Test flown, Parameters adjusted slightly.

Changed some of the tunable variables, test flown in basic mode. All
working fine. I'm Impressed Oskar!
TODO: Diagnose loss of control experienced at full throttle
I ascended at full throttle while probably applying some pitch and roll
demands and suddenly the craft just seemed to loose stability.
It rolled/ pitched upside down a few times, luckily it recovered and I
was able to bring it  back safely.
However, have heard that a backer had a similar problem.
Possible causes are Yuan's Max throttle stuff, my roll angle
prioritisation (less likely as wasn't in the backers code), ROLL/ PITCH
SPL (spin limit). Or other!
