Re: Nose pitch's up
You may have too much down thrust on the engine

Re: Nose pitch's up
My friend said the same thing but when I put the plane straight vertical and go to full throttle It doesn't pitch to the wheels but slightly toward the canopy.
Also I worked on the torque roll again today and we made some progress with the plane. All I can say is that manuver is a royal pain in the butt. He also said that it's a difficult plane to torque roll but everyone says the 40% Carden Edge is one of the easiest.I can't quite figure that one out just yet.

Re: Nose pitch's up
What size PAU Ege do you have? Do you have any mixes programed into your Tx? Is your cg at the recommended spec?

Re: Nose pitch's up
The CG seems good.When I roll inverted its almost hands off. If I add any additional up thrust it will pull to the canopy at full throttle going vertical. I'm really baffled on this.

Re: Nose pitch's up
What does it do when you do a verticle downline at idle (does it pull to the canopy or lg)? If it pulls to the canopy you can add a mix so that when at idle it will apply enough down elevator to keep it straight. That should get rid of what you are seeing now.

Re: Nose pitch's up
I had more up thrust in the plane before but I took some out because it was pulling to the canopy slighly in the vertical.

Re: Nose pitch's up
Well I covered all that I could think of, sorry. Hopefully someone with more experience can help you out. I am interested to find out as well, you never know one may come across this in the future. To me, if the downline is straight then when flying a horizontal straight line and you go to idle it should continue to go straight.

Re: Nose pitch's up
I went out to the field today with the PAU Edge and tried the straight down line and the plane holds is track.What I ended up doing was add a slight throttle to elevator mix and that solved the nose pitching up.

Re: Nose pitch's up
Is the mix on a switch? If it is always on, what does the plane do when you do the verticle downline now?
