I am getting ready to assemble my USL 120. I noticed that the engine thrust is NOT built into the firewall. I also noticed that nowhere in the manual does it mention engine thrust or what it should be. Does anyone know what the engine thrust angles should be on this airplane? I am going with a TT120 2 stroke if that makes a difference. PLEASE HELP!!

Thanks,
Allen

Mine has a Webra 120 and I have setup two others for other folks both with ST G2300 (140) and no right or down thrust is needed just mount the firewall as is. This is a very nice capable airplane and not difficult to fly at all.

I had an Ultra Stik (older style) - had no right thrust built in - flew fine with a saito 180.
