I agree that the Kolb Mark III will fly better with an aft CG.  I have flown it at 33% and 28%.  It gets busy at 33% in rough weather.  Does anyone know the CG limits?  I assume that it is around 25% to 31%.

16.5 FWD  23.1 AFT for Mark IIIC

tumultuous air will reveal weaknesses in balance better than any method.  A properly balanced airplane will

endure a sudden blast upwards with a nice straightforward  (level) attitude.  I have flown planes like that.

My MkIII is not so well blessed.   I'm speaking, obviously, of a column that uniformly boosts yer butt upward,

not a little dinky thing like ones that lift one wing independently.



Aside from any other problem with this is the necessity of messing with throttle settings too much.  I'm a lazy pilot

who prefers to just amble along and look out the winders.



What is the consensus?  do you end up with your nose down or up?

Here's a bit more detailed spread sheet built up from one offered by another lister (sorry, I don't remember who or I'd credit you)Happy New Year and lots of good flying in the coming year. Even you, JP :-}

Hi Robert,

How do you find those nice big, fat  smooth thermals that lift the whole 

plane on the level?.  I have found those condition in the middle of a 

thermal (sometimes) but I have usually had to go through the `one wing 

lifting` bit to get there.



Cheers

My Firestar II builders manual states that CG limits are between 20 and 35 % of wing chord.

Pat, if you fly low through the big hills south of here in the summertime you will definitely get more than one or two

big lifts.  You will be busy opening and closing the throttle to avoid overspeed, followed immediately by near stall

and cranking the stick like a butter churn.  Yes, I know, fly higher, but you have to start low to get there.



I experienced my first aileron flutter in those conditions three years ago.  Airspeed can leap to 90 in an instant.

Hi Robert,

I do the opposite.  On the theory that thermals start at ground level and 

dont start to build until they get a bit of height and are strongest at 

cloud base, I tend to go low.

I think we have different thermals here in the UK. Average say 3/4knots, a 

real stonker would be say 8/9knots wheras I have flown in Texas and the 

bastards seem to start at 10 knots and then build..



I have never throttled back in a thermal here unless I am trying to maintain 

a fixed height. If I hit a thermal I just pull back and stick a wing down if 

I feel lucky.



Amazing how we fly in a different style to `real` pilots. I took a `Red 

Arrows` (RAF airobatic team) for a ride in my Challenger. As usual my speed 

varied by a bout 10 knots and the height wandered up and down 50 ft. I 

offered mt passenger the stick and the speed and the height indicators just 

stopped moving as it they  had suddenly become stuck. I did feel amateur.



Cheers

Pat, you have a good point there.  If I maintain 30 ft above the ground the thermals should be mild.

Unfortunately where I was flying that absurdly boisterous day, the terrain was too vertical to allow.



I'm more a fair weather flyer now although I know one needs some bumpier air to keep your reactions up to par.
