...somethin' a little different, but neat...

Looks like a regular oval course set up. Notice this engine does not have the fairing on the back that the record setting motor did. Hu did set the oval course records with the R-22 and his Mark75H, but he wasn't that much faster than the super top dogs like Bud Wiget running a highly modified 4-60. I think the boat was probably very squirelly on ovals and the motor finnicky. A sucessive generation of Sid-Craft taildraggers obsoleted the Entrop/Jones and Michellini propriders on the ovals pretty quickly. A few years later, another generation of propriders appeared and again were obsoleted on ovals by improved taildraggers.
