XP11 aircrafts with weather radar: A319/320/321 Toliss, B738 Zibo, E195 X-Crafts, C208 Thranda, SR22 Torquesim, etc. I don't believe it depends only on Laminar for Hot Start to put a WX on the CL650, if all other developers have put it on their products. There is no logic in this. But, if you have no interest in delivering a complete product, I believe it is a lost cause.
