If I shorten the distance from the leading edge of the horizontal stabilizer to the trailing edge of the wing.....will that make my "up-down" control more sensitive( jerky and less control?) chas Ps I was running low on boom material...ha!

Several effects by reducing length of boom:
- less pitch inertia (will liven response to your inputs).
- less leverage for you stab (less pitch stability).
- your moving surfaces will have less authority for the same deflection (less leverage).
- your rear surfaces will be more affected by turbulences created by the main wing.
- less weight, so change of your CG.

The very short fuse of the aerobatic gliders I fly are generally pitch sensitive and very lively in pitch, but they also have very big rear moving controls surfaces.

Cheers.
