<HTML><FONT FACE=arial,helvetica><HTML><FONT SIZE=2 PTSIZE=10 FAMILY="SANSSERIF" FACE="Arial" LANG="0">I flew the Alliance for two seasons in Masters and found it to be an exceptional perfrormer
. I had the wing incidence set at 1/4 degree positive, with stab at zero and engine as per the built in nose off sets. <BR>

Webra 145 powered mine with a 16x14initially, and I set the pipe long, (conservative)
. Eventually went to more typical set-up on pipe setting and the plane improved in power authority. <BR>

It sounds like you may be underpropping the L some. The L has enough beans to turn a 16x13N just fine. </FONT><FONT COLOR="#000000" BACK="#ffffff" style="BACKGROUND-COLOR: #ffffff" SIZE=2 PTSIZE=10 FAMILY="SANSSERIF" FACE="Arial" LANG="0"><BR>

I set the cg at the recommended location and found that to be too nose heavy for me. I eventually pushed the cg back approximately 15 mm from stock, and everything improved. <BR>
<BR>
About the only negative on this design was the amount of "UP" mix required to fly a true knife edge-- about +8% both sides, and could have probably used +10%. The aft cg location I was using was a good compromise between overall flyability and the amount of UP mix to fly knife edge.<BR>
<BR>
In terms of ability to lock in any attitude, it was one of the best I have flown. It's ability to hit angles with precision, and fly true up and down lines was outstanding. I am surprised that you are finding the plane tough to fly with precision. Have you gone back and re-checked all of your settings? <BR>
<BR>
Hope that helps you. Good luck<BR>

I am trying to decide which of my plane will be my primary this year. I have an Alliance/140L/15x12W/25% and a Hydeout/160FX/17x13/15%. Both are just under 10 lbs. <BR>
After practicing a few weeks with the Hydeout to start the season, I took the Alliance out also to see which one feels better for me. I have now 30 flights with each one this year and I am still struggling with the Alliance. I can't get nice straight lines (horizontal or vertical), the rolls on 45 are not straight and the snaps aren't nice. When I fly the Hydeout, everything is a lot better. <BR>
The CG of the Alliance is already moved aft of the instructions but I still need a lot of elevator for inverted flight. I tried more aft but it didn't fix it and I am now thinking about moving even more aft. The plane is very stable at low speed and the rudder as a lot of authority. It easily loop in knife edge. The elevator and ailerons also work very well. I tried a 15.5x13N and a 16x10 without improvement except for better vertical with the 16x10.<BR>
The Hydeout is more powerful and easily makes big maneuvers. The roll rate going up or down looks very similar so I am assuming that the speeds are similar too. The rolls on 45 are better.<BR>
I fly the P05 in approximately the same time (around 8 min) with both airplanes but with some maneuvers bigger with the Hydeout.<BR>
Could it be that I fly the Alliance too slow ?<BR>
Should I move the CG more aft and how far back could I move without trouble ?<BR>
Any other ideas to help me taking the better decision ?<BR>
<BR>
Thanks<BR>
