Cool

Well RC4WD makes a servo throw adjuster that plugs in-line between the servo and Rx. This is the eisiest solution.

The other is to try and move the link mount on the servo horn as close to the screw head. There is less movement(throw) here then out by the end of the horn. I used a plastic horn with several small holes and kept moving it in until the throw was close enough to engage the gears without slipping the shift or straining the servo. Look at the pics and you'll see i'm bout in the middle of the horn.

Check your driveline angles, they may be too extreme. If you have the tranny sitting in the bottom holes to give max clearance then try the top holes and see what happens. If this is it, then you may want to get the axle wedges to rotate the axles and relieve your angle issue and you can go back to the lower holes.

Then also check the mesh of your motor, the pinion to the spur. It might be too tight.

If problem still exist then you may need to take tranny apart and make sure everything is free moving and not bound up and plenty lubricated.
