Update:
Pictured is the wing with ESC - Motor - Servos , sorry no Rx ..
Total weight in parts ( Without the Rx and battery ) 71.3 Grams ...

It just might be possible to build a 100 gram RTF wing .. Oh yeah the 6 amp ESC finally got here ( Already tested ok )
Will most likely make a start this week on the wing , they are very simple to build . First I will install the motor / ESC ( already soldered together ) .

For review I have the Klarus XT2CR a 1600 Lumen EDC able flashlight with two modes of operation , Tactical and Outdoors . And right off may I suggest that the outdoor modes are the choice modes for most people . The XT2CR came set to tactical out of the box and initially I was left some what confused by exactly what Klarus was trying to achieve with the mode of operation ( Tactical ) . The XT2CR has two switches at the back of the tailcap , the main switch and a mode switch . Pressing down on the mode switch in the Tactical mode short cuts to strobe and the only way to stop accidental activation is to unscrew the tailcap . ( Lock out the tailcap ) There does appear to be mode memory , but its the strangest mode memory ! and only seems to work for Low , though a few times I got the light to go into medium ? ( Very strange ) But then there is no mention of mode memory in the instructions ?

User Interface :

You have two switches in the tailcap . The main switch ( a forward clicky ) and a mode switch . The main switch turns the light on or gives you momentary function with Turbo output . There are two modes of operation , Tactical and Outdoor .

Tactical = 3 Light levels ( Turbo - High - Low and strobe function )

Outdoor = 4 Light Levels ( Turbo - High - Medium - Low and SOS function ) .

Changing Mode = Instruction manual sux's for this one : Hold down the mode switch , a green...Continue Reading

Still waiting on 2.5g servos .. ( For my wing )
Also waiting on plastic washers to fix my Q333 ...
The Eachine E010s Pro = Seems to have some sort of Rx issue ( Quad side ) - Maybe damaged - Box looks like it was drop kicked .
What I might do is put the camera on my B-Whoop - Since the E010s wont fly , hmmm , I might also swap out the board (?) , since I did buy this replacement board .



Sounds like plans are forming ...

Came today ! Yay ! Eachine E010s Pro
Sent for review / testing by Banggood.com
Link to Banggood page Non affiliate link ...

1) You do need to program before flying
2) Inbuilt Rx - Flysky - FrSky - DSM2 ( Pick one ) I went with FrSky
3) The camera was double sided tapped to the canopy = Be very careful removing the canopy
4) The Rx antenna is a bare wire - Might want to route it some where safe before firing up the E010 ..
I might remove it and solder in a covered / insulated wire ..
5) Betaflight for programming ...
6) Bag of goodies = Spare props - USB charger - 1 prop remover - 3m Double sided tape ( for camera ) - and some rubber bands (2)

A1405 motor from GearBest (0 min 56 sec)


So we know that peak current was 3.15A / 25 watts with all props tried , 5x3 - 5x4 - 6x3

So this tells us that none of those props really loaded up the motor , also tells us the 3000kv claim is just a claim .
I put the motor to the Tacho ..

4.5x3 = just over 11,000 RPM > Oh dear !
6x3 = just over 10,000 RPM

My guess would be that this might be a 1200 - 1400kv motor , ? ( 1400 at best ) ..
I could be tempted to try a 7x3 if I could find one physically light enough , because this is a very small motor or maybe a 5x5 ...

Well those 1.5mm screws showed up today .. ( I thought I had a 6A ESC ? - Must have misplaced it )
Anyhow .. I have a 12A ESC I can test with .

Motor is 1s - 2s so we will be using a 2s Battery ..

GB gives no specs on the motor ..
HK has a motor !

A1405
30 Watts
6A
3000kv

So using a 2s battery and ...

5x3 - 5x4 - 6x3 and a cut down 5x3 to 4.5x3 .

First I tested current draw and Watts , every prop was around 3.15Amp and 25 Watts and the motor ran cool . So obviously I am not maxing out the motor at all . Then for kicks I got out some cheap electronic scales and I tested for thrust . Motor is mounted to a wood block , I am setting the motor up for pusher ( push down ) to see how much weight the scales register . Obviously with the motor off one sets the scales to zero ...

5x3 prop gave around 110 grams of thrust .. 5x4 prop was about 115 grams and the 6x3 was around 120 grams , but obviously this is static thrust . Pitch would have something to say about flight performance , so I will go with the 5x4 ...

Well with about 3A current draw , around 110 grams of thrust .. I think the motor will fly my wing , especially if I can make it 100 grams RTF ..

Not sure the GB motor can live up the the HK motor specs , just does not feel like a 3000kv motor .. Its dark and tomorrow I will tack the motor with the 4.5x3 prop as it did rev out a little more on the little spinner .

