I, for one, recommend larger horns and bellcranks for the smaller models.

Our flying handle has to use a reasonable separation distance between the lines. Too large, used with a 2" 'span' bellcrank, will CAUSE the dreaded 1/2A model twitchiness. Our comfortable 'tilt' angles to input controls, with a handle large enough to fit our hand, will send a 1/2A bellcrank too far, too fast.

We COULD learn to use much smaller input motions, if the model lasts long enough. We COULD learn to adjust lines for a comfortable 'neutral,' which is also more finicky with a small line separation. A bit larger - I'm **not** saying put a 4" span bellcrank on a Little Wizard!

Longer control horns help slow response. A 2.5" 'span' bellcrank is much easier for our existing motions to fly than a 2" - the angles are reached a bit slower, and the line can be separated a bit more at the handle. It all becomes more familiar, more like the response feel of larger models.

The points about HOW you make your horns, and possibly bellcrank as well, are excellent.

Appearance of "being 1/2A" should be secondary after choosing things that improve the enjoyment of flying a little one.

Interested to follow your progress!
