Thanks for the replies.

The instructions for my (cheaper) pattern plane do not specify engine mounting offset.

I have converted the plane to a nosewheel config due to the dusty an very rough field I fly off.

I felt the plane had too much offset after my mods (i had repostioned the engine).

I have reduced the offset and applied a little down thrust since posting this post.

Just interested if the more expensive pattern planes instructions actually specified how much engine offset and down thrust (if any) should be set.

It has been windy conditions during the flight test today, so difficult to tell if the mods are an improvement over the previous setup. Even with vertical climbs (was blown off the vertical).

Do the more expensive pattern planes specify offset.

My plane is a Phoenix Atlantis (poor mans pattern plane)

Cheers.
