Awesome, finally out However, i'm not playing with Realism Overhaul and real solar system, so i want to use real fuels, but with stock engine and tank masses. When using the stockalikes engines config the engines are a lot lighter than in the stock game, the mainsail is 1.875t instead of stock 6t for example. And i don't see any engines that can use any other fuels than LOx/liquidfuel, LOx/LH2 and MMH/N2O4, though i can still fill the tanks with any fuel i want. Maybe i've done something wrong, or have i just misunderstood what the stockalikes config is supposed to do? Regardless, awesome work
