Chris Gill just landed after an epic, record setting flight from Denbigh. Using wave for the first part and then the late afternoon thermals to stretch the free distance Chris just extended the 3 turnpoint distance record for the UK from 1100 km to 1357 km!

06:15 winch launch and use the motor to contact the local wave, climb to fl194 and cross the water 120 km to the Lake District. then across the width of the UK. 4 times and back across the water to pass the home field and almost make it to Aston Down.

A truly epic flight!

I gave up trying to get an oil tank level sensor that 'just worked' with my installation.

So I developed my own.

ESP32-C6 + A02YYUW Ultrasonic Sensor and I added a BME280 breakout.

The assembly sits outdoors installed in the top of my oil tank so using the system to get the outside temperature, relative humidity and atmospheric pressure was a good idea. I may update it to add a light sensor to read ambient light levels too.

I haven't bothered yet with powering it off solar and or batteries but that's an easy step and for the moment I have a wall wart feeding the sensor with 5v.

Integrated straight away with my Zigbee network.

Guess which house I was delivering to! Yup the one that 2 appliances had just finished putting out the fire in!

Not quite a Perlan tow but around 1/3 their height. We were asked to test the real world capabilities of a Eurofox 915is tug for the benefit of someone looking in to renewing their tug fleet operating off a hot/high airfield.

Climb rate was good right up to about 14500' and then tapered off. At 16000' climb rate dropped to 1kt so we knocked it off.

Eurofox 915is and DG1001 Neo, fixed gear and about 190 kg in the seats. At 16000' the temperature was around -5°C so 12° above Standard for a density alt of about 17500'.

Eurofox tugs are very capable!
