<br><font size=2 face="sans-serif">The plane would have been alot more fun had I NOT messed with it. Now I do not have the time to make another wing. I choose to let someone else mess with an old design. I did learn that when I got my Prophecy kit from you NOT to mess with it. Built it per the plans!!<br>

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>
<br><font size=3 face="Times New Roman"> </font>
<br><font size=2 face="sans-serif">** Great! You proved it. The next time you encounter a model with adverse roll you will likely be able to fix it.</font>
<br><font size=3 face="Times New Roman"> </font>
<br><font size=2 face="sans-serif">Do not Freak with it. Ever wonder how much better a KAOS would fly with a YS 140? </font>
<br><font size=2 face="sans-serif">**Yes I have.....</font>

Why is the big rush to change the wing on these designs.....?<br>
<br>
Why not take the proven airframe build it and fly the living heck out of it.<br>
My personal opinion is the Prophecy wing will be too 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 for it<br>
<br>
