rayspan, yes with nearly 60 fps on my machine fms is far from stuttering. Many models are a bit unrealistic fast, yes.
But that depends more on the settings in the .par-file than on the fps...
I've seen models with 80N-thust and all drag-coefficients set to Zero (or nearly Zero)!!! Flying more than 250m/s. That is crap! :angry:
I think many model-builder just make it easy and copy .par-files from other models without adjusting it to the real RC-model. This is sad.
