Cuban8 Posted December 24, 2021 Share Posted December 24, 2021 I had an Anniversary Goldberg Cub many years ago and for some strange reason I sold it on. It was a lovely model and I regret getting rid of it now. I do recall that the model flew much better and was more responsive with the CG towards the rearward setting so I wouldn't go for 25% but start at 30% and adjust to taste but with not too much elevator movement. The model wasn't what you might call a 'floater' it didn't like to be dragged in too slow on approach but needed to be flown right down to touch down or things could get messy. A lovely model that'll fly in most conditions so I think you'll enjoy it. Quote Link to comment Share on other sites More sharing options...

andy paterson Posted December 24, 2021 Author Share Posted December 24, 2021 I have found that the Anniversary Piper cub is the same spec and C of G is 3 1/2" to 4 1/4" from leading edge Thanks all Quote Link to comment Share on other sites More sharing options...
