Hydraulic "Transparancy"?

The smaller blades on the B are the problem (blue for the B and D grey for all the rest). The hydraulic systems are all the same from the pump to the servos. It seems that the smaller blades have a harder time with the forces and transfer it to the servos. Get up to altitude in a loaded B and you''ll feel some feedback at 80kts. The grey blades are a good start getting rid of the problem.
 
I believe they tried 2 minutes and found that, while there is a difference between 2 minutes and 30 seconds, it wasn''t worth the wait, and in some cases could be detrimental to the engine. The Allison, of course, is squished back on itself, so would have more hotspots which need stabilising.

The D model Astar needs 3 minutes

Thank you, that explains that, and also If I ever experience it, I Won''t mention it to the CAA/TC/FAA or whoever, Just mark it in the book as being not smooth enough. As an aside, an ASTAR plunged today in Norway, but apparently the pilot walked away, even if the airframe apparently was not too pretty!

Second Question, How come the 206 and most other machines have a 2 minute cooldown, when the french machines seems to have "no more" than 30 seconds??

Have me beat for sure! Well again, thanks for all replies

Hey, Mr. Albert Ross....how''s your summer shaping up?

While we''re on the topic of hydraulics...what does a bad servo feel like in a Jetranger? Mine seems to have a lateral issue where the cyclic "feels" like it reaches it''s stop, then, with added input, will achieve more! Feels "soggy", for the lack of better phraseology!

Hey Chevy 2, I know exactly what you are feeling (no, I'm not a psychologist either

It could be one of 2 things, check ALL the bearings under the seat(co-pilot side as well as pilot) if it's different laterally Vs fore and aft....or check the tension on all of those nifly little bearings on the mixing unit at the bottom of the "broom closet".
The tension must be exact,and even.... on those 3 little doo-dads.
We just went through the same situation here.

OK I just re-read your initial post....I bet it''s a stiff bearing under the pilot or co-pilot seat....

Well...you were exactly right! The teflon thingy on one of those little "doo-dads" was worn due to improper tension.
