ATTN Simubuild

I've noticed with the -500's and -600's that looking back over the right wing to engine no. 3, that the fan is off centre, and instead of spinning like the rest, it osolates.Also is there any chance that a fan disc at high rpm could be worked into future updates as it looks very odd when the engine is running to see the individual discs.Anyhow, can't stay here too long, got to get back into the air with these great aircraft.AK
