Swager

With a 46FX in the Four Star you'll see what I mean if you build it light as per plan.

I didn't want to say it earlier lest it be seen as "disparaging" <grin> but as one who is used to and likes lots of power for pattern verticals, a powerplant in this class is a both mismatch and excessive in the Four Star IMHO. Its not a 3D design. I've tried a few powerplants including a 46FX equivalent in the Four Star and found the largest 2 stroke offering preferred in it the equivalent of a 40FX. Even this is power in abundance for the Four Star 40.

Whilst a 46FX inarguably offers greater (unnecessarily) sustained vertical, it is accompanied by the disadvantage of constantly retrimming to accomodate small throttle changes which represent larger thrust changes effecting speed and the AoA relationship given the aerofoil and wing loading of the Star. In simple-speak what I'm saying is that it's simply unnecessary and spoils the intended characteristics of the design such that unlesss you want to be constantly climbing unintentionally, you'll be on/off the throttle all the time and retrimming rather than setting her to "Give her all she's got Scottie" power, trimming and concentrating upon finessing manoeuvre for the most part.
