Sorry to hear of your misfortune but I gotta go with Ken on this one. Calling Hobbico to cry foul, would IMO, be a foul. Unfortunately that's all just part of what it takes on a dialy basis to keep these things in the air. When I'm not flying them in the daytime, I'm working on them at night. If you stop & think about the kind of rpm we run these things at, ANY screw vibrating itself loose is not un-common. We all need to get in the habit of checking & tightening any loose screws on a regular basis. Especially any & all screws on, in, or around the engine compartment.

Steady maintenance is as big a part of this hobby as the actual flying is. I try to do mine at night. I know I'm gonna fly in the morning so along with putting everything on the chargers tonight, I will also go over everything on the planes I plan to fly so that when I get to the field I know everything is ready to go.

When the sun comes up I'm already fueled up & range checked. Then I'm ready to fly as soon as it gets light enough to see. Try to get yourself in to a routine. It certainly doesn't have to be like mine but find one that works for you & you will spend your time at the field flying instead of tinkering with your planes. Good luck & I'm glad your plane only suffered minor damages, they are all easy quick fixes. Consider it an inexpensive lesson, it could have been much worse.
