Am working on parts and plan for a slow flying old-timer. My book says when converting to aim for the elevator to be about 20 percent of total Hoz-stab area. That seems both large and small to me. Very same A/C was flown fine with much-much smaller elevator. but then too my booklet says to aim for 30 percent.

The total area of the Hoz-stab in now about 130 SI.

What size you think it ought to be?
