Hey guys, recently purchased a shovel nose hydroplane hull for an electric build and noticed the runners aren't completely flat like what is typically seen (or at least what I typically see when looking at these types of hulls ..I am rather new to rc boats, tho). This hull has these skinny rail type runners and I was just curious if there's any pros/cons to this design vs. flat runners, or if it's meant for a specific type of setup/build, like maybe it's an older gas hull design or something, or just an older design in general. Any info/thoughts on the differences between the two styles would be greatly appreciated. I'm just curious! I haven't received it yet, but these are some pics from seller. Red hull has the rail type runners, white hull shown with flat runners for comparison ..also curious if the wood rails laying inside the hull in first pic are a sign that this hull was originally intended for gas use (not that I care, just curious) - is that what they are typically used in? (gas boats) Thanks!
