Santa dropped off a Goldberg Ultimate 10-300 kit, and I was planning on hangin a saito .91 on it. I have heard that the .91 would power it nicely, not overpowered, and i have also heard that it has awesome flight characteristics. Am building an A-10 now ( Model Airplane News Plans ) gonna tackle the Ultimate once I get the warthog wrapped up. Have to build somethin to smash in the spring ! Not sure what I'd do if there were no winter !! haha
