There is lots of Viper jet info here on RCU. One of the threads is called "return of the viper jet" and it has some new landing advice from Tam, the settings are noted on this thread too:

Miguel,
Keep it coming buddy.
My lastest Viper Jet I set up crow ailerons with full flap. She land really nice and slow. I don't need speed brake at all.
Imagine land the Viper Jet with power and Dave can grease her less than 300 feet at our county field. Before we had to use up all the runway.
You can see how our field look like from Super Hornet DVD.

I will get the surface throw for you this weeken. I'm very busy preparing for Superman Jet s week right now. Hope this saturday will take care it for you.
