Thanks. What about a ST3000? Im currently trying to get rid of a Goldberg Ultimate and a guy is willing to trade me a ST3000 for it. Ive got it listed in trades and in the 2C engine section. I would really like an OS, Saito or a Moki for it though. Ive heard that you really cant beat the Moki thrust to weight ratio. I had a Saito 150 but I think the 300 would have been a little anemic with it. I had it on the Bipe.
