Hello,

Many years ago, I started to build an ElectroFreshman; a kit from the now defunct Premier Balsa Products. It was to have been my first aircraft of this type. Then a house move got in the way, and the project was shelved.

I recently rediscovered the forgotten, half-built 'plane in the loft, and a brief search finally turned up the rest of the kit. I think the time has come to finish it, since I've had it since 1991...

Trouble is, I only have half the model plan. I have the (very scanty) instructions, and plan and elevation for the fuselage, but I appear to have lost the top half of the plans, probably still pinned to a building board and left behind during the house move.

I have already built the wing centre sections. I have a full set of ribs, and I know the total wingspan, so I think I can deduce enough to get the outer wing panels built.

The fuse and fin/rudder are no problem - I have the parts and plans.

What I don't know is anything much about the horizontal stabiliser. It's made from sheet, not built up. Nice and simple, but I have no idea what its span ought to be.

Model's vital statistics:
72 inch wingspan
53 inch length
approx 550 sq/inch
approx 22 ounce<div id="TixyyLink" style="border: medium none ; overflow: hidden; color: rgb(0, 0, 0); background-color: transparent; text-align: left; text-decoration: none;"></div>...and that's about all I know. Anybody care to hazard a guess at the dimensions or surface area of the empennage? Is there a formula I should use to determine this?

Any thoughts appreciated!
