"Unfortunately structural engineering is not the strong suite of many of the ARF providers"

Exactly. My favorite was when Hangar 9 came out with the 1/4" thick aluminum landing gear that comes in 2 pieces and they have you bolt it to the 1/8 lite ply landing gear plate that is supposed to take all the moment loading from landing. ..But it packs nicely in a box. Which they have you keep for the pieces after the first hard landing. I guess they expected people to pitch it in favor of a one piece carbon/fiberglass gear.
