Ever want to practice a new sequence but your buddy hasn't shown up to the field to call for you? This application answers the need for Precision Aerobatics pilots for NSRCA/F3A/Classic/Senior Pattern and/or IMAC (International Miniature Aerobatics Club) or any other discipline where you need a hands-off reminder of what comes next in your routine.

Aerobatic sequences are pulled from the cloud so when new sequences are provided by the NSRCA and updated in the cloud (as I just did for Advanced and Masters) they are updated for all users instantly. You can also add sequences of your own (i.e. old-school classic personal sequences) or customize the standard sequences so they are called the way you want!

Voice recognition call control ("Next", "Repeat that", "Back") works well in a quiet environment, but at the field, you will probably prefer tilt control. I used a QuadLock mount attached to the back of a cheap iPhone case with the lock mount on the bottom of my transmitter. Set up your sequence, turn on tilt control for roll or pitch, mount the phone to the bottom of your transmitter and then when you are ready to start the call, hit the play button on your headphones, the app will calibrate to the position of the phone and you can roll right to advance the call or roll left to move back a maneuver.

Regardless of the control settings, you can always use your headset remote to control the call, a "next song" click on the remote will advance the call, "previous song" will move back a maneuver.

What’s New

Version 1.3.2

Support for iPhone X display size

Use http over TLS (https) for communication with the unknown generator

Updated corebluetooth interface for use with the RC Receiver->Bluetooth bridge device.

Well, it's a good idea but, it is almost impossible to fly and have the app call the maneuvers, it freezes or it just won't go to the next maneuver
I tried the tilt and voice recognition with no luck
I hope you can work on this issue

Current version supports a receiver->Bluetooth bridge I have designed (and have a few available). Next version currently in review supports Bluetooth pedals like musicians use to advance their sheet music on iPads. Hope that helps you out!

Useful program with Bluetooth module

I'm getting back into Pattern after several years of not flying. As I'm newly retired and can fly most any day, this program allows me to learn my sequence quickly at the field when others are working. I tried the 'tilt-to-call-the-maneuvers' option and it worked decent but I did not like that I had to move around so much (tilt my iPhone). The voice recognition option to call maneuvers was difficult for me to get working given background noise. The answer for me was the Bluetooth option which worked great - and the only downside here is you needed a second receiver and battery plus room to mount these items. I had these requirements and all worked out well. I did not find much use to go backward in the sequence (an option with a three position switch on your transmitter) as I'd already flown the maneuver and wish there was an option to call the maneuver over again in case I forgot part of the current maneuver.

Many of today's transmitters have the ability to speak / playback your own voice which may make this program obsolete in the coming years, but for now it works well for me with my older transmitter and the Bluetooth option.

Bluetooth headset mic

The app's voice recognition works ok on iPhone 5s native mic but it does not work with my Motorolla Blutooth ear piece. Is there a way to fix this or is tied to the iPhone built in microphone?

Developer Response ,

It’s tied to the currently active audio device, but many Bluetooth headsets only activate the microphone in phone call situations and I haven’t found a good way around that. The next version (currently in review) supports a Bluetooth pedal like musicians use to advance their sheet music on iPads. Pedals cost about $60.
