<DIV><FONT face=Arial size=2></FONT><BR><FONT face=sans-serif size=2>I agree
with Troy..get something established and fly it. I have a Bridi
Escape...Thought I would "make it fly better" so I removed alot of the
prescribed dihedral...now left rudder gives right roll, and right rudder
gives left roll....try getting used to that! The guys who designed and
kitted these planes pretty much had it figured out. The rule may be......Does
the damn thing work??? Yes?? </FONT></DIV>

encounter a model with adverse roll you will likely be able to fix
it.</FONT></DIV>

big area wise for a 90<BR>sized bird. You need something in the 800-900sq-in
range....The Prophecy is<BR>up around 980 -1000...This is the same wing that
is on the Focus, Hydeout,<BR>PHD, Temptation, and so on....Its a 2M 10lb to
10.5lb bird platform not a<BR>8-9lb platform....<BR><BR>The Bridi
designs have good wings on them use it. You are not going to gain<BR>anything.
In this situation a successful conversion would mean that you<BR>didn't screw
up an already good flying model.<BR><BR>Just my advice. Worth what you paid
