Spirit System

Yes , I think (I don't fly with them) but I can't change anything...just demo mode on the mac and pc ...

Are you sure you are starting the software after initialization?
There is no difference between these versions in this matter.

yes..I can't reflash the spirit, because no recognize. I don't know what to do. I have 2 heli like that.

Please check the usb interface wires. It looks like something is broken there.

Please try second usb interface.

no blue light on the usb interface when the heli is ready. but this same usb interface is ok with an other heli. I just controled.

OK it's the interface. It's strange because the first one is ok on my oxy3 and not on my forza 450EX. I just take an other usb interface, absolutely new, and now, miracle my forza is recognize !!!
So it's OK for me...I have an other heli in 2.0.1, I can directly go to 2.4.2 ?

Perfect. Yes, this is really strange.

You can update directly, I recommend on the same computer as previously.

Thank's a lot !! Awesome fbl system with awesome service.
