I discovered nose gear slop with the trike trainer as the .025 push rod was too small to be sufficiently held captive by the servo EZ connector. I changed the push rod to .073 and it now is solid with no more slop. Hammer head stalls are no problem but the skid with rudder and opposite aileron I have not tried yet. I will try that on my GP basic simulator first. A gyro in the rudder, Wow! that is something new and maybe something to consider in the future. The transmitters used are both Futaba 72mhz with a model 6A used on the tail dragger trainer Skyraider and a 6H used on the trike trainer Skyraider and the 4 star 60 low wing. Funny thing happened today as I took the tail dragger trainer flying. Before flying it, I went over all I wanted to do differently as use the rudder to straighten the take-off...etc but then the plane took off straight with no correcting rudder applied and then I went to land it in a 90 degree cross wind and planed the used of the rudder again but it came in straight without any rudder application.....Oh well! even the little weak tail wheel worked perfectly. However, I am going to develop the rudder skills. Thanks!
