RE: twin engines should use a gyro rudder??????
Go to warbirds.com in the techniques section and look for twinmans reports. He talks about gyros in his third section I think. If you serch on twinman here you might find a thread that explains how he did it. I believe on one of his twins he used a gyro on rudder and another gyro on ailerons. Think it was the P-38. In a nutshell, all it does is give you more time to react in a worst case scenario. Which CAN make the difference.
