Review of Vifly Finder 5V Super Loud Buzzer Tracker Over 100dB Built-in Battery 36 Hours for RC Drone

Notice: Now BG sell Vifly Finder v1.2 of this battery powered buzzer - lost drone finder- "New V1.2 Version, support 36 Hours beep"



This summer my friend RC pilot and I were flying over the woods and he crashed. Lipo on his drone got disconnected in crash so he lost possibility to turn on buzzer on his drone . We were looking for his quad for 6 hours and couldn't find it. Loss to be greater, he had GoPros 4 on quad with lots of flight footage. It was lost too.
That evening , when I got home, I ordered immediately this little device. It can work as ordinary buzzer, but slightly louder, but more important it has its own builtin battery so it will sound even flight pack gets disconnected from the quad, plane etc...


I highly recommend this product.


Specification:
  • Brand Name: Vifly
  • Item Name: 5V Buzzer for RC Drone
  • Built-in Battery
  • Size: 23x13x16mm
  • Weight: 4g
  • New V1.2 Version, support 36 Hours beep



Features:
- A Working Buzzer after Battery Ejection
VIFLY Finder is designed with a built-in battery that gives it the power to sound an alarm even after the quad battery was disconnected.
VIFLY Finder charges itself simply by being plugged in.

- Much Louder than Standard Buzzer
To easily find the crashed quad in long distance, VIFLY Finder is designed to install a very loud beeper that the dB is over 100.

- One-Button Operation to Disarm the Buzzer
To disarm...Continue Reading

I tried to control Mini Convergence VTOL with Futaba transmitter.

Control E-flite Mini Convergence VTOL with Futaba TX (0 min 16 sec)


MCV supports only Spektrum serial reciever(SPM4648), so I needed to simulate Spektrum serial.
Spektrum serial is 12500bps, 8bits, No parity and 1 stop bit. SPM4648 sends 16byte packet every 22ms.
First I thought to convert from SBUS to Spektrum by Arduino or mbed but fortunately
I found "SBUS to PPM or Spektrum Serial Converter" is sold on the internet, so I decided
to use it.
I needed to modify the firmware of the converter slightly to match the output of SPM4648.
Since the voltage of MCV's receiver connector is 3.3 V, I took 5V from unused servo connector
of the MCV to power the converter and the SBUS receiver. The signal from the converter is
level-shifted and input to MCV.

So I recently got back into RC helicopters after a lengthy break and selling all my old stuff. I've already got 2 blade nanos and a blade 130s with a dx6e tx. It's good to be back and I'm thoroughly enjoying it

I just love this plane. It flies so well and I have lots of fun + it looks just awesome in the air. Maybe one day I will build a bigger version.

Custom 250 Quad - Dustoff #1 - I wrecked it but good ;-(

Ground Control RC Custom 250 Quad - Dustoff #1 - I wrecked it but good ;-( (5 min 14 sec)


Well, I haven't flown my custom 250 quad in months.
Time for a DustOff flight ;-)
I just flashed my Flight Controller with BetaFlight.
The Flight Controller is an old CC3D unit.
This flight is to check it out and see how out of tune it is.
Sadly, I ran out of talent on a very bad default setup.
I had a lot of drift and vibration when flying through the prop wash.
I should have waited to get the tune accomplished before performing much acro not mention the fact that I am way out of practice.
I haven't evaluated all the damage yet to see what can be salvaged.
I guess I'm lucky I already have upgrade motors on order for this quad, I'm certainly going to need them ;-)

Build, Fly, Crash, Repair, Rinse & Repeat!

Happy Flying!

Yeah ! , some one has the dollar bug !

Seriously , a long time ago you could buy something for a dollar . ( I mean a long time ago - like the 1970's )
Those times are long gone , well so I thought .

Apparently , you can still get stuff sent to you ( mind you ) for a lousy dollar ...

And so what we have here is a little chucky ..

Building one is incredibly simple , you just need a match stick or something to punch out the cut outs for the wings N things .
There is no need for glue ..
This particular chucky is a stunt chucky ..
And by that I mean it is supposedly meant to do loops when you hurl it ..
If you look at the pictures you will notice I cut a new slot for the elevator so the chucky would glide straight ..
And glide straight it does ..

Only real issue is the weight , or lack there off !
These are really meant for indoor flight as the slightest breeze has a huge effect on the chucky ..
A school hall or something would be brilliant .
If you plan on relocating the elevator , a very sharp cutting tool will make short work of cutting a new slot ..

Flight trimming was easy , just tweak the foam wings or elevator to suit . ( They are very easy to mold with your fingers )
I was really amazed at how well such a small light chucky can glide without a breeze upsetting it .

What I like ..
1) Cheap @ $1
2) Easy to build ( Kid safe )
3) easy to tune
4) relatively robust

What I don't like
1) Stunt version (?) Will need a sharp cutting implement to correct
2) Indoors only - gets upset by the slightest breeze

In OpenTX a channel is a pipeline of calculations starting with the Source you use to control the channel and ending with the output of the final channel value at the receiver. You set up each channel by adjusting the various parts of the pipeline so that they change the value provided by the Source into the value you want to emit from the receiver.

Source->[INPUT->][Trim->]MIXER->OUTPUT->[OverrideCH->][PPM Center->]Module->Protocol->...Radio-Transmission...->Receiver->[pwm|cppm|sbus...]

The channel pipeline is run periodically, sampling the current value of the Source, transforming it and sending the transformed value to the receiver which emits the value is some form. The receiver gets a new value each time the pipeline is run and so receives a stream of incrementally changing values for the particular channel. Since there is more than one channel, the channel pipelines are processed together and the channel values from each period are typically bundled together sent to the receiver in single data packet. The form this takes depends on the protocol being used. The receiver pulls each channel value out of the data packet it receives emitting it to the appropriate place (eg the PWM pin for that channel or the channel slot in the SBUS data packet)

The latter part of the pipeline is set up by choosing a Module, a Protocol and appropriate Receiver. While you do have to choose which to use, this part of the pipeline is mostly...Continue Reading

Sources.
The standard continuous controls (sticks, pots, sliders) give values between -100% and +100% and switches give one of -100%, 0% or +100% depending on the type of switch. Other sources like Telemetry values may have different ranges.

INPUTS.
INPUTS are for adjusting the value a control or other source gives. Each INPUT groups a set of "lines". Only one line from an INPUT is used at once. A line defaults to active but may be made conditional on a real or logical switch position using the Switch field. If the Switch field condition is true then the line is active. For each INPUT, the set of lines is checked in order from top to bottom and the first active line found is used to calculate the value for that INPUT. If there are no active lines then the INPUT will "Hold" it last known value. The basic INPUT line calculation is given by this formula...

INPUTn = Weight*Function(Source) + Offset

While the numbers are presented as %'s to make them easier, for the purposes of the calculation it is better to consider the numbers as being a decimal fraction between -1 and +1. Weight can be in the range -100% to +100% and scales the Source value. A 70% weight means multiply the Source value by 0.7. This also has the effect of setting the minimum value to -70% and the maximum top +70%. This is often refereed to as the "rate". Offset adds a constant to the value. A 10% offset means add 0.10. This will change the minimum from...Continue Reading
