Default Motor tightening tip

For those of you who haven't yet built the model... there is a concern about how to tighten the motor, as the motor screws are partially blocked by the servos once they have been installed. Someone suggested using a ball-tip hex wrench, which will allow you access to the screws at an angle. I have one on order, but it didn't get here in time.

For those who haven't yet installed the servos: You can test fit the rotor head, install the main gear, and adjust and tighten the motor before installing the servos. Then remove the head and install the servos. At that point, you're all set up when you install the head/shaft again. Eventually, you'll want the ball-tip wrench, as you won't want to be removing servos in the future to adjust the motor gear mesh. But hopefully this tip will get you going if you don't have that wrench yet. Neall

IIRC you can also take a few screws out in front that hold the upper/lower frames together, then swing the upper frame out of the way.

I went to Home Depot and picked up a 1.5mm ball end allen wrench and called it done.

cheers,
Leslie
