About to fly my 7-year project. I have taxied some and I find a hand full to control. Directional control is quite sensitive. I do not have a locking tail wheel. Should I? I show about 1 degree toe in total. Is that acceptable? I have the spring type connector for tail wheel steering (Vans set-up). How much slack should I have? Any discussion, suggestions appreciated. I have about 550 hours in a RV-7, this is a different level for sure.
