3 did impress ...

J3 @ Banggood

Watch the video , and see what you think ...


Sorry - Forgot !
I was flying @ 30% to 50% Throttle ....
So there is more power available ..

Went to the park , took the UMX Whipit as it has not flown in quite a while ..

UMX Whipit at the park (7 min 59 sec)


What can I say , it was cool and overcast , so the park was dead ! ( No thermal activity )
The whip behaved itself ok , just a little trimming for the conditions .
I really struggled for hang time though ...
What was it with 24 seconds ?
I got in one 41 second toss , but nothing close to a minute ..
Some times the park felt a little like a sink hole !


Minimum RC J3

Took it out to the street this morning ...
It was really hanging it's beehive .. And tip stalling like a champ .
Hmmm , I could only wonder if the CG was too far back .
That wing is a little like a parachute , so it might have been ballooning .
So I move the battery further forward ( Quite a bit )
VIOLA ! - It flies , right into a tree !
But no , it actually flew like a RC plane is supposed to fly ( yeah , right into a tree )
So it flies .. I just need more space ..

I will try and get some video of the J3 , maybe tomorrow morning ...

The V911 control board has been connected to the motor ..
And then hot glued into the J3 ..

Elevator / Rudder connections made ..

I did some chuck testing with the battery taped to the fuse and ........ I put some Velcro on the belly !
This way I can move the battery for CG ..

It's ready ! Just charging up a battery now ...
It is way too breezy for the J3 outside , so I might do some taxi runs in the hallway ..
It was very calm last night . so maybe a after dark session with the J3 ?

https://www.banggood.com/custlink/KK3GrdJ1Bo - Minimum RC Piper J3 @ Banggood.com

I saw this on banggood.com and thought - how cute is that !
With Oz Wizards becoming crazy %^&^&#$^*'s and criminalising RC in Oz , it looks like law abiding citizens need to think smaller if they dont want to be licensed and registered like gun owners for flying model air-planes .

So with crazy Wizards running Oz !

This be a very small J3

Specification
Wingspans : 360mm
Length : 290mm
Weight : 25g
Motor : 720 coreless motor

My plan is to use one of my precious V911 boards to fly the J3 .
So as pictured , is where the stock build ends ... And the V911 conversion starts .

Fuse:
Comprises of 3 pieces of depron glued together
This makes for a light yet relatively stiff sheet fuse .
Only issue I see , is the section for the Rud / Ele is left as a single sheet . This makes the tail somewhat flexible and weak . ( Could be an issue )
Also be sure to alight correctly as the two outer pieces are used to create a slot for gluing the wing into .

Rud / Ele:
The rudder seems fine , but you need to be careful gluing the elevator .. It needs to be located carefully so it does not sit too far forward or to far back .
Also it is best to get your angles correct . the ele does not just sit there while the glue dries , it tended to droop for me .. So I needed something under one ele tip to maintain that 90deg angle with the rudder while the...Continue Reading

Monday Afternoon ..
Cool Overcast ( Dull grey cloudy day ) , but little wind ..

It was almost an ELF'ing day !
So I had to take the Elf to the park ..
This time I used the slightly heavier 260mAh battery to move the CG forward a little ..

Hmmm , my launch settings worked , but I had a problem by where -- When I used the trim tabs to adjust elevator for cruise it would also effect my launch elevator setting ( A lot ) .. I nearly slammed the Elf into the ground because of this ..
Because the Tx was stuffing me around , I deleted the Elevator launch .. Once I did that I was able to play with cruise settings .. And off course this is when the breeze picked up ( obviously ) . Anyhow , I have separated the launch function from the main controls ( Ele / rud ) and put them on empty channels .. So hopefully using the trim tabs wont affect my launch settings .. ( Rather than setting things up as a mix )

Might have to do this for all my DLG's ...


Stuff ...
Another FS2A Rx came ... I do like these ..
Minimum Rc J3 came today ... Will most likely put my V911 control board into it ..
Be interesting ......Continue Reading

Dancing Wings -

Lets start here - I took it out a few mornings ago after doing some tuning in the front yard .
At my CG test site my first Spear Chuck was magnificent . And after that things just got steadily worse until the wing would just GLUD into the ground ..
For some reason , it refused to break , which was nice .

But I was getting frustrated and I was beginning to have daydreams of doing a rain dance on top the wing . The satisfying feeling of venting frustration stomping something into the ground ..

Rather I decided to stick to my plan , and the plan was to DLG the wing if nothing else worked ..

( The docile pussy cat )

Chalk and cheese folks ! The wing becomes a different animal when launched VIA wingtip . No longer a monster LEAD SLED , the wing now launched predictably and consistently - ( It glides - it glides )

Bixler Wing

As seen in the picture , the wing has been joined .. The Bixler HLG has begun ! The wing is 1440mm after trimming and joining . And it really is Floppsy ..
Yes , it will need carbon . It is super flex'y , and the weight is not good , it's going to be a weighty bird . Might be nice on a slope ? or bungee launched .
I will build it ..


Dont know why ?
Got me a small geared motor ..
Maybe ? V911 HLG becomes motorised .... If I can get to the control board .

DVR Link
Tx06 Link

Tx06 was sent for review by Banggood.com
The DVR was purchased from Banggood.com

I have wanted to do something like this for a long time , and the catalyst was Banggood sending me the Eachine Tx06 for review / testing .

Eachine TX06 FPV camera unit :

I dont have video recording FPV goggles , so I cant directly record the video stream ..
What I can tell you is that the Tx06 has the cleanest video transmission I have experienced to date .
It is actually surprisingly good for the price .

I did try to use the Tx06 with two of my micro quads , and whilst they did work well for the tx06 , the batteries in the tiny quads could not sustain the extra current of the Tx06 unit . ( around 280mAh ) .
One gave me 45 seconds of flight , and the E010 I mounted the Tx06 on gave me about 90 seconds of flight .. ( Might need a battery upgrade )
I did finally mount the Tx06 on my old now WL toys 959 quadcopter which uses 1000mAh 1s .. This battery was easily able to handle the Tx06 and still gave around 8 minutes of flight .

Micro DVR :

Since I cant record the video stream , the next best thing would be an affordable DVR ..
The camera and DVR are not plug and play compatible .. Some soldering and splicing is required ...
Power - The DVR requires power , and for this I spliced into the + and - cables running to the Tx06 ..
Video - Well , yes . I spliced into the VIDEO OUT cable for the video signal .
The DVR came with a 3...Continue Reading

Shake N Bake ...
It's all shaking

I was right .. I had to tap into the + and - from the battery as well the video OUT signal wire ..
So it might look complicated with all that wiring , but simply eliminate whats not needed and your talking 3 wires ..

All that's needed is a micro SD card and a 1s battery for power ..
Now apparently the Camera pulls about 280mAh and the DVR about 260mAh ...
So we are talking about , half an Amp region for current draw .. Just got to make sure your battery can handle that .

I will have some video shortly , just need to do some editing ..

DVR
TX06 FPV camera

So what I have here is a very small , FPV camera / video recorder set up that is highly mobile ..
