I have always used the the Futuaba GY 401 on my Vectored thrust Eurosports with good effect. I am just waiting for my P200 Vectored thrust Futura to come out of the vinyl shop before I fly it next week I hope. I am going with no Gyros on that one as I have a feeling it wont really be a hovering type jet. I have the vectoring more for the tumbles, and for this you need zero gyro.. I could be wrong mind so may end up retro fitting a gyro or two.
