RE: goldberg matrix
I'm about 90% done "building" mine and so far it's gone together pretty smoothly. This is the first ARF I'm built so I can't compare it to others. The only thing I'm stuck with now if figuring a way to secure the fuel tank. I have it back on the leading edge of the wing and need to find a way to keep it from sliding forward and back. I'll be using a YS 63 on mine so I don't need the tank up in the nose. Should have a flight by next weekend.
