Different side or down thrust angles
Gents
Thanks for the advice. The plane I am flying is a 1970s design called the Tornado. It has no side or downthrust but I am using a modern 60 in it. Everything else does check out.
Basically what you are telling me is that if I build a modern pattern design ( which I am currently doing) it should require no engine offset other than that already built in.
For your info I am currently building a MK Skystar which was built for a YS90 but I am putting a Webra 80 long stroke into it.
