this is a patent for the “whirly bird” after making a few they were sued by eli bridge for patent infringment. it was driven by gears the same way as a scrambler. jerry wisdom purchaced the idea and changing it to rim drive/hydraulic.
wisdom didnt invent the gravitron either they stole the idea from someone else. the original gravitron was covered in canvas and had aliens painted on it and was in san antonio texas fair in the ealy 80s.
wisdom also stole the single trailer himalaya idea from david brewer in 88. they didnt invent the raiders either they purchaced it from jules catarzi
