On another note: today a glider&tow meeting, I did not count them, but I think I.ve done about 25 tows, gliders ranging from 700 grammes and slightly over 1 metre WS to 4kilo and 4 metres wingspan, release heights 200 to 250 metres (600 to 750 ft).
The Boxer's getting thirsty when it has to work hard, and I went through 700 ml (23 oz) of fuel...

It was a lot of fun.
