JR XP783 - Using 'Crow' in Acro Mode
 

I have a JR XP783 R/C system that I am quite happy with.

I intend to get an Ultra Stick and use the Quad-Flap configuration, to perform the 'Crow'.

The manual only lists this function in 'Glider' mode and involves some mixing with the throttle stick (which operates the spoilers in a glider).
Is there anyone who has used this feature, to fly a normal, glow model in glider mode, with the left stick operating the throttle, as usual?

Am I overlooking anything?
