Thanks, that's indeed helpful.

I note that the lowest rpm shown is around 2650 rpm if you extrapolate the graph to SL. This is obviously the high pitch setting, I wonder how much rpm should we see from low pitch at SL? The planes in game currently show a lot lower rpm in fixed high pitch, for what ever reason? The issue that results is that hp is linked to rpm and thus the planes in game with fixed props may be under represented in this area if rpm is low.

Virtual props in Targetware were difficult animals to get functioning realistically, I imagine it is the same here in IL2 FMs.

Thanks again for the data.
