RC technics,

Personally, i had the same problem with the snap`s , thinking about the P-09 program ( 1 1/4 snap down and 1 snap 45deg down )

This is what i did that changed everything to a crispy nice snap which i am happy about :

* As you already have done ; increase the aileron a quite amount

* Reduce the elevator to keep the track, specially in the 1 1/4 snap . Though, Keep just enough elevator to stall the entry.

* Increase the rudder, or at least keep the normal mode deflection. Yes, i was suprised about the rudder. "Normally", i have used less rudder, but this one is different ... without proper rudder deflection, it was impossible to manage anything near a snap ...

Just my personal setup.
