I built several models with Goldberg retracts, but never got to "field test" any of them. Something always came up that diverted me from modeling, so I sold them, unflown. Never heard any complaints from the buyers, but I wasn't exactly in a position to either.

I understand that the Goldberg retracts went through several improvement phases over the years, with the final product being very good retracts. You did have to be a bit of a mechanical genius in order to get along with them, but I'm sure you never had a problem like that at all. What most of us did have problems with were the fixed position, non proportional retract servos.
