Wing of choice is the Spirit 600mm from Banggood ..
This will be my 2nd Spirit 600 ..
The first was made more robustly with 9g servos and a larger motor ( 18 something ? )
And a heavy 3ch car Rx
And it needs some weight in the nose to balance things out .. ( Larger battery )

So hopefully the 2nd time around I can do it better :

This time I am going with the 1306 - 4000KV motor ( small - light )
Also a much smaller lighter ESC ( not sure 6A is enough - will see )
Also the servos this time will be 3.7g
And I will be using a Redcon 6ch Rx ( very light )
This will hopefully allow for the use of a small 2s like a 250 -300mAh battery ..
The goal on this build is to go light .. This should allow for much slower flight speed / glide better as well ..
I know , less weight will mean less tolerance to wind ..
But I really want a slow wing ( compact for easy deployment )

Got my hands on some Turnigy LSD NIMH 2550mAh AA batteries ( 8 of them )
For some reason (?) I can't fathom why , I need more rechargeable AA . ( So got me some Turnigy )
So if you did not know , these can be got VIA Hobby King , and are reasonably priced .

So using my Powerex charger I discharged the Turnigy @ 500mAh , returning !

1) 2644mAh
2) 2612mAh
3) 2585mAh
4)2644mAh

I will run a few more cycles through them and see what happens .. 8 batteries will take a while .

Now I do like my quads , especially the small ones ..
And these micro brushless quads seem rather tempting ..
The average price seems to be around $150 USD which is a little steep for me ..
But the Mantis85 seem to be the exception , Fasttech.com has it for $84.07 USD for the Bind and fly ...
The RTF is $113 USD ....

CLICK to check them out

Now with brushed micros being in the same neighborhood price wise , it makes the brushless FPV quad some what tempting ..
Wonder what I am getting for my birthday ?
Stuff I got for myself for xmas rocked ! ( The stuff I purchased )
If my birthday present sux's , I might splash out for the mantis85 ... ( I hear the siren song )

Now besides RC and Photography my other hobby is flashlights .
So I hope you enjoy this review , and do watch the video as this flashlight is a small hand held Sun ! ( Well )
The SupFire M6 was sent for review by Fasttech,com ( They also do competitive prices on RC )

I finally got around to testing it ..

I used a 3s battery to power the board ..
I then tried charging a 2s pack VIA the balance lead .

In the picture you can see I am using a split'er so I can monitor the battery being charged .
And it shows a growing imbalance as the battery is being charged . ( 0.113 volt )
At the start the variance was around 0.04 volt ... with each cell being around 3.8v ..
But as the battery reached 4v per cell the variance grew ..
I stopped the charge when one cell was 4.1v and the other was 4v ..
And then threw the battery on my B6 charger and did a proper balance charge ..

So the question begs ?
Can you balance charge VIA the balance lead ?

Obviously I bound mine to the iRangeX IR8M multi protocol transmitter ( from Banggood.com )

30mA transmit power VS 100mA transmit power ...

The BWhoop was not happy with the IR8M set to 30mA ( for transmit power ) .
Controls were lagy , motors were surging and there were these apparently small brown outs .. ( This is in the same room mind you ) .
At first I was wondering what the heck people were excited about ?
But when I got these quick little brown outs , I thought I better crank the output power ...

@ 100mA the BWhoop is amazing .. Runs like a swiss made watch ..
No more motor surging , no lag on the controls and no brown outs .
Flies amazingly well ( indoors ) ..

We have a lot of wind today .. But I did take the BWhoop outside .. Everything went ok until a gust of wind hit the BWhoop sending it scurrying backwards fully out of control . Suffice to say the BWhoop can not handle wind .

The battery is larger than say what comes with a JJRC H36 or a Eachine E010 .. This = excellent flight time .
Really lively on the controls , I may have to set up rates ( 50 - 75 - 100 )
I also like that there is a plug that is already fitted for a camera ( FPV )

B Whoop B-03 Pro bound to my iRangeX multi protocol module (3 min 15 sec)


Nothing negative to say about the BWhoop B-03 pro ..
I will say , if you like micro quads , you will love the BWhoop ...
Why buy parts to build something , when you can buy it all assembled and ready to go ..
If your going to bind it to a multi protocol Tx or module ( Bayang ) protocol .
I found the bind process fully painless and simple .

BWhoop = Love it and recommend it ...
Oh and to date I have not touched the supplied controller - I went straight to the IR8M ...

https://www.rcgroups.com/forums/show...ol-transmitter ( Part A )

Now at issue is the failure of the gimbals to return to zero ..
And the fault lies entirely with the little sensor pots that fit the gimbals assembly .
In effect they are a poor / or slop fit . ( See first picture )
In a nutshell ! > The cure is to gently crush the shaft that enters the gimbals tube till its a press fit .. ( Crush the widest part , )

The 2nd thing to do is tape the outside of the sensor pot ( See 2nd picture ) to take out the slop @ the outside of the pot ..
Tape both sides ..

Tricky bit is obviously pulling the gimbals apart .

Its all relatively easy till you get to the last sensor .. The gimbals housing has a cover ...
Look for the release tabs .. Turn the gimbals assembly so the stick is down .. Gently press the stick against something and then release the tabs ( push in ) .
With the cover off you can remove the last sensor ......Continue Reading

DLG Control settings ( OpenTx ) 3 position flaps and elevator launch (1 min 11 sec)


So I worked out how to get close to the CG ..
I guess that might have been the easy part .
Next I needed to set up some more advanced control functions ..
Taranis Qx7 - IRX4+ Multi protocol module
DSM2 4ch Rx
Re the DSM2 , it might be faulty .. 1 Ch does not seem to work ( Ch3 ) So might need to order another .

