First time poster. My D20A-6 "Squalls" when I tilt the blade left, but does not do that any other direction. Could that be a restriction somewhere, wrong Hydraulic Fluid (oil) in it, or? I also wanted to thank everyone for the wealth of information they have contributed here. Took me 4 days to get thru all 118 pages and I was so involved in it that I was disappointed when I got to the end. Special thanks to Larry as he is the one that inspired me to get a D20A in the first place!!
