Hey, since you have kit building experience, use it. If you have a funny feeling about something, ask around, or do something about it.

Don't just trust the ARF builders, they get things wrong now and again. I've seen all kinds of goofy things come loose on ARF and RTF planes. For a while, one company (I honestly forgot which) had a reputation for the servo trays not being glued in very well. We had more than one work loose in the fuse, though in all cases the resulting control slop was noticed and no crashes resulted.

Also, may ARFS have firewalls that I'm sure are fine on paved runways with good pilots, but it's rather common to have the firewall or nosewheel mount tear out after too many hard, nose-first landings.

Now, I wouldn't go adding too much reinforcement with out finding out if your particular plane has a weakness in these areas. I honestly don't know about that one.
