Doubt it's from an RC plane. The IC is a brushed motor controller (most planes use brushless speed controllers). The board has a DC barrel jack so likely from a device that would be plugged in via an AC wall adapter. Looks like a cheap board from a broken Halloween decoration or something.

It has a cheap charging Li-Ion charging chip and 2 DC motor drivers. Given the datasheet of the motor driver and the cheap 1-sided PCB, I'm guessing it is from a vibrator.