So what I did ( OpenTx )

I wanted to mix functions VIA the transmitter , and the tutorials I found were all for PC programming VIA the companion software ..
So I had to teach myself how to do a 3way switch flaperon ..

The other thing I wanted to do was kill my rudder stick ( No rudder function ) .. Since this is a Ail / Elevator Bird . ( 3 servos )

Also apparently you need a launch setting for the elevator , so I had to mix a switch for that ..
My first attempt was crude and locked the elevator in a fixed position ( Obviously wrong ) ..

But I got it ..

So now my DLG should be set up ready for Chucking and fine tuning .
I have launch elevator setting and a 3 position switch for flaps ... ( high lift / landing )
For landing I may need to mix in some down elevator - But that will be way down the track ...

Ok it turned out to be a simple correction for me ...
https://www.ebay.com.au/itm/5pcs-Cre...53.m2749.l2649 Got me some of these , fit the Eachine VR006 almost perfectly .

So after playing around for a while , the cure seemed to be to lay the magnifying card over the existing lens on the outside .
All I had to do was cut a grove for the nose relief .
Then use a small piece of tape to hold the magnifier in place ..

And thats it ! How simple ( Bush League ) is that !

Now I can see ! ( To FPV )


Sorry !
At issue was the ability ( mine ) to close focus enough to see the screen ..
Getting a little old ...
Would love to see goggles with adjustable focus _
Any manufacturers out there ?

More HOT HUMID weather forcing me to cower behind air-conditioning ( No I am not a summer person at all ) ...
So what to do ?
The parts were here to play with the DLG .. ( So thats what I did )

My DLG is ready for some chuck tests ...

First thing was to put a battery plug on the voltage booster .
Then test for shorts and adequate output voltage .
Then fit a servo plug with the signal wire removed .
Then I had to bind the 4ch Rx ..

With the Rx bound and the test servo working , it was time to plug the Rx into the servos in the DLG ..
Now with a 4Ch Rx , I had to mix 2 channels ( 2 and 3 ) to get the ailerons working correctly ..
This can be a little tricky with OpenTx , but I got there . ( So many ways to do it wrong )

Once the functions were correct , I limited servo travel so as not to over travel the control surfaces (?)
I might still have to much ... ( from mem 519 is max )
My ailerons are 200 and my elevator is 300 .. ( If you use Open Tx you probably understand )

Anyhow .. The DLG is at a starting point , CG is close ( a few mm forward of fact specs )
Wow , you really cant put much weight in the nose at all ... ( To make Factory specified CG )...Continue Reading

Stuff has happened and stuff has arrived !

My solar power bank has been re-paneled and is outside laying in the sun catching rays .
Got stuff for the DLG , so hopefully get that CG where it needs to be .
2s balance charging board is here ...
Those magnifying bits of plastic are here .

F3 flight board .. its 1s and 2s .. I wonder if I will need higher voltage motors ?
Oh well , I will be doing some Multi meter readings and hopefully wont kill the board ...

So looks like I need a ROUND " To It "

Just working on a FuriBee H801 review at the moment ....

The following is a public service announcement !
I was on Feebay and thought about the Dumpster Brand batteries ! ( Dumpster Brand > Buy some batteries Throw them in the dumpster cos there so bad ) We all know feebay is flooded with garbage batteries , but I find pleasure in testing them just to see how bad they are . ( Rather than how good ) Have we seen the 9800mAh batteries ? ( 18650 ) Yeah there a joke , unfortunately people are buying them and then doing things with them they should not do . So lets get on with it ! I will discharge them ( well I did ) @ 0.5A , to 3v to see how much , or how little capacity is actually in these alleged 9800mAh batteries .

I got these as a pair , and the first discharge resulted in :

Battery 1 = 518mAh discharged ( yeah > thats 518 mA )
Battery 2 = 684mAh discharged ( Jaw dropping right )

2nd Discharge :

Battery 1 = 548mAh
Battery 2 = 682mAh


Would it be fair to say these are monumentally bad . Possibly dangerous , life threatening , absolute garbage that should not be for sale anywhere ? ( Would that be fair ? )
And so endith the public service announcement !

Review was made possible by FastTech AF link

fasttech.com Non AF link



The folks at FastTech have made it possible for me to review the Lumintop SD4A and what a nice light it is . Whilst I am a real fan of the single 18650 flashlight format I also find AA lights very interesting . Modern technology makes it possible for the average Joe Six Pack ( non flashlight enthusiast ) to safely enjoy powerful flashlights and the SD4A is certainly powerful . There is only one thing I can can complain about and that's the power output > it's too high !

The build quality is really excellent , actually from a mechanical perspective I have absolutely nothing to complain about . Everything works as it should , the fits are as good as they need to be . There are not rattles or squeaks , the clicky buttons are excellent . The SD4A is just a pure joy to use and being AA gives you the opportunity to play with a lot of batteries . So before I say anything else lets get to the performance :

Alkaline Batteries :

Low > 39 Lumens / Medium > 470 Lumens / High > 664 Lumens / Turbo > 900+ Lumens ( Output was dropping quickly )

Eneloops : ( nimh )

Low > 38 Lumens / Medium > 370 Lumens / High > 657 Lumens / Turbo > 828 Lumens ( Holding output )

Vapex : ( old nimh )

Low > 38 Lumens / Medium > 370 Lumens / High > 474 Lumens ... The SD4A kicked it down a gear here and as a result

Low > 22...Continue Reading
