The above link will provide you with direct access to a collection of hitherto near-legendary documents - the set of "members only" model engine plans which was provided exclusively to new subscribers to the late Ron Chernich's frozen but still accessible "Model Engine News" (MEN) website. Ron and his fellow Motor Boys spent countless hours researching and developing these and many other plans and building engines from them to prove their accuracy.
It was Ron's stated intention to enhance his legacy by making the full Motor Boys plan portfolio freely available to all prior to his untimely demise in early 2014, but sadly his advancing illness prevented him from making this wish become a reality during his lifetime. It's a privilege to be a contributor to the final realization of Ron's wishes.
Our sincere thanks are due to ex Motor Boy Ken Croft for his generous provision of a copy of this hitherto elusive set of documents. And we're not done yet - plans are afoot to make the entire Motor Boys plan portfolio freely available through this website. Our collective debt to Ken and his former colleagues cannot be overstated. Enjoy!!
