  Drone Build: Stinger X210 Racer Drone Build
Posted by: cbb - 06-21-2017, 08:18 AM - Forum: FPV/Drone/UAV - No Replies

Stinger X210 is an OPENSOURCE Racer frame that’s so cute. Main body part is 3D printed canopy! If made of ABS or PETG it’s really strong (you can probably stand on it) and you can get a nice finish (more about finish in my tutorial below). It holds FPV camera nicely in place with easy adjustable tilt angle. In the back you have vtx connector mounting hole and good intake/exhaust holes for ventilation. On the sides there are holes for cables and main battery strap.
[Image: Stinger-X210-racer-frame-01.jpg]
[Image: Stinger-X210-racer-frame-02.jpg]
It has 4 identical arms that can be made in 3 or 4mm CF. I prefer 4mm, but for some weight reduction you can go lower aswell. It has screw “locking” mechanism that allows you to replace arm without disassembling whole build. Arms has also motor ventilation holes (rare!) and motor bumpers. They are wide enough for most “barebone” ESCs. Center will fit the 30.5 and 20mm FCs and below you have room up to 4s 2000mah batteries with OPTIONAL battery protector.
[Image: Stinger-X210-racer-frame-03.jpg]
This frame is opensource, that means that you can make it yourself or ask your local buddy with machines to print or cut the parts of frame for you! That means cheap non-profit frame with local spare parts, fully customizable and upgradeable. If you are Banggood or Hobbyking or someone similar, you should contact me first!
[Image: Stinger-X210-racer-frame-04.jpg]

 

Specs:
– Fully symmetrical X
– 210mm motor diagonal
– Quickly replaceable arms
– Very sturdy frame!
– Printable and customizable canopy!
– Really aerodynamic frame!
– Minimal screws and spacers
– Clean build
– Optional battery protector (12gr)
– around 450gr RTF
Opensource rules:
Makers: No commercial selling of this frame without my approval! You can make it for yourself, your friends or by requests!
Modifiers: You can edit files and modify frame, canopy etc. – but please share modified files so others can use them! No commercial selling of derivatives!
Pilots: You can get this frame locally via CNChubs or 3DHubs by sending files OR by asking for parts in this group. I bet there will be makers in your vicinity.
To make your 3D print look cool, stronger and more resistant to sunlight follow this tutorial:



I used for building next equipment, which proven to be good choice:
This selection is quite cheap and turned out to be really good! It flies on rails, power on demand, all acro stuff! No BEC needed, no modifications, less than 2h build time. You also have OSD for voltage and RSSI and maybe some other things if needed.
We start the build with ESC and motor soldering. If you want to make it real good, with low resistance and good solder joint, than you shorten the motor wires than split the wire end and solder on both top and bottom of the ESCs.
[Image: Stinger-X210-racer-frame-05-768x432.jpg]
[Image: Stinger-X210-racer-frame-06-768x432.jpg]
We do this on all 4 sets. We make 4 sets identical, because we will change motor direction in software. We also add signal cable and main power cables, that are supplied with ESCs.
[Image: Stinger-X210-racer-frame-07-768x432.jpg]
Now we can complicate a little and turn the ESCs so that MOSFETS are facing the arm. We will add heat transfer material between the ESC and arm to allow arm to act like heat sink. Well… you can also just put ESCs in the heatshrink and let them cool by the motor air-flow.
[Image: Stinger-X210-racer-frame-08-768x432.jpg]
Here you can see some of the heat-transfer material, that will also insulate esc from carbon fiber on the arm.
[Image: Stinger-X210-racer-frame-09-768x432.jpg]
And shrink over the boom + ESC, to protect it nicely.
[Image: Stinger-X210-racer-frame-10-768x432.jpg]
We now have 4 finished arms. We make 2 symmetrical arms.
[Image: Stinger-X210-racer-frame-11-768x432.jpg]
This image shows how easily is everything put together. We solder rear 2 escs to the XT60 connector directly, and front pair via Y cable, that is also soldered to XT60 directly. Than we have only 1 more thin wire for FC – directly from 4s. Camera and VTX will be powered also from 4s directly, but via FC, to save some wire.
[Image: Stinger-X210-racer-frame-12-768x432.jpg]
Instead of heavy and bulky PDB, we solder everything to XT60 and cover with heatshrink in the end.
[Image: Stinger-X210-racer-frame-13-768x432.jpg]
[Image: Stinger-X210-racer-frame-14-768x432.jpg]I’ve soldered motor signal wires directly to the FC because I didn’t have suitable connector, but most important is that I made 2 connectors, which I got with camera and vtx and connected them to FC directly (+, – from 4s and video in/out), so I can just mount the canopy and hook up the cables. This is basically it… the build is finished with this
[Image: Stinger-X210-racer-frame-15-768x432.jpg]
I have one less quality picture how camera and videolink are mounted inside the canopy…
[Image: Stinger-X210-racer-frame-16-768x432.jpg]
To mount the canopy and have battery protector in the same time, I’ll use M3 stud inside 35mm spacer. If I don’t need battery protector, I’d just use regular screw.
[Image: Stinger-X210-racer-frame-17-768x432.jpg]
And it’s finished! 2 hours and that’s it
[Image: Stinger-X210-racer-frame-18-768x432.jpg]
I’ve found a nice way to shave off some weight and resistance 6-10grams… now I can use battery protector without weight worries

  FAQ About Basic Knowledge of Power Bank
Posted by: vicky - 06-17-2017, 01:48 AM - Forum: Gens ace & Tattu Battery - No Replies

What is power bank? 
Power bank serve as an extra battery' or external charger for your phone or other electronic devices. It is a portable power source built of rechargeable battery, packed in a small case that can be carried in a handbag or purse. It has at least one input for charging and another recharging port that can be connected to a standard USB cable that can recharge portable electronic devices like smart-phones, media players and tablet PCs.

