Sure, but why are you assuming RC planes don't use the chemistry improvements as they come out?

It’s a niche, small-volume market. I would be shocked if novel industrial battery chemistries are reaching it within even years of the frontier. (Less surprising would be small-batch novel chemistries. But these aren’t really comparable to the industrially-produced thing.)

We mostly use the same 18650 cells everyone else uses for everything, it's not like we're waiting for custom batteries.

		Again, the article specifically talks about improvements in car battery life since changes were made to tweak the chemistry (very likely in small dope ways). The fact that the article states that this appears to result in longer life and the fact that you talk about your RC plane batteries not having a longer life would suggest that the fine specifics of the two batteries may well differ.
