380/420 dfc made easy with tbr links/armswhat I did was convert my 420 to dfc two blade by using the tri blade control links and grip arms x2. Removed the swash drivers and that was that, 2 blade dfc made easy as ever and didn't go aftermarket either. I suppose lynx or alz or sab will all do the same thing. My perticular problem has always been getting the swash and control link back to 80° phase lag. When you ever have the chance to experience 80° phase lag be sure to come here and state your thoughts. I have a 450 where I advanced the lower swash 10°, flew it a few days ago and was incredible how it stays put where you want it, no confusing biases to overcome.380/420 dfc made that easy.
