The Multiples Royal EVO 12 is also worthy of consideration. All 12 channels are fully proportional, free TX software upgrades-downloadable from Multiplex, shift selectable TX so you can use it on any JR/Futaba PPM RX (not compatible with PCM RXs), synthesized TX module option available, and the Multiplex powerful programing....all in a more ergonomically friendly case (compared to the pizza box cases of the past). The EVO 12 Synth TX is available for almost half the cost for the 9ZAP/10SX equivalent and has 2+ more fully proportional channels than the JR/Fut. Take a look at the EVO before you put any money on the table.
