This mod works good in 4.12.2/SAS ModAct 5.30, but entries for SAS Engine Mod 2.6 (for 4.11.1) can't be used with SAS Engine Mod 2.7 (for 4.12), because CatapultPower/CatapultJetPower are not enough and planes crash during take off.
Pls find below entries for 4.12.2/SAS ModAct 5.30/SAS Engine Mod 2.7, which were found after tests.
