G'day

I am currently building a Bruce Tharpe Engineering Flyin' King. It can be built either with or without flaps but Bruce suggests they be included. The Flyin' King is described as a multipurpose load carrier. It is 81.5 inches wingspan and will have an OS 95V four stroke in it. http://www.btemodels.com/flyin_king.html

Bruce's excellent instructions suggest that flap to elevator mixing be used to add 4 degrees of down elevator at full 40 degrees of flap. And of course, more power is needed with flaps deployed to overcome the drag that they induce.

As an aside, the kit is really excellent. I am really enjoying building it, or I was until I managed to build two right ailerons. AAAAAAAGH! It was my fault, I put the second set of ribs inside the ailerons upside down so today I am off to buy a few sheets of balsa to undo the problem.

Cheers

PS Bruce designed the Four Star series when he worked at Sig. His Venture 60 is an improved version. Must build one some time.
