I personally don't have a problem with iteither way,...It was just a "brain tickler" for awareness in reference to safety (I had a ST-2500 that would do that all the time,..makes you say bad words when it happens,..LOL).
On my Airtronics Stylus I used, I had the throttle saftey programmed if the throttle was at full open the plane (receiver) would not engage until the throttle position was lowered to the idle position,...good safety feature. I have no idea if my 9Zap will do it or not?
I know the current set-up being used is working very well on 2.4,...what about 72mhz?
