It's just a simple matter of checking the data screen for which model is selected. I've made that mistake before, it no big deal except I went through a lot of work for nothing. On the up side, The motor, pinion, belt system all got a good look over (LOL). The simulators, I know they're getting better but they are not there yet as far as realism, so I'm not gonna make the plunge till they are over 85% accurate in visual and reactions. Dunno....I'm like that. I can hover nose in on a sim, can't do it in real life....very irritating (LOL).
