My understanding is that in order to get the LongRanger IFR certified, it needed the fins on the horizontal stab. (There actually were some that were certified for IFR).

Highlights the problems with civil performance charts - they only give 'hover capability' and not power required to hover vs. height AGL like the military charts do.

John:
You would be surprised at how much effect things behind a static port can have.
SASless is right - we don't really care about what happens as we're flying VFR, and it may make a smidgen of...

Regarding static ports - they are indeed just ahead of the doors, and I seem to remember it made about 100' difference in pressure altitude in the cruise from doors on.
Next time you fly with the...

I don't know what might cause the negative static stability - the effect of the airflow on the horizontal stab sounds plausible.
The point is that there is no such thing as 'control reversal', and...

SASless - yes we then increase the collective to get more power, and on descent before landing, since we're already decreasing torque before we beep up, there is no danger of overtorquing.

Most of what was said in the original post is difficult to follow, it must be said.
Power is torque times rotor RPM (with a constant thrown in to do the coversions).

We have a C20B that is very slow between 50 and 58% on the first start of the day. I had also seen this many years ago on a 206 operated at the Bell factory (who did everything they could to find the...

Not sure that an STC is needed - it doesn't interfere with the flight controls, change the performance or handling, and doesn't affect the electrical system. In the US, a form 337 would suffice, I'm...

The reason for the RH seat only limitation was a crash in the early to mid 80s where the LH seat pilot had the cyclic come off in his hand because it was not put in properly. Not sure of the outcome...

Just out of curiousity, what condition were the rotor blades? Old, new, pitted, etc? The engine might well be above spec, but if the blades aren't working well you won't get the...
