Big Pete, I found a picture of your parts/setup in;
http://www.castlehillhobbies.com.au/dubro.htm
Look for pictures of Dub152 and Dub664. In Dub152 you`ll see the exact setup that zetor showed you, but you will not use the nylon steering arm ( see Dub155 ) that is shown on that picture, you`ll use the E/Z-mount-steering arm Dub664, which mounts lower and probably with a steering push-rod that comes exposed from the belly of the airplane. PLEASE do not hesitate to ask us any questions, me, and I know many others will be happy if you get that "bird" assembled soon.
