This is really great accomplishment:-)

Montreal, Canada: EnergyOr Technologies Inc., a leading developer of advanced PEM fuel cell systems, recently demonstrated what are believed to be the world’s first fuel cell powered and longest ever duration multirotor VTOL UAV flights, flying for a record 2 hours, 12 minutes and 46 seconds.

Konbanwa!

What do you fly and is your field close to Tokyo? I'm located in Meguro and mainly into UAV aircraft, although just started to fly a KKmulticopter.

I'm living in Atsugi. It looks like lots of space to fly air craft in Atsugi. However, there are very few places to flay.

This is my main frustrated issue. You can visit my web site. It is some sort of language translation web site. http://aeroquad.at.webry.info/

Jiro, thanks for the suggestions on demonstrating the heli in Tokyo.  I might give that a try at the Tokyo Institute of Tech.  I guess the make fair is at the ookayama campus.  I'll ping you when I'm getting close to being ready..

Hi Jiro, I have an issue regarding the use of xbee with pixhawk, I'm using xbee as follows, 

but I´m still having problems. I write the next program to try send some data but I don't get any positive results.

#include <AP_Common.h>
#include <AP_Math.h>
#include <AP_Notify.h>
#include <AP_Param.h>
#include <AP_Progmem.h>
#include <AP_InertialSensor_MPU6000.h>
#include <AP_InertialSensor.h>
#include <AP_ADC_AnalogSource.h>
#include <AP_ADC.h>
#include <GCS_MAVLink.h> // Rediculous dependency to AP_InertialSensor_MPU6000
#include <DataFlash.h> // Rediculous dependency to AP_InertialSensor_MPU6000
#include <AP_GPS.h>

#include <AP_HAL.h>
#include <AP_HAL_AVR.h>
#include <AP_HAL_AVR_SITL.h>
#include <AP_HAL_PX4.h>
#include <AP_HAL_Empty.h>

const AP_HAL::HAL& hal = AP_HAL_BOARD_DRIVER;

AP_HAL::AnalogSource* ch;
AP_InertialSensor_MPU6000 _INERT; // MPU6050 accel/gyro chip

void setup (void) {
hal.uartA->begin(115200); // USB
hal.uartC->begin(57600); // RADIO

_INERT.init(AP_InertialSensor::COLD_START, AP_InertialSensor::RATE_100HZ);
}

void loop (void) {

hal.uartA->write("start \n");
hal.uartC->write("m");
hal.scheduler->delay(20);

}

AP_HAL_MAIN();

Do you have an idea of what is happening?

Thank you in advance.

Regards.

Hi Gary

Do you have good communication through Mission Planner by your setup?

Please separate an issue for hardware or your software.
