Picked up this undrilled hull earlier this winter from a guy in Florida.
Surprisingly these hulls are still being built by Lenny Blake of "Rum Racing" in Arizona. Original designer and manufacturer was Calvin Motley, thus the name of this hull
Anyways ... having raced smaller sizes of this exact hull back in the mid 1990's, they were top runners and solid performers. This hull the Big nitro/Gas version at 44" OAL. Hope it runs as well and have rigged it with a blend of mix & match hardware to duplicate close as modernly possible the rigging used 15 years ago.

Powered by an RCMK Evo engine tho using a modified 1st generation cylinder, ceramic coat hot pipe combo. Long trim tabs, Top secret stinger drive & rudder, home made turn fin, CC t-bar & homemade wood radio box. Hi-tec servos with Futaba radio gear. Bucks bag I.V. fuel bladder attached to stringers forward of engine.

Nice job Scott. Should go well as well as handle well (well,well,well) Just goes to show that when you love those earlier boats, you always at some time want to rekindle the fun. I did this a couple of years ago with an early hydro called "WHITE HEAT" circa 1970. You have just got to love those early hulls.

That's a nice ride! I remember those boats too...at one time it was the CalCrafts, the Youngbloods and the Twincrafts!

Gosh you see so many new designs, but then you have such a clean classic set up and it makes me want one. Where did you get that cool muuffler? Curious, with trim tabs, they are set up one farther from the center of the transom than the other that is tucked under the rudder support. Why?

Tabs are evenly spaced, an optical delusion
Spacing of tabs is the same having an @ 2 3/4" gap for prop to find clean water.
Rudder @ 2 1/4" right of C/L
