During the construction of the Su-35/Su-37 Conversion Kit we discovered an error in the shape of the cockpit hatch
and cockpit hatch rails.
This error occured because of an earlier change to the size of bulkhead B2T/B2B. When the size of the bulkhead was reduced, the cockpit hatch railes should have been updated to match the new cross-section.
This tech note contains full-size drawings that can be printed and used as templates to cut a new cockpit hatch and
cockpit hatch rails.
The cockpit hatch and cockpit hatch rails that came with the Sukhoi Su-27 kit should be discarded as they will not fit
NOTE: If you already purchased a Su-27 kit and you haven't yet built it, contact Savage Light Industries and we'll mail a corrected laser cut sheet to you at no charge.
