I know who you're dealing with at hobby-sports.com a.k.a. R&L Hobbies so deal directly with Rex or Lee, not any of those other morons there. there's only one person behind the counter that knows anything at all about boats and he doesn't know a hydroplane from a hydrofoil. The problem that you have is that rgeostat type of MSC's we just don't see around much anymore. The last one that I used was in the late `70's when I raced onroad cars with Judd Nichols and the gang, just when ESC's were starting to make the scene and Rider's was the latest LHS in town. They may have a good used ESC at R&L that you can pick up dirt cheap in their bins over in the corner by the nuts and bolts racks.
