I love it when someone not only had an interesting idea well before me, but actually implemented it!

Just eyeballing the video, it looked like you were getting ~10 degrees of plume deflection there. Is there any more information available about the hardware setup, where you were injecting the TVC fluid, what amounts, what results?

LITVC is easier than one might think, and Nitrous works really, really well (approaching N2O4 in effective ISP as measured by this subscale test using load cells to measure side force generated to calibrate how much N2O needs to be injected to achieve a given thrust vector angle)
