I've obviously missed something important but what is REP?

 

REP stands for Reality Expansion Pack, from Simcoders. It gives an excellent (must have !) enhancement of some Carenado planes.

To be a bit more prcise:

The Reality Expansion packs replace the X-Plane engine logic. So you have to prime the engine if necessary, watch the temprature and pressure. You have to do an outside inspection before the flight. It replaces the aerdynamic model and enhances the flight characteristics. Sound effects are improved. They actively support their own headshake plug-in (freeware). They give warnings and advisories about the plane.

In general they become a totally different plane.

As an example the Car. Bonanza F33 and V35 have more or less the same charateristic. But eqip them with their REP plug-ins you see that the tail of the V35 isn´t as stable as the tail of the F33 9if the wind comes from the side. And you learn why many owners of this plane have equiped them with wing tip fuel tanks.  It improves the stability.

Thanks. It sounds interesting especially as I fly both the F33 and V35. Might give it a try.
