About the 3rd Edition (with raised cabin height)

STOL CH 750 builders and owners do not need to update to the 3rd edition drawings, unless wanting to increase the cabin height.

Click here to view a list of the parts for increased cabin height (changes from 2nd Edition to the 3rd Edition).

Now available: STOL CH 750 Curved Cabin Top (3rd Edition) Kit.  This kit  is for current customers wanting to update their existing kit (Edition 1 or 2) and includes the parts changes.  Kit includes the 3rd edition drawings (same serial number as your current)

These parts for the raised cabin are fairly bulky and delicate since they include a new welded cabin frame assembly and new formed windshield and new formed top window.

Since the taller cabin features are now standard with new kits, we cannot accept exchanges or returns of Edition 2 (or earlier) parts (such as the welded cabin frame or formed windshield).  However, we are working on a drawing to help builders modify their existing cabin frame to take full advantage of the raised cabin.

About the 2nd Edition (with design gross weight increase):

STOL CH 750 builders and owners do not need to update to the 2nd edition drawings, unless wanting the gross weight increase.
