T/BIrd Fuel Consumption

I met two gents at the airfield this weekend who fly Rotax 582 equipped Thunder Birds. Both of them use about 20 litres per hour down here at the coast :shock: Is that normal?

Hi Griffin,

20 lts/hr sounds a bit high to me (unless 2 really big okes and trying to fly fast, which t-birds don't do well).

I've just got back from Dragon Peaks flying solo most of the time. Average for the whole weekend (±15 hours flying) was 17 lts/hr. I have a stratomaster fuel flow thingy, and if I fly really carefully, I can maintain 60 mph at about 15.5 lts/hr, but it takes lots of work.

The specs list it as 15l/hour at 6000ft so the 20l/h seemed a bit high at the coast. I wonder if the prop pitch setting could be the problem?
