Spartan vortex vx1. Bert did a video on it too. If u have a v control radio then get a full size vbar . I’m pretty sure he did a vid on the vbar as well.
That's exactly what the video explains. Engines have an optimal RPM, this is why on 90 size machines the idea ratio for an OS engine is 8.2:1 allowing for a head speed of 1950 to 2050.
I find it funny that full scale pilots find it easier to fly first person rather than line of site like people that fly RC models do.🤣 If you don't do neither of these activities you probably wouldn't understand anyway.
