I did not install it. I helped dial it in on the first flight. I have to admit. Looking back the set up was never quite right ( or as other models ) As it is super sensitive to gain on elevator. I had to turn it right down in order to prevent it from oscillating in pitch. I should have really looked into the set up deeper. But I got so busy with setting up other 3e's and test flying various planes that I did not get round to it till it was too late and Kris had swapped the unit out. My fault. I should have looked into this set up deeper, but I got complacent as the other 15+ 3e's that I have helped fit and set up all went in and dialled in with ease and normally in just one flight. Also. Kris had set up his Eagle tree system that was in the YF22 before the 3e so well. I knew that he was proficient with gyro set ups. Sorry.
