I have seen engine mounts that have special rubber pieces to reduce vibration wear on airframe. With one of these, do you think that a 120 fs(if it will even fit) would be ok, or still too much. At a possible 9lbs, I just think a 91fs wouldn't be enough, and I don't want a 2-stroke.

wolf... 3.3kg = 7.27lbs!!! What did you do to get it this light. The webpage says 8-9lbs, I have never seen anyone overquote a models weight.

What scale pilot should I use? 1/5?

Thanks

P.S. Any suggestions on specific hardware replacement would be super.(4-40?)
