Heavy handling on aircraft

[boeing247 0]

Is there anybody who has the freeware MiG-21 from migsim.ic.cz? Whenever I pull up on the stick, whether during takeoff or while in the air, the aircraft barely responds. It feels like it is going very slowly, but this happens even while at high speeds (I think I took it up to almost 500 KIAS and still had the problem). Apparently the MiG-21 was slow to respond on takeoff, but this is happening in the air, too. Also, I read that the default trim setting for the MigSim model is set to "diving", but I set a keystroke to adjust the trim up and nothing happened. Any ideas?

 

Thanks,

Edit: I was able to get the trim to work, but it's a pain to have to hope you've trimmed it just right, considering the plane itself doesn't have a trim wheel (at least not that I've found--the cockpit layout is different than American planes, of course). Is there a way to just center the trim or adjust something in the .air file or the aircraft.cfg?

What variable would the trim setting be under?

Is there no way?
