RE: Goldberg Ultimate 10-300 build
Rideblue......................the sound of a 4 stroke is what will change your mind. I just love 4 stroke engines, it's just my opionion. I got back to this hobby four years or so ago after a long, long spell and I only had two OS engines 2 strokes glow. After my few months on a trainer with a two stroke, I completly switched to 4 stroke and have never looked back to the noisy critters, don't care if they have more RPMs, to me the 4 strokes is the ultimate. You'll need a 4 stroke in the Ultimate and you'll enjoy it.
Good luck with your building of the kit.
