Aware of that. Not that I am always in abeyance of it, but it's called staying on topic. In the absence of an answer to date, the thread having been revived, my intent was to assist others who might pose the question.

Sure. That's what life is about. You're a four stroke afficionado. You like heavy models with high wing loadings because they "grove" (sic) I'm not. I don't.

It does however explain why you prefer to fit to your models the the biggest or slightly oversize capacity engine for class and a four stroke with gobs of torque.

The original inquirer asked about the .46FX specifically. I answered him specifically. 46FX is about the performance equivalent of a typical sports FS-70, but both a lighter (a big plus in Pattern) and cheaper. Adequate for the job with gobs of power for 2006 Sportsman manoeuvres. Torque? Academic for the purpose of this exercise. Understand you prefer it.

In any case, if more power including torque and a quieter run at lower RPM was wanted, for about the same total outlay as the OOTB equivalent brand FS he could add a pipe. A Just Engines purple Hatori copy would be just the thing, a lot more fun to play with and much more useful in terms of the learning curve as he'll be adding one to his next engine model combo if he were to progress to Advanced.

Undeniably there are a pletoria of alternative powerplants he could use. It comes down to what he has availabile and wants to use ie: .46FX as stated), can afford to use (we're all not rich bu99ers), and preference.

The most crucial criteria for his stated intended "first pattern plane" purpose and intended "46FX" engine is will have sufficient vertical performance for purpose given the Groovy F3A design and weight. The answer to that is yes. We've been down this road before. Lighter is better.

Lou55 BG is correct. There are two versions of this model. The 3A variant is the pattern designation. The 3D is the 3D variant.
