I just use the default FSX flight planner to create a VFR VOR to VOR plan.
I then go in and either add, remove or change VORs depending upon waypoint
leg distances and terrain, etc.
Once I have a plan I like I jot down the VORs in order with Frequencies and track to
that VOR from the previous one.
I then save the plan, then when I enter the cockpit I use the FSUIPC 'Load plan' feature.
I then open the FSX Weather map and adjust the wind, clouds, temps, etc
along the route as I desire. I don't use 3rd party weather engines as a rule although I
have REX and AS2012.
Once the weather is set, I'm ready to start loading and boarding.
This method helps me to get rid of all the blank or partially blank pages
that arrive daily in my mail with my bills!
I have a stack of 3 or 4"
by 11 1/2" 'strips' for putting my flight plans on .
