I seem to everything under control except I need serious trip to keep it from turning right. Here are his instructions:
Step 2: Trim out the forward or backwards movement of the heli.
Pop off the servo linkage responsible for forward and backwards flight. You can simply move the remote stick forward and backwards to so you can determine which servo linkage is responsible for the forwards and backwards movement of the heli.
If the helicopter moves forwards. Then you have to lengthen the linkage to give it some backwards trim. Simply turn it counter clockwise to lengthen the linkage. I find that on the 9958, you can do a complete full turn or half turn. How many turns clockwise depends on how much trim you need. Just roughly guess. I'll start with 5 complete turn if there's a lot of forward momentum.
Conversely, if you the helicopter moves backwards. You shorten the linkages by simply turn the linkage clockwise.
Step 3. Trim out the left or right movement of the heli.
The concept is the same as the above.
If your heli is moving too much to the left. Twist counter clockwise to lengthen the servo linkage.
Conversely, if your heli is moving too much to the right. Twist clockwise to shorten the servo linkage.
I'm not sure exactly what I'm twisting clockwise.
Oh, and 2 batteries isn't nearly enough
