hello group,

I just bought a used Firestar II  with no manuals and need to know what the minimum pilot weight is  or,  Where can I find weight and balance information.



Thanks

Galen

Galen,



On Firestar II's, the minimum pilot weight is determined by the aft CG limit with full fuel. On mine, it is about 150 pounds, but is different on each plane. So if you didn't get any CG info with the plane, I suggest that you weigh the plane and calculate the minumum. I don't have my plans handy, but I do have an Excel program for calculating Firestar II w&b. I do have an extra set of plans, too.

Thanks for the reply - Would you send me the excel spreedsheet and I would be willing to buy the set of plans from you.  I weigh 140 lbs so I will have to add some weight somewhere.



Thanks

OK to do your weight and balance put plane in the flying attitude with no 

fuel or people aboard and a scale under each wheel Left Main, Right Main,& Tail 

Wheel record these weights then hang a plumb bob line even with the very front 

of the nose cone and call that your Datum line and measure and record from 

that line to the center of your tail wheel ,mains ,fuel ,pilot ,passenger 

,parachute



The CG of a person is at the front of the stomach (navel)



add your total weights together 

add your total Datum measurments together this is your arm

weight times arm equals Moment 

Weight devied by moment equals CG in inches 



this should tell you where your CG is but I am not sure where it should be on 

a firestar 11 maybe someone else on the list can tell you the window of your 

model 

I hope this helps you

Ellery,  Thanks for the response.  I have done W & B on other planes but I 

did not know where the datum point was that was established by Kolb.  I got 

the  window percentages for the Firestar II from another member on the list. 

  Now I can get busy.



Thanks again

Galen

Their is "no" minumum pilot weight....but there's a CG range that needs



to be right.....Lighter the pilot....More weight in the nose.....



 "I" weight 200 lbs , "I" have 16lbs of dead weight in the nose....to get my



CG in the "front half " of the CG RANGE



 I'll move my Batt some day so I can get rid of "dead weight"



  I sent the Weight & balance figures to the list for you....



Gotta Fly...

You can use any point on your plane for the datum point  the math will always 

come out the same



do not archive
