Just a few words...
I have been a very happy user of FSNav since I discovered it, and that was really the very best payware addon I purchased at these times.
When moving to FSX, I decided to purchase FSTramp, considering that even if the flightplanning ability was inactive, it was still a very useful addon to me, and also to provide some (financial) support to the developper, hoping that flightplanning was integrated again into the addon.
I later moved to P3D, and was still using FSTramp, basically as a moving map, a radar screen, a good way to check my navigational calculations, and also to follow my flights progress, autopilot being off or on.
Under FSX, and P3D, I have been using Plan-G for flight planning itself, but still prefered FSTramp as moving map or radar screen, as running inside the simulator, it was using less resources on my own PC than running the simulator + Plan-G.
When FSTramp v6 popped-up, my very personal choice was to buy this version to gain sufficient, not to say nearly complete, practice of this software. And my finding up to now is that this is really a very useful addon. But due to the new pricing policy, I only purchased a 1-year licence, hoping that with the time, the developper will come back to more reasonable price levels.
I can understand that we, the users, might be requested to give out some good money for each new major version (I did it for version 2.5, then for version 3.x, and will do it for version 4.x and following), but not for a time period only.
Not to be pessimistic, when a new version is out, you can purchase it. But if you pay for a given time period, are you sure there will still be a development team when your licence expires?
On the other hand, I can not understand that an argumentation is given on basics from the professional world, as flightsimming is not our job, it is only our leisure. And where I fully agree that hard work deserves a compensation, I actually find that a yearly fee in those ranges is not "within my budget". Being born in 1952, I expect to be a happy flightsimmer for many more years. And definetely, if the rates schedule has not improved, I will return to the FSTramp v5.6 + Plan-G combination when my v6 licence expires (unless some other good similar application has been released by an other developper, of course).
So, for the moment, I am on the learning curve with FSTramp v6 (my FSNav memories are too old), and just to mention a very precise questionning, being a VFR flyer on old roaring props, I use, and generate from time to time, flightplans where waypoints are where radials of two navaids are joining. (So far I have not reached the last page of FSTramp's help file, although this is on my daily "improve your knowledge" list)...
All the above being of course my own thoughts, opinions, decisions (right or not), and of course applying only to me
