I must confess to being a tad confused by the pictures of the Circus Circus Tipo and the Hippo Tipo. The Circus Circus Tipo has anhedral in the horizontal Stab and the Hippo Tipo seems not to have it where my Hippo Tipo has the anhedral. Was it an option left to the builder whether to put in the anhidral or not? Sorry for the crappy spelling.
JAY.

Upon taking another look at the pictures it may be the way the picture was taken.
