Well she's small, because she's meant to be a "toy" robot.
The original project was to build an avatar based loosely on a "Medabot". Medabots, for those who don't know, was "yet another pocket monsters (Pokemon) show." But the series was made as a PARODY of it's own genre. Kids who have robots, battlling other for supremacy.. with utterly ridiculous villains, and a magical referee who seems to be able to appear INSTANTLY whenever ANY challenge is declared, and everything.
Anyways, they're sold in toy stores, and are basically "Collectable fighting dolls" with AI's and interchangable (tradable) parts.
Even though the F-Type isn't a medabot, a lot of my marketing actually reflects that idea.. selling "parts" and a "base robot kit". Clearly though, the F-Type has evolved beyond the likes of Metabee, Peppercat, and NeutraNurse. The Rubber-Robo Gang wouldn't stand a chance against her.
The fact that so many people are modding her right out of the box... well it makes me smile.
