At 9:49 You look stable and at that point you could have trimmed for correct aoa.
Then you turn left, you apply pitch input and get way low on speed. you correct speed and find yourself going up now, I'll bet you are cursing the hole way ;)
This hole trim for speed had me baffled for a long time, It is like eating with chop sticks if you don't know the technique :).
A couple of pointers:
1. You have to do a lot of things at the same time and be very upfront with inputs.
I see you loose speed and realize and then taking action. At this point you are just behind the jet and the best way is to clean up and do it all over.
2. On speed: It's a bit unnatural if you ask me and you do the classic thing when low on speed ...pull the nose up and then throttle up. Reverse that and just don't get so low on speed. If she beeps at ya, then you are about 4-5 seconds too late in your inputs.
Also, when on speed, no pitch movement is required or very very little (diamond almost don't leave the center on the lower left control input screen). When i bank to 30 degrees ,the throttle controls the pitch and I have to stop the roll with a tiny bit of counter roll. So tiny right stick and throttle stick to control pitch. Lex made a very good video on this.
So to sum up, you really have to be "on it" and it takes practice. In time you will also develop the skill to hear where you are and crosscheck your parameters. Once u get the hang of it, your workload decrease by 70%, because now you feel comfortable with what you are doing :)
