Nope, planetary sounds even worse but I guess I'll have to try sooner or later... Is heat a problem with all the thruster firing? Or do you do it FAoff?
Fa on/off wont make a massive difference to heat generated though the gravitational pull will have a massive impact on how hot your ship is, the harder it's fought the more heat you will generate. However if you were to stop firing thrusters and let the ship drift (Provided you arent too close to the deck) you will cool down fairly rapily. Not sure on any concrete mathematics but smooth flight is paramount on anything above 1G.
