This was previously used for an RC vehicle or boat. I bought it used, for a project that I'm probably not going to finish.
Included are a Daehwa model DH 2T27R 27 MHz 2 channel controller, DH2 R27 2-channel receiver, 2 DH-86 actuators, and two sets of crystals, for 27.255 and 27.045 MHz.
The connectors for the actuators had been modified, before I got it.
