Carl Goldberg Extra 300 balance question
I replaced the OS .91 Surpass on My Goldberg Extra with a Webra 1.20. I've added just over 4 ozs of weight to the tail, and it still balances nose heavy. So far, I have flown it once at about 4-3/4", and it flies terrible there compared to how it used to fly, although it's no longer under powered.
What is a good balance point for this aircraft?
