| Post subject: | Spirit system setup - cyclic tunning question |
Hello, I have trex 450 with Spirit System and I'm just doing setup of my system... What I did so far - servo arms are more-less perpendicular to the shaft, swash is precisely leveled (for finetunning I was using subtrim from Spirit System app), blades pitch in neutral position is 0. Then I have used "Servo travel correction" and Collective pitch tunning from Spirit app to adjust similar collective pitch range (cca +- 11 degrees) up and down. Servo tralev correction is now more less set OK and I took care that all three cyclic servos have all the same upper and lower limits set. After that I have used the option Cyclic Ring (tunning) to set cyclic range (cca 8 degrees). The problem I can see now is the following: It's very strange that cyclic range changes as I move collective pitch up and down! It's cca 7 degrees in neutral, but it's cca 11 degrees when collective pitch is in lowest position and cca 3 degrees when collective pitch is in highest position. Please, any idea what did I do wrong in my setup and how to fix that? Thanks for your support, Denis |
