[1.4.2 - 1.7.3, 1.8.1-1.9.1] KSP Interstellar Extended 1.25.20 Support Thread in Add-on Discussions Posted September 2, 2019 Hi I'm wondering how I can make a radiator / engine heat work well with this mod. My issue is coming from a multi mode engine that I'm modding. Out of atmosphere radiators anywhere on the craft are able to deal with excess core heat that the engines produce. But while in atmosphere I've only ever been able to get radiators that are surface attached to the engine being able to handle the core heat from the engine. And even when I do use them the radiators still explode in atmosphere at high air speeds even though the radiators should be far more than able to handle the thermal load even without the convection bonus that they get while in atmosphere.
