Just finished a session with Rob flying his EF 64 MXS with Cortex! Wow. I'm not what you would consider a gyro advocate but, well, um, as we say up in The Boston area when we want to complement something- it don't suck! Really fun. He had an off, mid and hi resolution set and I flew with low, what he called "normal 3d" (I'd say mid plus) and "insane" rates. First, gonna get an MXS! Second, the Cortex will easily make your experience better, it will stabilize your lines and make your plane feel a full class larger in the sky. It will make you ane feel a little more like a sim, dampening out the little corrections so you can concentrate on the maneuver you are learning. It will not take away any maneuverability and will let you perform insane XA. The only thing I noticed was some slight "hunting during KE in a gusty breeze.
Like I said, I'm not a gyro advocate but this one was a very enjoyable pull. Thanks a million Rob. If you are considering a gyro, this one is tiny, light, easy to operate and was a pleasure to fly.
