I just bought a goldberg ultimate 10-300 what I was wondering is if any of you have put it together with just the hardware that comes with the arf,it came with carbonfiber rod with split metal ends that go inside the rod this is for the elevator, and what servo for elevator and rudder,any advise would be helpful thanks

I use a pull-pull system on the rudder and a dave patrick pushrod for the elevator with 4-40 wires. I run a Magnum 120 4-stroke on it, but I've heard that guys have gone larger yet....

I use Hitec 615MG servos all the way around. I also set mine up to use twin aileron servos with a direct 90 degree setup from my servo horn to the control horn on the ailerons. I found out in flight that the bellcranks do not work well and causes a great loss of control. I got it down okay but man, I'd sure hate to try that again.

I built one some time ago....I am using an YS-91 AC with a Zinger 14 x 6-10 prop, JR System
JR 531 Servo's.... Rudder push pull, Elevator with the supplied pushrods..Y type..seem to work just fine, Ailerons (2) JR 531's....Using a Slimeline Pitts type muffler. The wing struts are held together with 4-40 cap bolts and blind nuts. The model balanced right on the mark, the plane flies very well nothing unpredictable.[8D]
