バルブ数を増減させたい

エンジンの構造を説明するのにちょうど良いアプリ｡バルブ数を5バルブや3バルブに変更できるといいです｡上位版のRの方も設定出来ない感じです

1 Stern nur weiß keine null gibt

Sound kostet extra und bauen kannst du da gar nichts kannst dir nur schlechte Simulationen von Motoren Anhörens der größte Anteil der Bauteile fehlt

Very great but…

Hi there, I was wondering if you can allow us to have to more rotor configs as 1, 3, 5, 6, and 12 rotors exist, I was also wondering if you could let us have W engines, VR engines, and H engines along with U and X engines, I was also wondering if you could add tuning like turbos, superchargers, intakes, exhausts, and more! if the dev reads this, thanks

Please add them cause I wanna see more engines and engine mods :D

クラッシュどうにかして欲しい

自分でエンジンを作った際に保存するとそのままクラッシュして　もともと作っていたものなどの場合はクラッシュすると全て消えるのがとても迷惑です
