Hi Ellery

  With your 447 at 75% power ( about 5,100 rpm ) Whats your fuel 

consumption???



  The ROTAX Operators Manuel on the KODIAK RESEARCH site states 5.3 (at) 

take-off performance... ( I assume this to mean full power at 6,800 RPM)



  and lists at 75% power ( 5,100rpm ) a burn rate of 3 Gallons Per 

Hour....



  Is this your findings here in New England ? And do you find the 447 to 

be enough

 motor for your Firestar or fly --- Which do you fly???



 Thanks

 Mark

Hi Ellery

 That's decent enough...



 So using 3.5 per hour would be a good estimate for XC use

 That leaves you some full power climb and reserve wiggle room... 



 On a stable day roughly what's your ground speed at 5,100 rpm ?

  And lastly what's your Gross Weight .... You said it was a FAT 

firestar ?



  Also I see you have one listed on the BarnStormer is that the FAT 

one????

Why you selling??? For that matter Why are a lot of KOLB owners selling 

???

is it a SPORT PILOT rating issue????
