Chibita gets into R/C model planes after seeing the sextuplets' new expensive R/C bomber. But when he's barred from the model shop and has to pay Osomatsu to play with theirs, Iyami helps him make his own fun, leading to the sextuplets' plane breaking. When the kids chuck out something as expensive as what they had, Iyami repurposes it into a new way for Chibita to get his revenge.
