congrats and welcome to the addiction.......errrrrr hobby i mean. as for the repair, everyone's right, it isn't that bad, heck my first "mishap" resulted in my avistar being brought home in a plastic walmart bag, i built it back and she still flies today!! but if you don't want to bother with repairing the firewall, stick a piece of wood in the hole to keep anything from getting in and convert it into a taildragger. best thing i ever did to my trainer.
