This drive hub for APC props and Cox perfectly centers APC props without spacer rings on Cox .049 engines.
Fits reed and Tee Dee Cox engines and APC props with 5/16″ (7.94mm) recesses.
In development we found some APC LP06040 6×4 have a smaller recess and will not fit. APC assured us these were older production.
Made in the USA!
