i actually have an idea. take the weight of the f15 irl, then divide it by the f15 weight in game, and use the same strength values for your plane. take the quotient and then divide the irl weight of ur plane by it, and then use that as the mass. if it worked for the f15 it should work for you. based on that it’s just a matter of tuning the strength value. at this point there is no consistency for my translations, i’m using gravity on the realistic setting, so your best bet is just to try that i guess.