 Most of the newest power-bank models, arrive with built-in Lithium polymer battery, which known by high efficiency and long lifetime. 

[Image: power-bank-light.jpg] 

How do I know which power bank suits my device? 
Depending on individual needs and requirements, there are several general criteria to consider when selecting a power bank:

 a) Capacity 
For example if your phone battery is 1500mAh and is 0% now, a power bank with 2200mAh can charge your phone 1 time. If your phone battery is 3000mAh and is 0% now, a power bank with 2200mAh will not be able to charge your phone to full because the phone battery capacity is higher than the power bank. If you require a power bank that is able to charge your phone several times, you need a power bank with higher capacity.

 b) Number of output 
1 output to charge 1 device, 2 outputs to charge 2 devices.

 c) Output specification 
1A-1.5A output is generally for smart-phones, 1.5A-2.0A output is generally for tablets.

 How long do I need to charge the power bank? 
It's depending on the REAL CAPACITY of the power bank. The larger REAL CAPACITY, the longer charging time may required. Different charging methods may result different charging time as well. Charging with the original charger will be faster than charging with computer USB port.

 How do I charge the power bank? 
You can charge your power bank via the charger that came with your phone, computer USB port or using other power bank.

 What is the lifespan of the power bank? 
Generally, a properly maintained power bank can retain up to 80-90% of its original capacity at 400-500 charge and discharge cycle (charge then discharge = 1 cycle, regardless of whether you charge/ discharge it partially or fully). Until your power bank no longer holds sufficient charge to meet your needs, you may choose to purchase a new one.

 Where to buy power bank?
 Buy power bank online you can choose Tattu 10400mah power bank, the capacity in fact is 10800mah, and use Lithium Polymer battery cell, high weight and high quality. It charges the iPhone 6S almost 5-6 times, iPad air2 almost 1-1.5times or iPad mini4 1.5-2 times, and also charge Android smart-phones and others.

 General Information
– A = Ampere
– mA = mili Ampere
– mAh = mili Ampere hour
– Output from computer’s USB port = about 500mA
– Output from wall plug (3-pin plug) = varies (please refer to specific wall plug specification)
– Output from power bank USB port = varies (please refer to specific power bank model)

  what jump start car battery safety features
Posted by: vicky - 06-03-2017, 08:23 AM - Forum: Gens ace & Tattu Battery - No Replies

[align=start]Although use the jump start car battery is easy and common, but there a number of risks inherent in their operation. So before purchasing a jump start car battery, you'd better check to see that jump start car battery safety systems. What jump start car battery safety features you need to know? Let us to see.[/align][align=start][Image: jump-starter.jpg][/align]1.Short Circuit Protection[align=start]Short circuit protection possibly one of the most important safety features on a car jump starter, as a short circuit can potentially lead not only to serious damage to the car jump starter, but also a potential explosion of the battery inside the device. Tattu 12000mah 12v jump starter have short circuit protection, no like other brands, their jump starter is extreme safe that even you connect the positive and negative poles together. No worries of any danger of short circuit. So when you purchasing you'd better check it.

[Image: 12000mah-jump-starter-Starter-Short-Circuit.jpg]
[/align]2.Over-Current Protection[align=start]Over current protection is limits the current the jump start car battery will deliver to its peak rated current preventing damage to the device.
[/align]3.Over-Voltage Protection[align=start]This feature prevents too high a voltage from being applied to the unit when charging. Again, this can happen during a mains power surge. Take Tattu 12000mah 12V jump starter as an example: when capacity is up to 95%, battery could not be charged that to prevent over-charging.
[/align]4. Over-Charge Protection[align=start]The charging circuits on more basic jump starters will not automatically stop charging the device when the batteries are full. With overcharge protection, the charging circuit will "float" charge the jump starter once full, and won't keep increasing the voltage applied to the cells, which could then overcharge and destroy the battery pack.
[/align]5. Over-load Protection[align=start]It protects the unit from receiving a current higher than the manufacturer's specification when charging. This may happen during a surge from the mains power feeding the jump starter's charger.
[/align]6.High / low temperature Protection[align=start]Tattu 12000mah car jump starter operation temperature is -10℃ - 55℃. When jump start car battery operation temperature is too high or low, it will make the car jump starter stable.
[/align][align=start]Tattu 12000mah jump starter have all above safety features, if you interesting in their car jump starter, check out:
