Hi all,
The kit supplied engine exhaust pipes are flattened along their entire length.
However, most photographs of the aircraft show the exhaust pipes at the engine end being flattened, but then changing to tubular shape at their outer ends.



The replacement exhaust pipes were made as follows:
File or sand away the locating stub on the engine side of the exhaust pipe flanges.
Carefully cut away the exhaust pipes close to the flange.
Using thin CA adhesive, secure each flange centrally onto the exhaust outlets of the engine cylinders.
Cut a 10 mm length of 2.0 mm diameter Brass tube, such as ?Albion Alloy?s? (MBT20) or similar.
Using flat pliers, carefully flatten one end of the tube and reduce the flattening outboard to approximately half way along.
The bore of the flattened end should be approximately 0.5 mm wide.
Cut a length of 0.5 mm diameter Brass rod, such as that from ?Albion Alloy?s? or similar.
Insert the rod centrally into the flattened end of the tube, leaving approximately 4 mm protruding.
Secure the rod in the tube using either thicker, slow setting CA adhesive or soft solder the rod in the tube.
Drill a hole of 0.5 mm diameter centrally into an exhaust flange.
Test fit the exhaust pipe into the engine, making sure it?s 90 degrees to the engine when viewed from above and from the front.
Repeat the procedure to create the remaining five exhaust pipes.
