Hi Jim,
I have just tried this by downloading from this forum, unzipping and running it, and it runs right through the program without bombing out. It all depends on the graphics card and the settings in your PC I think. The original resolution was 1024 x 768 if I remember correctly. Most modern graphics cards will run this program with ease. You can also try to run the clover from the keyboard before you hit the space bar by pressing the "C" key.
It is of course also possible that the download is corrupted, so just try doing it over. You can also try it on another PC as well.
There are a few funnies in the old program as well. There are a few glitches in the flight path of the model like the obvious one at the top of the vertical eight. I tell everyone that it's turbulence!
The tops of the square maneuvers are also as per the old FAI rules which called for "parallel to the ground". This was never flown that way because of the really short distance between the vertical legs and the much bigger corner radius. The extremely sharp corners have a 5 foot radius but there is no skidding as in real life. The latest rules do not call for 5 foot radius any more..........thank goodness. As I said, this was done in 200,4 so the old graphics are crude by today's standards. I have not had the time to do a modern update even though the latest software is incredible.....but so is the learning curve! Earlier this year I did a workshop in New Zealand with the latest graphics in high resolution but it did not have a flying model, just the maneuver shapes that can be viewed from any angle. It also has the correct square shapes as per the latest FAI rules.
Let me know how get on please. Thanks.
