I fly my Slow Stick with a Himax 2025-4200, and a Cobri gearbox.

I have two suggestions for you:
  • Looking at the photo you posted, your airplane is very much tail heavy. The CG point of the wing is forward of where you have the pencils. (Actually the square-head (new) pencil erasers will make the airplane easier to balance -- you're better off using USED erasers for testing your balance). Try this:
    1. The manual shows were the CG point of the wing is -- measure, and mark the CG point on the wing, with a pencil or pen.
    2. Remove the wing from the airplane, and find the CG point of the entire airplane (without the wing, but including the battery). Mark this spot on your airplane with a pencil or pen.
    3. Reattach the wing so that the two CG marks (fuselage and wing) line up.
  • The Himax 2025-4200 is a very powerful motor (I use mine to lift a Pentax Optio S40 4-megapixel camera into the air for aerial photography)! The Slow Stick doesn't need much power to fly. New pilots tend to apply too much throttle when flying. Try this:
    1. Put the Slow Stick on the ground, point her into the wind, and very gradually apply throttle, until the Slow Stick just leaves the ground. When she leaves the ground, reduce throttle until she lands -- just fly in a straight line for this step.
    2. Keep doing this, until you feel comfortable looking down at your throttle stick for a few moments.
    3. Now that you know where your minimum throttle setting is, try to fly the airplane at about that same setting (maybe a little higher, but not much).
Let me know if you have any questions. I'm happy to help!
