Rotax 582 consumption

[Dave F]

WOT = wide open Throttle
Stock muffler is the one supplied by Rotax and modified by Kitfox to make it fit in the cowl.


What kind of tach are you using ?

[Olle1975]

I use the Rotax tach, I suspect you use the tiny tach?

It's time for new videos, Dave :-)

What's your EGT?

you got it -- Rotax tachs are not dependable.


EGT is perfect light brown spark plug - The indicated temperature is not a good way to compare as there are variables
-not calibrated.
-they are supposed to be calibrated at 70F

So when you fly at 0 F and the temp reads 1250 F that is not high but the same as flying in the summer at 70f the EGT will read 1180F

The same like mine....

So when you fly at 0 F and the temp reads 1250 F that is not high but the same as flying in the summer at 70f the EGT will read 1180F

Of course, during cold temperature and more airtight you get more EGT, but I think, 1250F is to much for the 582.

Videos - I think I have covered alot of Kitfox ones and still got gigabytes of videos to make......... stay tuned

I look forward to your Kitfox videos....

1250 F is not too much but dependent upon the out side Temp, jetting etc.

Point is that the EGT gauges re not accurate as far as 1200 or 1250 but a good indicator of any changes inside the engine. Spark plug colour is your best indicator.

hi everyone from a newbie, 582 fuel burn/performance...i fly a mk2 and recently put in a blue top but with c-box at 3.47-1 ratio together with kiev 183 prop, result brill 12lt/hr at 80mph cruise 2up and keeping egt's at a respectable 1150, it's a lot quieter and a lot smoother as well.
Hope this helps.

I've found two nice videos about burning fuel during 6000 rpm and low EGT and about 5500 rpm and higher EGT. I think, the right rpm and EGT-temp is the way for a economic fly. The altitude is an additional reason.....
