The plane is broken completely… and there are so many other things broken in the career mode, that the player just has to repeatedly “grind” missions to get their money back after selling the aircraft that simply do not work.
It would be a good decision to have some more QoL features, like selling new or almost new planes back at 99% of the money, not at 75%… or transfering viable planes between companies… even if there were no bugs at all. But with the extreme amount of progression breaking bugs, its absolutely necessary.
I first managed to get (after the LONG time spent with Cessna sightseeing) the Vision jet. It works perfectly, very happy. Then the Cessna Grand Caravan, which works less perfectly, but its functional… but when I got to the properly interesting tier, stuff broke down - I bought the Pilatus for Medevac missions… there is not a single medevac mission for the Pilatus. And because we cant tranfser the plane, I had to sell it, undoing several missions of progress worth of credits.
So I bought the Medevac Grand Caravan… and had to sell it because the payout for the MORE ADVANCED medevac missions is 3x lower than for a shorter medium cargo mission. Another loss of several missions worth of progress.
And then I bought this thing - the ES-30 … and its broken completely. It cannot fly to its target without losing the engines, I managed to restart them once, then they died again, then the main engines died to. I restarted them. They died. On 4 separate missions I had this problem. Both when skipping to descent and when not skipping at all. And only in one case was I able to restart the engines for long enough, to drop the landing gear (which has no emergency release and need electricity, which is only up when the engines 2 and 3 are up) and to keep the main engines running long enough afterwards to make it to the runway (which is hard, because both main engines running cant even keep the plane level with gear down)
And this one will be at least 10 missions worth of progress loss upon selling it.
Very disappointing how the amount of bugs and unfriendly design of the progression makes the career mode extremely frustrating, even when the player tries to use every workaround possible.
