Ok i will try that.I get the funds thing. But we are talking about a nessisary tool in actually making the sim work. Borrow one or fined one at a agarage sale or whatever. Even having one for a short time you cane make your own beam scale to use later. Just guessing when trying for extreme performance is sloppy.
But i havnt launched yet due to extremely high winds recently. I think wind gusts were about 40-50 km/h.
