Data glove --> throttle control and flight instrument

This is my latetest gadget, a "data glove" controls the eHayabusa and serves also as flight instrument. The OLED display is very bright and clearly visible from a distance. It shows the system status (System off, flight data) and does not disturb the hand movement in any way. Very handy.

Here is a short video of a test run to see how it functions. The system is still modular and can display any information provided: flight time, sensor information, heading etc. It is connected to the Ardunio by a I2C bus which works fine with 1m cable.

New battery position

The belly pack was nice, but has an inconviniency while starting. It changes the harness fit and limits the movement. So I finally decided to put the batteries in the housing. 2 sets of 8000mAh 12s Lipo cells fit perfectly and are secured with a velcro strap.
The batteries weight in total 4 kg so that the overall weight of the eHayabusa is from 4-6kg depending on batteries.

Controller change

I changed the controller from an old Arduino Uno to an Arduino Nano. There is not really a weight problem, but the smaller Nano fits better in the housing.
Here you can see the size difference:

The Arduino Nano controls now also the "data glove" flight instrument.

Heat managment (2)

To activily control the power output due to heat dissipation I installed 2 NTC sensors. One for the motor and one for the ESC. As the heat dissipation is slow, there has to be an offset for the cut-off temperature. I tried several configurations and about 45ºC gives good results for motor and for ESC. The real temperatur of the motor is about 80ºC when the sensors gets to 45ºC.
The motor is than powered down in a cooling mode, not completly shut-off. For about 2 minutes the motor can only run with low RPM and the small propellers realy cool down the motor.
Here is the photo of the motor rod with the ESC and NTC sensors.
