I purchased the Paramotor for P3Dv2 and used it fine in v3. I've now got it installed in P3Dv4.4 and it still works perfectly. This thing is a gas! Low and slow(15mph) is a great way to see sceneries, especially ORBX and their Easter eggs. If an airport looks half way interesting after landing, I usually switch to the Paramotor for a tour, and see things I never would have seen just using an avatar guy. Very good bang for the buck.
Accuracy and ease of use gives FSGRW five stars. It takes about 15 minutes to go through the 10 page manual and set up FSGRW. Once set up, all you need to do is click one icon, and off you go. I've used REX, AS 2012 and Opus, and of the four engines FSGRW is the most accurate depiction of weather of the four and the easiest to use.
Have had FSGRW over a month now. I use it exclusively, with REX textures, instead of the weather engines in REX, AS2012 or OPUS. It is very simple to operate (ten page instructions in large type without pictures), doesn't change the FSX registry, and IMHO is the most realistic of the four weather engines in that it mimics actual weather conditions very closely. In almost daily use, I have yet to encounter any cloud pops or abrupt changes in weather or winds. Once set up (10 minutes max) all you need do is click one icon and forget about it. There is absolutely no thinking required, which for me is a real plus for FSX addons.
On a par with Aerosoft's PBY Catalina for detail and "look." If you don't follow the manual, the engine can overheat, encounter power loss, etc., so it's definately by the book. There's a US livery, with English labeled controls, which is the easiest to learn, but still has kilometers per hour and an altimeter in meters--a definate challenge. As for instrumentation, there's an ADF, but no GPS for those of us used to flying the magenta line. Great aircraft to use with with VFR flight planners, such as Plan-G. Try navigating the Wilga in the mountains of NZ!
