    Guys, I have a pattern plane that pulls to the canopy on the downline(throttle off)..I need to mix the throttle /elevator so it has a touch of down ...How do I do that without having the trim knocked all out of whack?? thx...

    Try a throttle to elevator mix at about 2%, so that when the throttle is at idle, you have about 2% down elevator

    Also that mix witch is used a lot in IMACC should be on a switch. If not it makes landings interesting. Dennis
     

  6. That depends on your CG...

    If you are flying a nose heavy airplane, then yes, it will cause it to pitch down more on landing (just hold a little elevator on final). If you're flying a tailheavy airplane, they tend to pitch up on landing anyway, and wouldn't hurt to have some down in there.

    For both my 3D and precision flying, I leave the mix on at all times. Just one less thing I have to worry about while flying.

    Sounds to me like you are nose heavy and so carrying a lot of up trim. The the inverted 45 degree upline test, I bet you need to hold down elevator to stop it diving. If so then you need to move the CG back and re-trim the elevator.
