Love this mod, but I noticed several issues with 5.3 and the stock engine config. - Nuclear engines have an ISP of 1000 when used with H2, but you get VERY little delta-v out of it compared to other engines. There seems to be something seriously off with these. Also, although they are quite similar, their weights GREATLY differ. - There is no fuel selection dialog for RCS thrusters and they will only use the generic "MonoPropellant". Any other fuel, even if in a tank the thruster is directly attached to, will be ignored. - Only Kerosene, MMH and LiqH2 are used, other fuels cannot be selected for any engine. And for jet engines, there is only jet fuel. - Under some conditions, there are some ugly line wraps in the fuel selection window which will introduce an annoying scroll bar. - When moving/copying symmetrical tanks it may result in only one of them containing any fuel. This is especially true for jet tanks, in the plane hangar and when grabbing a part the tank is attached to instead of the tank itself. Any chance of these getting fixed in 6.0? Cheers!
