The only Universal Smart Remote Control for TVs and Home Electronics you'll ever need!
Smart IR Remote is the only IR remote universal app for Android that you'll ever need: it's smart, with a device coverage that is huge (800000 devices, with more added daily and on request), and it's the only one that makes use of features only your phone/tablet have, that a plastic remote (like the Logitech Harmony) never will. As IR remote controls go, especially android remote controls, you'll never find one better!
Not compatible with Huawei, Vizio or Sony phones. Of all phones/tablets by LG, only compatible with the G3 (still in Beta, sending only, not recording. Not compatible with LG G3 A or LG G3 S)
Don't have a supported phone or tablet? Check out AnyMote Home: http://anymote.io
Smart Remote works with any Samsung, HTC and Medion Lifetab devices with an InfraRed Blaster, and most other brand phone/tablet with an IR Blaster that runs Android 4.4 or above provided originally by the manufacturer. Even better, Smart IR Remote also works on most custom ROMs like CyanogenMod.
Smart IR Remote is an universal smart remote control that can command almost anything that receives InfraRed commands, like a TV, Set Top Box (cable and satellite box), DVD, BluRay player, VCR, Amplifier, Air Conditioner, AV Receiver, DSLR camera, etc. Better yet, you can combine your remotes into smart remotes (activities) so that on your custom remote you'll have the volume buttons to your surround system, the channel buttons to control your set top box and the display buttons to control your TV. It's the only Android universal tv remote that can do that, while controlling any other device too!
Have any questions? Visit our FAQ: http://colortiger.com/faq.php
If your remote is missing, please email us and we'll do our best to help!
On top of all that, since you're holding a phone, why not use some of its unique features?

Simply wave your hand above your phone to change channels, volume, or whatever your heart pleases - it's all configurable!
MUTE/PAUSE ON PHONE CALL
Smart Remote can now mute your TV, pause your media player, or even switch them off if you wish, all of that when your phone rings.
Group commands in batches, sort them and add delays, and then execute the series of commands one after the other. Imagine being able to turn your TV, Xbox and surround system on, switch TV to HDMI 1 all with a single tap!
Automatically execute commands or macros when certain conditions occur: your phone rings, at a time chosen by you, when you use your phone's Volume Buttons. Are you a Tasker fan? We have a Tasker plugin that lets you to send commands
With homescreen widgets, you'll have your favorite commands just a tap away when you grab your phone. Need something even better? read on
FLOATING REMOTE (CHATHEAD)
The floating remote is a remote that stays above other apps which can be shown with just a single tap and lets you send commands even while you're playing a game on your phone
BACKUP / RESTORE

All available interfaces of mobile phone (GPS, accelerometers) are used for telemetry and internal camera can be remotely controlled to take pictures or video during a flight or a ride.
You never loose Your model now - "Show model on map" feature enables You to check model position based on its GPS coordinates just by one menu command execution.
An external module based on Arduino with Bluetooth interface can be used for battery measurements (LiPo, Li-Ion cell voltages), servo control and other IO functionality (Amarino communication framework must be installed to use this feature, application for Arduino is available for free download on our website). Using this piece of hardware extends telemetry capabilities a lot, but it is not necessary option, You can use all other features of MPBC without this module.
Telemetry data can be stored periodically for post-flight/ride analysis in CSV format using integrated data logger.
Data exchange between "board computer" and "remote client" goes through Internet and is managed by our MPBC server - this communication is enabled for subscribers only, so if You want to use this feature including up to 16 models telemetry configuration storage, please subscribe directly from MPBC application.
There is a 60 days FREE trial period for subscription, so You can test all features of MPBC with no risk - if You cancel subscription before trial period expires, You don't pay anything.
Once You subscribe You will be still able to upgrade to latest application version and benefit from newly added features. You need only one active subscription for Remote Client device, Board Computer device attaches to Your MPBC account after entering acces codes even if this device is configured for different Google user account, so You can use Your friend's or wife's mobile as a Board Computer without reconfiguring its account.
Do You have some older Android mobile phone at home and were You thinking what to do with this device, when You have purchased a brand new Android phone for Your daily use ? That older one can become a Board Computer for Your RC models !
Do You have an Android mobile phone and also an Android tablet ? Then You can use Your phone as Board Computer sometimes and Your tablet as a Remote Client easily !
For more info please visit MPBC on-line help available at "http://www.modelport.cz/mpbc/index.htm"
All comments and ideas are welcome, simply contact our support at "mailto:email@example.com"
Many improovements and functionality extensions are planned, so if we get subscribers support, You can expect them soon.
Enjoy Your flight or ride !

