I lost my instruction book for this phoenix extra 300s ARF.

Does anyone know what engine thrust this plane calls for if I use an OS 55AX engine on it?

EDITED.....I found the answer....it's already built into the firewall!

One guy once told me he uses No thrust on any of his planes. Could this also be true?

I'd like to know.

All ARF planes have thrust already setup in the manufacture of the firewall. I have had to add some down and right thrust on electric planes when I put bigger than recommended motors on them.
