Quest questions...

[Earl Vincent]

Plans say 165mm approx 6.5 inch from leading edge if he is balanced there then what Eric said about the
thrust line is true if your below the planes intended thrust line it will act like up thrust and above it will act like
down thrust, the kit is a little strange, it mounts the inverted engine on the top of the engine bearers. making the
actual thrust line approx 1/4 inch above the top (looking from the top of the plane) of the maple beam installed in the firewall per the plans. Most engines center of thrust is the bottom or the machined surface of the side lugs, I missed it at first and had ordered the wrong rise header from Karl. If balanced corectly and thrust line
is ok  the elevators should be straight when trimmed for level flight.

  Emory, What is he using as a motor mount on the electric, make sure he does not have up or down thrush in the motor, it should be at 0 down with 2 degrees right. No wing shimming was done but this plane even when
  very tail heavy takes some down inverted, when you are to tail heavy it will be a bear to land. I learned the hard way. I may have stated the pitch wrong, under med rudder inputs i.e. normal knife edge no mix, hard rudder
  inputs knife edge loops etc. it will come to the canopy slightly.

    Hello,

    I wanted some input from those of you that have been flying a Quest from Creek Hobbies. A guy at my field is flying one and is trying to get it trimmed correctly. He has it set-up using an electric motor, similar to what Jason flew at the worlds. The power is great and the speed is so consistent. He will be flying intermediate and I think that is going to be a great plane. Anyway, here are my questions...
    1) Where are most of you running  your CG? He has his about 1/2-3/4" behind what is recommended.
    2) Did you have to adjust or shim the wing to get the proper incidence?

    Most of what I have seen posted on this list about that plane is that it doesn't require any mixing. His pitches to the canopy in knife edge and requires a lot of down pressure on the stick when inverted. Any help is appreciated.

    Thanks, Emory Schroeter.
