That does look like first class work on your Firestar, always a pleasure to

Very nice work and worthwhile mods.
I'm curious about your fuel tank. What are the dimensions and capacity?

Thanks guys for the compliments. Thom as far as the dimensions of the tank I would
guess about 13 x 16, It's 8 gal. Let me know if you need exact dimensions
I'll measure it.

Exact dimensions not required by me. Just curious how much you could carry in a
drum tank.

It sounds to me like the noise canceling will be trying to cancel the sound of
the radio.

sized for the engine.
Also note that this carb, like MANY others, has no linear relationship between
throttle-slide movement and cross-sectional area of the throttle bore opened.
Butterfly carbs have a similar problem.
I thought there was an 'official' definition of 75% power. I don't recall for sure
but it seemed like it was something like 100% rpm, then back off 10% rpm.

John,
>From being on the list for a few years, I questioned your 75% power cruise
statement because it countered my impression of how you flew your planes. I
checked with http://www.rotaxservice.com/rotax_engines and using the numbers
proved from the various engine model spec sheets this is what I found.
engine max hp max hp .75 max .75 max |John's hp % max
model (cont') rpm hp rpm | rpm (dev') hp
582 65 6,500 49 5,300 |5,800 61 94
447 40 6,500 30 5,200 |5,800 37 93
912ul 79 5,500 59 4,000 |5,000 74 94
912uls 95 5,500 71 4,200 |5,000 89 94
Approximately 75%?

By definition it is when or at what conditions the engine is producing 75%
of its rated power. You calculate what that would be, on my 582 it's about
48 HP and according to the graph in the Rotax operations manual for the two
strokes on page 10-3 that occurs at about 5200 RPM.

71 hp divided by 12 hp per gal per hour...comes to abt 5.9 gals
hour... Seems a bit high...I am guessing that the 912uls burns about
5.5 gals hour at 75 % power? Herb
