Thank you very much! Great one, as always
I have a question about the throttle while doing the Cobra, it will no be more helpful to reduce the throttle and when the speed is right, to open it rapidly with the pull?

You may have to do that anyway depending on where you place the figure in your routine. The reason for doing so would be more a positioning and speed target rather than making the figure work better.
In this video the speed was correct because it was achieved during an acceleration phase coming from a lower speed. If approaching from a higher speed than required, I prefer to insert a figure that will achieve the same thing, thus retaining as much energy as possible.
Many show pilots do this figure in gournd effect right after take off. Thus they are at full throttle, with the engine developing maximum power and a lot of smoke ... in gound effect to get the best possible performance and be able to do it at a slower speed leading to less climb and shorter recovery. Any minor technical glitch will likely be fatal.
Either way, give your idea a try and report back. I'd love to hear about it.

@@NiccolaiMurphy Thank you! I put this figure right aft torque roll recovery and I tried to do it from 45 line and it felt good than I thought, I"ll try to do it on straight level and see how complicate it will be.
By saying retaining as much energy as possible - what do you mean?

Energy is required to keep flying. It consists of kinetic energy (proportional to the square of your velocity) and potential energy (proportional to your altitude). The engine adds energy to your system, maximum contribution is when at full throttle. The more that you can run your engine at full throttle, the better your energy state. Drag takes energy out of the system (your plane), high g takes more energy than low g.
You enter the box with a certain amount of energy. If you take care in the design of your sequence, you can maintain a high energy state throughout most of the sequence. If not, you will end up low and slow and have to break and climb to restart.
Gyroscopic figures require low speed, so put them after a figure that reduces your speed, so that you don't have to idle the engine to loose speed without exchanging it for something that will maintain or gain energy.

​@@NiccolaiMurphy Thank you very much for the detailed explanation! I'm learning a lot from videos
