Hi, David Two things happen, which has - more or less - the same effect: As the power of the tail is tail arm length times the tail area, you'll get a powerful tail, but due to the long tail arm's weight you will get some inertia effects, too. So when the wing is lifted by a thermal the tail will make the wing pitch up more than with a shorter tail with the same tail volume, as one says (tail arm length, times tail span, times tail chord is tail volume). If the tail area is normal the same will happen, but this time due to the longer tail arm, with its greater inertia, and the higher tail volume! So stabler flight & more powerful elevators, that's the main effect - unless there are tail boom bending/flutter problems :-)!

I seem to have been in the same class, as my sketches seldom look like the finished product (I usually do a new sketch afterwards, using the finished product as the model - makes the sketch and model look much more the same). Lately I worked mostly with aluminium and stainless bolts - yeah, not model aircraft, but rigs and other stuff for my small boat ... Tord RCSE-List facilities provided by Model Airplane News.
