| I have just rebuilt my (second-hand) Ergo 46 CCPM and am having a few problems with the pitch set-up. The model uses a one-piece molded link for the short linkage between blade holders and mixer arm, so that part is non-adjustable.
I found that if I set the linkages acording to the book, I have a pitch range of about zero to +20 degrees. I therefore shortened the link between swahplate and mixer arm, so now have -6 to about 19 degrees, but the mixer arms are not level for a hover of around 5 degrees. Nor can I get anywhere near having the arms level and zero pitch. I have settled for the arms off-centre and a mid stick hover of +5 degrees, but isn't there a simple way set up the Ergo? I am trying to get a general pitch curve for sports flying with some aerobatics, not a wild 3D set-up. I am not a complete beginner, I've flown helis for three years and set up my own and others' helis many times, but this one is a bit confusing!
Any advice form other Ergo CCPM owners gratefully received.
