I mean no offence, but isn't it so much easier to just install a belly board and get the same or better results. I know that I am not flying yet and maybe I am not one to say this, but you can "build" this thing forever if you keep re-inventing it.
See N64KR at http://KRBuilder.org - Then click on the pics See you in Mt. Vernon - 2006 - KR Gathering There is a time for building and a time for FLYING and the time for building is OVER. Daniel R. Heath - Lexington, SC -------Original Message------- Hi Netters. Take a look at Chris Heintz's Zenair series. He uses a reverse airfoil on his horizontal stabilizers. This provides the necessary down moment on the tail to maintain stability. It is like a automatic trim control.
