[NSRCA-discussion] trimming

[johnfuqua.jf at gmail.com]

Thanks for the feedback.    May be a while before I can try what has been suggested.    I start with the easy and move to the more involved.   

 

As a point of reference it’s a Zonda with a pletty for power.   21.5x13 prop.    CG is right on manufacturers suggested point.    Determining thrust line, stab incidence is the difficult part.

As we also know, there’s no such thing a too much power. And way, way, too much is about right!

John,

You got very good information.  For sure we would like to know if you fix it and what you did.  Something that I would like to add.  Just use the correct amount of power required to do the up line.  As we know, too much power corrupts.  

Good luck,

.

Which airplane?  Not all designs behave the same way.  I had one modern design plane that no matter what I tried always pulled to the canopy in the vertical.  

But as already mentioned start with incidences.  Positive in the wing will help. If the incidence is correct to start then move the CG back.  Finally add downthrust.  

 

My Hebert designed planes have always been very sensitive to CG in this respect.  My Mythos much less so.

Real quite on the list.   Need some advice.    What is the trimming fix for a plane that is pulling to the canopy in a vertical upline ??
