Steve, I have both bellcranks in front of me and I have good news. To use the ball bearing unit all you need to do is open the holes on the fuselage sides approx. 1/8" and the unit will drop right in. The end plate screws are even the same pattern as the original bellcrank and will match up to the existing screw holes in the fuselage.
I am still curious why no discussion about this aircraft here at RCU, even after more than 8 weeks have passed since it was released. I am guessing that the hefty prices Goldberg is putting on their ARF's may be pushing customers to other brands.
Does anybody have a Matrix in the air yet? Feedback???
I plan on using a .70 Surpass Ultimate on mine so I can take advantage of the built in fuel pump.
