Hi Kirill,
Thanks for joining our forum and for your questions.
As for information regarding the approaching competitions - you can find it here:
http://www.rcauto.pl/modules.php?name=C ... age&pid=69 - unfortunately, everything is in Polish only... If you are particularly interested in taking part in any of those events or need translation - just ask. Using "Wyslij zgloszenie" form you can subscribe to the competitions.
You can also find a full calendar of events here:

As for rc class definitions - you can find them here:
http://www.rcauto.pl/modules.php?name=C ... page&pid=1 - unfortunately, similarly to all other information - everything is only in Polish... but again - if you need any help - feel free to ask us.
I am sure both electric and gas powered model competitors will be happy to see and race with you during competitions on all tracks in Poland.