I use these calculators often in my modeling and I find them handy for making educated guesses at the least. More calculators and features are in development. I have many more needs and now that I have the basic application and framework in place, I am creating new features as I need them. More free updates are coming.
The calculators and features in this release are:
• Unit Converter
• Wing Area
• Wing Loading
• Pitch Speed
• Engine Size
• Tank Size
• Gas / Oil Mix
• Propeller Chart
• Drill Size Charts
• Battery Voltage
1. By using a yardstick.
2. By using the mobile camera.
3. By using the mobile sensors.
Process for 1. and 2.: You have to scale and type the rotor blade length (hole to end). Both blades has to show in the same direction. If you have 0 degrees pitch the blades have to be exact parallel. If you change pitch, the blades are moving apart. By using the gap between the blades you have the pitch value.
Process for 2.: By using the mobile camera it is enough to type a nearby blade length in the programpart 'calculate pitch'. After selecting the camera icon, you have to make a photo from your blades of the helicopter (like the title picture). Then you have to move the lines upon the blades. The ends of the blades are less important. Important is, that the lines are upon the blades (parallel).
Process for 3.: You can fix you mobile at a blade by using an elastic strap and read the pitch from the display.
-Bugfix: pitch with sensor (for some devices)
- Bugfix: If no camera app is available.
V 2.6.10 / 2.6.11
+ Pitch with Sensor: Movement now a bit smoother. I have changed the method of painting the view. Maybe it has fixed the Samsung Galaxy 2 bug. If the problem is still existing, please send me an email to firstname.lastname@example.org with a short description. Then i can give you test versions.
+ Look is now android version independent.
+ Pitch with Sensor: now you can change the sensor orientation by using the menu. It is useful for some mobiles, because of different orientations. (Thanks to Volker)
V 2.6.7 / 2.6.8
+ Graphic improvements (Pitch with sensors / number wheel)
- Bugfix: OutOfMemory in Pitch with sensor
- Bugfix: crash program, if an old value has not a valid value. (Thanks for report.)
+ Graphic improvements (Pitch with sensos)
+ Input of numbers now with number wheel.
+ move to SD card (with Android 2.2)
+ Now with min and max in 'Pitch with sensor'. Min and Max are applied, if the pitch value is 2sec fix and greater then +/- 2°.
+ Pitch is not bouncing this hard any more .

Use RC E-Calc Pro Calculate the following:
- Average Current Used by the aircraft during a flight/run.
- Average Discharge Rate (C-rate) of the LiPo battery during a flight/run.
- Expected Run Time at average current used.
- Expected Run Time using 100% capacity of a battery.
- Expected Run Time using 80% capacity of a battery.
- Realistic Run Time using 80% capacity of a battery and (selectable) average throttle.
- Power in Watts from Volts & Amps.
- Volts from Power(W) & Amps.
- Current in Amps from Power(W) & Volts.
- Static thrust of a propeller in pounds or kilograms.
- Power to Weight Ratio in Watts-per-pound or Watts-per-kilogram.
New for v2.1:
- Unit Conversions (Torque, Mass, Length)
- Cubic Wing Loading (Imperial and Metric)
- Wing Loading (Imperial and Metric)
New for v2.21:
- Resize and refit for better display on tablets or devices with very large fonts
- Reworked Unit Conversions
- Cosmetic improvements to layout
- throttle value choice in Approximate Flight Time
New for v2.3
- Added Battery cell gravimetric energy density calculation in Wh/kg
- UI enhancements and fixes
- Smaller fonts
- Cosmetic improvements to layout
- Unit Conversions improved
(Note: It is highly recommended to fly using only 80% of the capacity of LiPo batteries to maximize their longevity)
a) If your system uses 16 Amps, input 2200mAh and 16A into the app and it'll calculate that you should be able to fly (at FULL throttle) for 6 minutes 36 seconds until the battery is 80% depleted or 8 minutes 15 seconds (also at FULL throttle) until it is 100% depleted.
a) "Realistic" flight time is also calculated which works out to be 11 minutes and 47 seconds using 80% capacity and 60% average throttle, very close to the actual flight time in the second example.
b) You have flown (or driven) for 11 minutes and 20 seconds, then recharged your 2200mAh LiPo, when finished your charger states that 1720mAh was returned to the battery. This app will then calculate:
- that the average current draw for the flight was 9.11 amps,
- the discharge rate was 4.1C,
- you used 78% of the rated capacity of the battery and
- to use 80% of the battery's capacity you could've safely flown for 11 minutes 35 seconds.
