Plug your servos and ESC into your receiver, attach your battery and test your radio system. Check for

correct motor running direction now, before your prop is installed. Never run your motor inside a

building with the prop installed. Check for correct servo direction, reverse as necessary. Center all

control surfaces and tighten pushrod adjusters securely.

Scott's Tip:

Your aircraft has an extremely wide CG range. While some pilots prefer a

dramatically aft CG for 3D flight, or a conservative forward CG for precision aerobatics, I

generally split the difference and fly with the CG set just slightly forward of neutral. What

this means is that the aircraft will require only the lightest breath of down elevator during

inverted flight. I've found that this setting has excellent tracking for precision and no

coupling during KE flight, while still offering excellent 3D performance. My personal setup

is as follows:

Reasonable CG range

Preferred CG location

The easiest way to measure CG is done using your fingertips holding the model

upside down. It is also the least precise. For more precision, there are several commercially

available balancing units. Realistically, however, I generally get the model close on the CG

stand, followed by fine-tuning based on the feel of the model in the air. Fortunately, this

aircraft has a very long battery tray, allowing you to set it up to match your preferred flying

style.
