Is it mandatory to have the same flight plan created in FSBuid or FSCommander etc, be activated in the flight planner menu of FS2004? Or is the RCv4 flight plan sufficient? Then I suppose by listening into the RCv4 heading info and adjusting the headings accordingly the plan can be also flown right? Or has this Plan got to be in the default FS2004 active plan???Would this cause CTDs ???

>>Is it mandatory to have the same flight plan created in FSBuid or FSCommander etc, be activated in the flight planner menu of FS2004? No it isn't. RC does not require a plan to be loaded onto FS to function. Obviously, if you wanted to use the FS GPS as your navigation system (or for example, the feelThere B737 FMC)you would have to load the plan to FS as well but RC functions entirely separately from these or any other nav systems.Pete
