Microsoft Flight Simulator (2020) - We're really sorry about Microsoft Flight

I made the mistake of clicking around the management screens in FSEconomy and now I’m the proud owner of Serenity Now! Aviation, with a string of 5 small FBOs in between Utah and New Mexico. Out of the five, only one had an ICAO recognised in MSFS, so I’ve been landing on rough ground, taking on passengers, and heading off again. Some of the folks on the forums are creating landing strips for me (one done so far) so I don’t smash my undercarraige.

Taking off in the DA62… the dashboard says that I should be hitting 136 KIAs on takeoff, but I think I’d need a 10,000 foot runway to manage that. Is there some trick I’m missing, as it’s a bit of a struggle to gain altitude after takeoff in a stable manner.
