It happened so quickly and was a long way down wind that its hard to tell if the turbine shutdown or not.
I am going to go with Powerbox Royals 9 With the inbuilt twin RX's ) On all my jest from now on, powered by twin Lipo. A tough lesson learned!
Ron Long! Sensitive side?? Are you joking V

I will open up my RX tonight and have a look. I really hope its not that!
As for the twin RX thing... On all of my models over 20KG ( 44 lbs ) I have to use twin RX's ( Uk AMA/FAA Rules ) I have 4 models like this currently with no issues. I just bind one at a time, and its all good.
The C-17 Actually has 5 Spektrum RX's in one plane bound to the same RX
Ron... Strange way of asking. But now you are setting the Mig 21 up on Futaba. What are you doing with the MX-22 Radio?
