Power Train-Rebuilt S1

Had to reconfigure the power train. Sent the venturi to the local machine shop for modification to take an O.S. control line fuel nozzle from the LA series engines. Installed a remote needle valve (O.S. R/C type) under the fuselage. Found it necessary to use muffler pressure. Am posting some pictures of the new installation because a picture is worth a thousand words.
This thing is really fast now!
