For people who don't want to install one of the servo mods, can't a microwave receiver be made which is just like a solar panelâ€â€just the back-side. That'd be a nice helpful tool. Maybe make it unlockable with the advanced electrics. The current way is basically plastering a pile of antennas on the fuselage or on girders. A retractable solar-panel-like microwave receiver would be like the moving phased-array transceiver, but with a larger and much easier reach (two panels for front and back with large tangent coverage) and the old antennae plastered on the sides. Also, the Heat Radiators have a model problem, causing some element of lag. They're probably the only part which I have issues withâ€â€the model used is too hard on the computer, probably due to its complexity. Simplifying the model would be really helpful. It is a good mod, great work! I like it, but there is a massive learning curve. While it is completely accurate (or at least, people say), I think some of it should be simplified in the same way that KSP itself is simplified from real rocketry.