My wing is here from FastTech dot com ...
I put it on the scales and got 46 grams ( for the foam components ) , that leaves me some 54 grams to play with to get to my goal of 100 grams RTF
Just waiting on the 2.5g servos now and some small ( 1.5mm ) screws

For review : Nitecore EC22

Product Page @ Nitecore

Nitecore EC22 provided for review by Nitecore



I was looking at flashlights one night ( as I some times do ) and I spied the Nitecore EC22 . Two things grabbed my attention right away , the first being the infinitely variable output and the second was the rotary dial . Never mind the 1000 lumen output or the fact that it it's all put in a very handy package powered by a 18650 or two CR123 . The very first thing I did on receiving the EC22 for review was to take it for a walk . Nope ! , I did not measure current or put it in the light box or anything else . I wanted to experience the EC22 first and then see what the numbers were . When I went for my walk I swung past a friends place and let him and his wife have a play with the EC22 . Now my friend took to the EC22 like a duck takes to water , without any prompts from me he had turned on the light and was adjusting the output . For a non flashaholic to simply use the light so easily tells me that the user interface is universally simple , kind of reminds me of a transistor radio with its rotary dial for on and of and volume control .

After visiting my friend I swung past the local park ( its a big park ) and the great thing is that the road / foot path is raised several meters above the park allowing some one with a flashlight a nice elevated position for shinning a light . For a light with small head and short reflector the EC22 did not...Continue Reading

Banggood sent me the Eachine EV900 FPV goggles to test / review . Now I was not really sure what to expect having watched a few other reviews and the reviewers being less than kind to the EV900's . Almost every review out there complains about the goggles riding the bridge of the nose and I would have to be no different in this regard . Though for me it's not nearly as bad as others claim . I can see the screen just fine and only the very bottom of the screen is obstructed . The other thing I did was to add stick on foam to soften the load on my nose .

Is the problem as bad as some claim ? For me , NO . But to be fair it is annoying .



The very first thing I did on receiving the EV900's was to plug them in to my graphics card VIA HDMI and yes there is a HDMI cable included . I really overdosed myself on the experience playing FPS and watching youtube video . I totally lost track of time and I have no idea of how many hours I spent with the goggles on , but it was long enough for me to be exhausted / dehydrated and some what nauseated . Too much of a good thing , and I think I now understand how some one could die in front of a computer . It is an addictive experience for sure .

The second thing I did was test my FPV models , I have two micro quads and the WL Toys 12428 buggy set up for FPV . I have to tell you the image quality is outstanding...Continue Reading

Eachine EV900 FPS sample VIA HDMI cable (1 min 38 sec)


FPS = First Person Shooter ( gaming )

Sent for review / testing by Banggood

Wow , I was sent the Eachine EV900 goggles for review / testing and one could no help but notice the HDMI connector ( and included HDMI cable )
So what is a boy to do ( a old boy )

I still play games ( and why not ) , so I connected the HDMI cable to my graphics card so I could play looking through the goggles .
The video sample provided is close to what my aging eyes see .. ( Which is far better than other goggles I have used without correction )
In fact I am very pleased with the color , and sharpness ..
The camera is @ 14x zoom so there is IQ loss , so bear that in mind . But it actually reproduces at this setting what my aging eyes see .

I spent way too much time playing with the goggles on ( lost track of time ) , not really sure how healthy it is as it leaves you some what detached from the real world which can be disorientating . ( We are talking hours here ) .

I also did some youtube ( VIDEO ) which was surprisingly good .. So if you had a small DVR-Player with HDMI , you could watch movies on the go .. The Eachine EV900 also has a headphone jack ( havent tried it yet ) , so you really could shut out the outside world if you wanted to .

Are the Eachine EV900 a replacement for your computer monitor = NO ! in no shape or form would I say so .. Could...Continue Reading

Previous post = Part 1 ...

Product page @ banggood

I bound the Rx to my Taranis Q x7 = Easy .... And then made a range test box . ( Pictured )

Bind process ....

I went into the menu of the Q x7 and created a new model ..
Then set the transmitter to D8 ( 1-8 ) mode ...
Then set the Tx into bind mode :

With the Tx in the bind mode :

Rx .
I had connected a UBEC to Ch1 and a servo to Ch4 ..
Before applying power I press and hold the bind button and whilst holding the bind button apply power to the Rx .
The bind is almost instantaneous ...
I let go the bind button and disconnected power to the Rx ... ( Get the Tx out of bind mode )
Turning on the Rx again - it was bound to the Tx ...

Putting the Tx into range test mode , I started walking away from my range test box .
Facing the Rx I made it to the maximum distance I can get from the Rx ( 60 meters ) ... And there was no issue ..
Facing sideways there was no issue ..
But turning away ( 180 ) from the Rx so that my body was between the Rx and Tx I did lose the signal ...
