RE: Goldberg Extra 300
Using the delfection gauge provided gave too much elevator throw for my liking, and after a bit of adjustment I ended up with 9/16" of travel in both directions on the elevators and 3/4" on the ailerons on high rates and all the rudder I could get. On all these I use 30% expo. and the model flies like a charm and is more than capable doing the IMAC sequence.
