This is a Multiplex Cockpit SX 7-channel computer transmitter, with an integrated Jeti Duplex 2.4GHz transmitter module. The integration is very neat and clean, and looks like a factory install.
The battery has also been upgraded (from the original NiMH) to low-self-discharge and long-life two-cell lithium Li-Mn cells.
Makes a great trainer box for your main Jeti radio, or as a super lightweight standalone Jeti transmitter. I used it for flying discuss launch gliders (DLG's) where the light weight was invaluable.
Tx is in clean condition, batteries are excellent. The Jeti TU2 tx module alone costs more than $190 from the Australian distributors (Modelflight), so you're basically getting the transmitter with module for less than the module itself.
Includes a nice protective case, and a quick start programming guide. I can include the original A4 hardcopy manual also at no charge. Happy for pickup from Brisbane western suburbs, or will post Australia wide at buyers expense.
