If that were true we would never had to have a BR6000. It was made particularly at the request of roboteers (that is why it is called BOT Receiver) to have a programmable failsafe on all channels.

Let him demonstrate it, because it doesn't work. Only the throttle channel has a programmable failsafe, the rest stays in position. Your salesman/vendor confuses the power-up position (which is programmable) with the failsafe position.

This is from the AR6200 manual:

The AR6200 features a SmartSafe„ failsafe option. SmartSafe is ideal for most types of electric aircraft and is also recommended for most types of gas and glow-powered models. With SmartSafe, when signal is lost the throttle channel only is driven to its preset failsafe position (normally low throttle) while all other channels hold last command.
