Stiletto tail size

(1/6) > >>

Dietmar Morbitzer:
Hello stunt pilots,
I've started to build a Stiletto 660. The tail size is under 20%
of the wing. I've learned that the tail shout be in the range of 25+%
of the wing. Does somebody have experience with a bigger tail
on a Stiletto and in which direction should it grow?

      At least around here, that will make it not legal for Super 70s/Nostalgia 30, if you care about that.

     I will preface this with  - I probably wouldn't do this for a variety of reasons, but if I was, and the only option was to add to the existing tail, I would add it entirely in chord and only to the stabilizer. That will reduce the aspect ratio and reduce the stabilizer/elevator split. If I was going to replace it entirely, I would design a tail with about a 4.25:1 aspect ratio, a 65/35 split, and about 25-26%

Perhaps youd better let Les McDonald Know. He might want to change it before He starts Flying It . :) ;)

Target:
Les himself told me that in later years the following mods were popular on the Stiletto 660:

Make the cord 1/4" wider on the stab.
Make the cord 1/4" wider on the elevator
Both of the above is for the full span.

Make the outboard flap 1/32" wider.

Hope that helps you.

That's what he told me....
Take it or leave it.

Puts the precision in precision stunt.
