a bit like Bell blaming LTE for a TR that was too small for the job.

That is an excellent way to describe it. I’ll remember it when next I am confronted with an LTE “expert”


The Bell 47 G5, when fitted with a 'Texas' No bar Kit, would exhibit feedback forces on the lateral Power cyl when one rolled and turned fairly quickly to starboard. The thing is the lightweight Rotor system was much more manoeuvrable with the No Bar kit and a careless quick turn right would result in a high pucker factor when one decided – fairly quickly I might add- to come right side up.



It was no big deal really, just like flying with hydraulics off but loaded up also, it was however; ONCE ENCOUNTERTED – ALWAYS RESPECTED.

It was a situation that was always amplified with worn power cyl trunnion bushes. I practised hyd-off landings with much worn bushes once, with the Texas kit installed, very spooky!

I did have a pilot once though who thought that the feedback was the result of an out of adjustment irreversible valve spring adjustment. Until I heard about it that is. That really did frighten me.
